PyCharm Unresolved reference 'print'
PythonPycharmPython Problem Overview
I started to learn python language, and decided to try out PyCharm IDE, which looks really nice. But, whenever I write print it says "Unresolved reference 'print'". I can run the program, but this red-underline is really annoying. How can I fix this?
Python Solutions
Solution 1 - Python
I have had the same problem as you, even though I configured Python 3.4.0 as the project's interpreter and all print's in the code were Python 3 compliant function calls.
I got it sorted out by doing this in PyCharm: > File -> Invalidate Caches / Restart... -> Invalidate and Restart
Solution 2 - Python
If you're in PyCharm and you're getting "Unresolved reference xrange" it's because xrange was removed in Python 3. Range takes over its functionality now. Was working on fast string concat from here:

Solution 3 - Python
This could be related to the version of python you are using. Under python 2.x print is a statement:
print "hello world"
Under python 3, print is now a function call:
print("hello world")
Solution 4 - Python
Same problem, I deleted the .idea and pycache directories in the project directory and everything was fine :)
Solution 5 - Python
Just delete .idea folder from your project directory.
