Question

How do I execute all the code inside a python file so I can use def’s in my current code? I have about 100 scripts that were all written like the script below.

For a simple example, I have a python file called:

D:/bt_test.py

His code looks like this:

def bt_test():
    test = 2;
    test += addFive(test)
    return(test)

def addFive(test):
    return(test+5)

Now, I want to from a completely new file, run bt_test()

I’ve tried doing this:

def openPyFile(script):
    execfile(script)

openPyFile('D:/bt_test.py')
bt_test()

But this doesn’t work.

I’ve tried doing this as well:

sys.path.append('D:/')
def openPyFile(script):
    name = script.split('/')[-1].split('.')[0]
    command = 'from  ' + name +  ' import *'
    exec command

openPyFile('D:/bt_test.py')
bt_test()

Does anyone know why this isn’t working?

Here’s a link to a quicktime video that will help explain what’s happening.

In addition to Ned’s answer, __import__() might be useful if you don’t want the file names hardcoded.

Update based on the video.

I don’t have access to Maya, but i can try and speculate.

cmds.button(l='print', c='bt_press()') is where the issue seems to lurk. bt_press() is passed as a string object, and whatever way the interpreter uses to resolve that identifier doesn’t look in the right namespace.

1) Try passing bt_press() with the module prepended: cmds.button(l='print', c='bt_test.bt_press()')

2) See if you can bind c directly to the function object: cmds.button(l='print', c=bt_press)

Good luck.
