For Python 3.x, use `input()`. For Python 2.x, use `raw_input()`. Don&#39;t forget you can add a prompt string in your `input()` call to create one less print statement. `input(&quot;GUESS THAT NUMBER!&quot;)`. 

I have a problem using Laravel 5. When I run &quot;php aritsan migrate&quot;, I got this error

    **************************************

    Do you really wish to run this command? [y/N] y

    [PDOException]

I could run the application, but when database connection needed, I got this error

    PDOException in Connector.php line 55:

I am using Mocha, Chai, Karma, Sinon, Webpack for Unit tests.

I followed this link to configure my testing environment for React-Redux Code.

I&#39;m a seventh grade programmer so I may be missing a lot of things in this program, but for my coding club my instructor asked us to make a guess the number game. I have very limited knowledge on this subject, since I&#39;ve only attended four classes. Anyway, when I run this program in Python IDLE 3.5 this is what it says:

    Traceback (most recent call last):
    File &quot;C:\Users\morrris\AppData\Local\Programs\Python\Python35-32\guess_that_number.py&quot;, line 7, in &lt;module&gt;
    name= raw_input()
    NameError: name &#39;raw_input&#39; is not defined

I tried changing the code, but it seems to not like the raw_input().

I have an image that is 6400 &#215; 3200, while my screen is 1280 x 800. Therefore, the image needs to be resized for display only. I am using Python and OpenCV 2.4.9.
According to [OpenCV Documentation][1], 

&gt; If you need to show an image that is bigger than the screen resolution, you will need to call namedWindow(&quot;&quot;, WINDOW_NORMAL) before the imshow.

That is what I am doing, but the image is not fitted to the screen, only a portion is shown because it&#39;s too big. I&#39;ve also tried with cv2.resizeWindow, but it doesn&#39;t make any difference.


    import cv2
    cv2.namedWindow(&quot;output&quot;, cv2.WINDOW_NORMAL)        # Create window with freedom of dimensions
    # cv2.resizeWindow(&quot;output&quot;, 400, 300)              # Resize window to specified dimensions
    im = cv2.imread(&quot;earth.jpg&quot;)                        # Read image
    cv2.imshow(&quot;output&quot;, im)                            # Show image
    cv2.waitKey(0)                                      # Display the image infinitely until any keypress

OpenCV &amp; Python - Image too big to display

I see patterns like

    def __init__(self, x, y, z):
        ...
        self.x = x
        self.y = y
        self.z = z
        ...

quite frequently, often with a lot more parameters. Is there a good way to avoid this type of tedious repetitiveness? Should the class inherit from `namedtuple` instead?


How do I avoid the &quot;self.x = x; self.y = y; self.z = z&quot; pattern in __init__?

What is the most efficient way to map a function over a numpy array? The way I&#39;ve been doing it in my current project is as follows:

    import numpy as np 

    x = np.array([1, 2, 3, 4, 5])

    # Obtain array of square of each element in x
    squarer = lambda t: t ** 2
    squares = np.array([squarer(xi) for xi in x])

However, this seems like it is probably very inefficient, since I am using a list comprehension to construct the new array as a Python list before converting it back to a numpy array.

Can we do better?

I work with conda environments and need some pip packages as well, e.g. pre-compiled wheels from [~gohlke][1].

At the moment I have two files: `environment.yml` for conda with:

    # run: conda env create --file environment.yml
    name: test-env
    dependencies:
    - python&gt;=3.5
    - anaconda

and `requirements.txt` for pip which can be used after activating above conda environment:

    # run: pip install -i requirements.txt
    docx
    gooey
    http://www.lfd.uci.edu/~gohlke/pythonlibs/bofhrmxk/opencv_python-3.1.0-cp35-none-win_amd64.whl

Is there a possibility to combine them in one file (for conda)?
