Menu: `Run` -&gt; `Edit configurations` -&gt; `&quot;+&quot; (add new config)` -&gt; `Python`.

Script name: `program.py`

If you need to debug a script from installed packages, such as `tox`, you can specify the full path too. For example:
Script name: `/home/your_user/.envs/env_name/bin/tox`

Above `/home/your_user/.envs/env_name` is a path to virtual environment containing `tox` package.

Script params: `-t input1 -t1 input2`

Just the image wise representation of answer

step 1: Click on the ```Run``` menu click ```Edit configuration```

I am writing a Python program in `TKinter` on Ubuntu to import and print
the name of files from particular folder in `Text` widget.
It is just adding filenames to the previous filnames in the `Text`
widget, but I want to clear it first, then add a fresh list of filenames.
But I am struggling to clear the `Text` widget&#39;s previous list of
filenames.

Can someone please explain how to clear a `Text` widget?

Screenshoot and coding is giving below:

I have been using PyCharm for a bit so I am not an expert. 

How I normally ran my programs was with the terminal like so:

`program.py -t input1 -t1 input2`

I was wondering how can I debug this? 

For other programs I wrote, I did not have any arguments so debugging was simply setting break points and pressing debug.

In unittest, I can setUp variables in a class and then the methods of this class can chose whichever variable it wants to use...

    class test_class(unittest.TestCase):
        def setUp(self):        
            self.varA = 1
            self.varB = 2
            self.varC = 3
            self.modified_varA = 2

        def test_1(self):
            do_something_with_self.varA, self.varB

        def test_2(self):
            do_something_with_self_modified_varA, self.varC

So in unittest, it was easy to put bunch of tests together that could go under one class and then use many different variables (varA and varB) for different methods. In pytest, I created a fixture in conftest.py instead of a class in unittest, like this...

    @pytest.fixture(scope=&quot;module&quot;)
    def input1():
        varA = 1
        varB = 2
        return varA, varB

    @pytest.fixture(scope=&quot;module&quot;)
    def input2():
        varA = 2
        varC = 3
        return varA, varC

I feed this input1 and input2 to my functions in a different file (let&#39;s say test_this.py) for two different functions. Here are the questions based on information above...

1. Since I can&#39;t just declare local variables in conftest.py as I can&#39;t simply import this file. Is there a better way of declaring different variables here that can be used in different functions in test_this.py ? I have five different configurations in my actual testing for these variables, defining that many different fixtures in conftest.py and use them as function argument in five different functions in test_this.py sounds painful, I would rather go back to unittest class structure, define my variables and pick and choose what I want

2. Should I just declare global variables in test_this.py and use them in the functions the way I want ? Seems a bit not pythonic. This variables are only used by the functions in this file.

3. Let&#39;s say I have test_that.py and test_them.py as well. If I have some shared variables between these different files, how would I declare them ? just create a file calle variables.py in the directory where all these test files are and do an import whenever I need ? This way I can keep all data in a separate.

4. Is it my impression that pytest discourages using a class to organize your functions ? Every example I read online, it all seem to employ bunch of functions with fixtures only. What is a configuration of defining class and methods and organize tests in pytest ?

5. I have a test scenario where I have to use result of one function into another. With pytest, I have an assert that is at the end of a function not a return so I won&#39;t be able to use this function  as a fixture. How do I accomplish this ? I know this is not a good practice that my one test relies on another but is there a work around ?

Thanks in advance for your answers.



unittest Vs pytest

If I am using argparse and an `if __name__ == &#39;__main__&#39;` test in a script that I would also like to use as a module, should I import argparse under that test and then initialize it? None of the style guides I have found mention using argparse in scripts and many examples of argparse scripting do not use the &#39;if name&#39; test or use it differently. Here is what I have been going with so far:

    #! /usr/bin/env python

    def main(name):
        print(&#39;Hello, %s!&#39; % name)

    if __name__ == &#39;__main__&#39;:
        import argparse
        parser = argparse.ArgumentParser(description = &#39;Say hello&#39;)
        parser.add_argument(&#39;name&#39;, help=&#39;your name, enter it&#39;)
        args = parser.parse_args()

        main(args.name)

Should I import argparse with my other modules at the top and configure it in the body of the script instead?

I want to drop rows from a pandas dataframe when the value of the date column is in a list of dates. The following code doesn&#39;t work:

    a=[&#39;2015-01-01&#39; , &#39;2015-02-01&#39;]
    
    df=df[df.datecolumn not in a]


I get the following error:

&gt; ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().


dropping rows from dataframe based on a &quot;not in&quot; condition

Assume we have a data frame in Python Pandas that looks like this:

    df = pd.DataFrame({&#39;vals&#39;: [1, 2, 3, 4], &#39;ids&#39;: [u&#39;aball&#39;, u&#39;bball&#39;, u&#39;cnut&#39;, u&#39;fball&#39;]})

Or, in table form:

&lt;!-- language: lang-none --&gt;

    ids    vals
    aball	1
    bball	2
    cnut	3
    fball	4

How do I filter rows which contain the key word &quot;ball?&quot; For example, the output should be:

&lt;!-- language: lang-none --&gt;

    ids    vals

    bball	2
    fball	4

Im trying to install numpy with PyCharm but i keep getting this error: 

&gt; error: Microsoft Visual C++ 10.0 is required (Unable to find

Can someone please explain to me exactly what i have to do to fix this error(and as simple and detailed as possible)? im using python 3.4.2 (i know this has been answered before but i did not understand it).

