Using Pyhton 2.7 and Ubuntu 15.10
I faced an annoying issue when using raw_input in a python console of some IDES like ninja-ide or genay (console plugin). They cast a "EOFError: EOF when reading a line" and don't allow to write.
Meanwhile developing a *.py file, the execution is correct and don't fail. Python, as executing from terminal, doesn't fail as well as console using IDLE.
Any solution? Thanks. I couldn't find exactly this issue neither in StackOverflow nor Internet.

I am new to Python and recently installed Python 3.6 on Windows 10. When I try to open IDLE, Python's IDE, I keep getting a message saying that it can not establish a subprocess. I have tried uninstalling and installing several times. I have seen several forums which say that there could be a .py file that is in the directory that is messing up IDLE. This is not my case, as I have not even been able to start using Python and I do not have a firewall either. Can someone tell me how I can get IDLE to work?
In this answer I collected together 9 possible reasons for the message, as reported in various SO answers.
If you try to start IDLE from a command line (Command Prompt or PowerShell)
> python -m idlelib # idlelib.idle for 2.x
one might get a helpful error message.
I work with over 30 Python developers and without fail when this happens they were behind a proxy / vpn. Turn off your proxy / vpn and it will work. Must have had this happen hundreds of times and this solution always worked.
For some reason, whenever I try to open a python script that has around ~450 lines of code, IDLE's windows simply appears empty and when I try to run it doesn't run anything either... However, if I try to run a smaller program it works for some reason. Does anybody know how I am able to run a python script on my Mac besides IDLE or how to fix the IDLE window being blank whenever I open a file?
To learn how to run Python Python programs on a Mac, read Chapters 1 and 4 of Python Setup and Usage. Running from an IDLE editor is just one way.
IDLE uses the tkinter module which wraps the tcl/tk GUI framework. Did you read and follow the instructions of how to replace the buggy tcl/tk that Apple supplies? Read the entire page before starting! Ignoring this page is the most common reason people have problems with IDLE on the Mac. There are a few others, but I do not remember one that matches your description.
I have a Raspberry Pi and I'm attempting to create a Python script. However the issue is that I'm unable to run the script from the Terminal, it throws syntax errors yet the same code works just fine in the Python 3.5.3 Shell.
I'm trying the simplest thing such as a printand I've tried various ways with the parentheses and quotation marks, yet no luck with executing the script in the terminal.
I'll include a simple Imgur link of a screenshot, showing how the code is successfully executed in the Shell but not in the terminal.

The code:
print ("test")
Any assistance is greatly appreciated in advance!
The error was that your terminal didn't know that the code you tried to execute was python, therefore it tried to execute it with the bash interpreter.
Adding the correct shebang to specify the use of the python interpreter fixed the problem.
#!/usr/bin/env python
print("test")
you can execute python scripts, i.e. the script boa.py from terminal by python boa.py
I installed python 2.7.10 on my 1and1 linux hosting service about 8 months ago (using instructions from http://geeksta.net/geeklog/python-shared-hosting/) and everything was working fine (I had a daily cron job that would call my python script). But recently,my python script stopped working and it appears that the call to python itself is the culprit, rather than the python code. Whenever I type 'python' into the command line in the 1and1 unix ssh session now, i get the following error message
"-bash: /kunden/homepages/26/xxxxxxxxxx/htdocs/python27/bin/python: No
such file or directory"
It's been awhile since I installed things, but I don't believe I had this issue previously. I'm trying to figure out why it's not working and what I can do to get it fixed. It appears that calling python isn't working properly (which would affect my script as well).
Any help with getting this working would be greatly appreciated.
when you type python, system find it in /kunden/homepages/26/xxxxxxxxxx/htdocs/python27/bin/python, but there is no such a file in fact.
what you need to do is trying to locate your python binary executable file, and alias your python to your file
I ended up just reinstalling python 2.7 again and it works again. Not sure why it stopped working before.
Now I can type "python" in the command line and it starts the Python console.
I wrote the code mentioned in the example section of this page in the shell of IDLE, and it didn't execute and returned "SyntaxError: multiple statements found while compiling a single statement". What is wrong with it?
I have used pyDes some time ago (Python 2.7, Windows XP) and this worked fine for me.
Which Python are you using, and which is your OS?
IMHO, your syntax error is about a few indentation problems == missed tabs\spaces.
Check spaces and tabs in your code, rewrite code manually
I used IDLE 2.7.5+ and the code produced encrypted text and ran just fine. IDLE 3.3.2+ does not work with pyDes for some reason, at least on my OS: Ubuntu Linux.
