Running Python programmes

[David]

I am an absolute beginner and am working through the book Python Programming for the Absolute Beginner by Michael Dawson. Everything is fine except if I run a scripted programme, or one I have downloaded, and then run another one, the second one will not run, I just get the >>> in the interactive window. I have to exit Python and start again, when the second programme then runs fine.

Any suggestions much appreciated.

David,

Perhaps you could show a very small program, maybe 3 or 4 lines, that
illustrates the problem.

Python 3? Windows? Using Idle?

You leave out a lot of details, including what version of Python, what
OS, how you're running these "programmes" and what you mean "will not
run."

For example, if you're on Linux, running Python 3.3, and you're running
these "programmes" from the bash prompt,

$ python3.3 prog1.py
some results

$ python3.3 prog2.py
some other results

I'd be amazed if you even saw the >>>> prompt.

Maybe you're inadvertently running Python with either the '-i' switch or with the PYTHONINSPECT environment variable set?
When you do that, your script will launch an interactive prompt after it completes.


C:\Python27>echo print "hello" > hello.py

C:\Python27>python hello.py
hello

C:\Python27>python -i hello.py
hello

C:\Python27>set PYTHONINSPECT=1

C:\Python27>python hello.py
hello
