python help please.

FULLmetallica · 10-21-2009, 07:59 AM

this is my first program and it doesn't work. the myscript.py just opens gedit. here is the code.

PHP Code:


			
#! $ chmod +x myscript.py 

#!/usr/bin/env python

>>>print 'Hello World!'

i am on linux and i believe the first 2 lines makes it executable.

thanks.

You want #!/usr/bin/env python as the top line. Remove the one before it. You need to do the chmod command outside the script to give it executable permissions (no $ before it - that's just a symbol found on many bash prompts).

gedit most likely opens because your system is configured to open files in their default program when entered as the first part of a command line (i.e. a normal file specified like a command).

ok thanks. the file now asks me what to do when i click the file. when i click run in terminal though it opens then closes instantly. my guess is that its reaching the end of the code then closing. how do i fix this?

You should open the terminal, then navigate to where the Python script is. Then you can run it with ./myscript.py

Also, I believe you need to remove the '>>>' in front of the print statement.