I am new to PyCharm. I have a directory that I use for my PYTHONPATH: `c:\test\my\scripts\`. In this directory I have some modules I import. It works fine in my Python shell. 

How do I add this directory path to PyCharm so I can import what is in that directory?

PyCharm and PYTHONPATH

I&#39;ve got Pycharm 4 running on my Linux (Ubuntu 14.04) machine.  In addition to the system python, I&#39;ve also got Anaconda installed.  Getting the two to play nicely together seems to be a bit of a problem... PyCharm provides some interesting integration for `virtualenv`s and `pip`, but the Anaconda Python distribution seems to prefer using its own `conda` tool for both activities.

Is there a relatively simple/painless way to be able to use `conda` in conjunction with PyCharm?  Not just as an alternative interpreter i.e. point PyCharm at the Anaconda Python binary for a project interpreter, but to be able to create, source/activate and deactivate virtual envs, add/remove packages in those virtual envs, etc. 

Or am I going to have to choose between using Anaconda (and having a more recent and up-to-date python than may come with the system), and being able to use PyCharm&#39;s features to their fullest extent?

Using (Ana)conda within PyCharm

I have written a module (a file `my_mod.py` file residing in the folder `my_module`).
Currently, I am working in the file `cool_script.py` that resides in the folder `cur_proj`. I have opened the folder in PyCharm using File -- open (and I assume, hence, it is a PyCharm project).

In ProjectView (CMD-7), I can see my project `cur_proj` (in red) and under &quot;External Libraries&quot; I do see `my_module`. In cool_script.py, I can write 

    from my_module import my_mod as mm
 
and PyCharm even makes suggestion for my_mod. So far so good.

**However, when I try to run cool_script.py, PyCharm tells me 
*&quot;No module named my_module&quot;***

This seems strange to me, because

A) in the terminal (OS 10.10.2), in python, I can import the module no problem -- there is a corresponding entry in the PYTHONPATH in .bashrc

B) in PyCharm -- Settings -- Project cur_proj -- Project Interpreter -- CogWheel next to python interpreter -- more -- show paths for selected interpreter icon, the paths from PYTHONPATH do appear (as I think they should)

Hence, why do I get the error when I try to run cool_script.py?  -- **What am I missing?**

Notes:

- I am [not declaring a different / special python version](https://stackoverflow.com/questions/25150355/requests-module-works-in-console-but-not-script-all-other-modules-work-normall) at the top of cool_script.py
- I made sure that [the path to `my_module` is correct](https://stackoverflow.com/questions/19885821/how-do-i-import-modules-in-pycharm)
- I [put `__init__.py` files (empty files)](https://stackoverflow.com/questions/12284667/django-error-no-module-named) both in `my_module` and in `cur_proj`
- I am not using `virtualenv`


# Addendum 2015-Feb-25
When I go in PyCharm to Run -- Edit Configurations, for my current project, there are two options that are selected with a check mark: &quot;*Add content roots to PYTHONPATH*&quot; and &quot;*Add source roots to PYTHONPATH*&quot;. When I have both unchecked, I can load my module.

So it works now -- **but why**? 

Further questions emerged:

- What are &quot;content roots&quot; and what are &quot;source roots&quot;? And why does adding something to the PYTHONPATH make it somehow break?
- should I uncheck both of those options all the time (so also in the defaults, not only the project specific configurations (left panel of the Run/Debug Configurations dialog)?

PyCharm error: &#39;No Module&#39; when trying to import own module (python script)

I have done a fair amount of googling about this question and most of the threads I&#39;ve found are 2+ years old, so I am wondering if anything has changed, or if there is a new method to solve the issue pertaining to this topic.

As you might know when using IntelliJ (I use 14.0.2), it often autosaves files. For me, when making a change in Java or JavaScript files, its about 2 seconds before the changes are saved.  There are options that one would think should have an effect on this, such as Settings &gt; Appearance &amp; Behavior &gt; System Settings &gt; Synchronization &gt; Save files automatically if application is idle for X sec.  These settings seem to have no effect for me though, and IntelliJ still autosaves, for example if I need to scroll up to remember how a method I am referencing does something.

This is really frustrating when I have auto-makes, which mess up TomCat, or watches on files via Grunt, Karma, etc when doing JS development.  Is there a magic setting that they&#39;ve put in recently?  Has anyone figured out how to turn off auto-save, or *actually* delay it?
