Question

Is there any way to make possible to use functions in your file before you actually declare their body?

The following code doesn’t seem to work:

abc = myFunction

def myFunction():
    print "123"

Thanks

You can’t use the myFunction variable before it’s assigned. Your example code is similar to:

def myFunction():
    print abc
    abc = 123

To do what you want, either re-arrange the order:

def myFunction():
    print "123"

abc = myFunction

Or declare abc as just a proxy:

# Style 1
abc = lambda: myFunction()

# Style 2
def abc():
    return myFunction()

def myFunction():
    print "123"

If your function takes parameters, use *args and **kwargs:

# Style 1
abc = lambda *args, **kwargs: myFunction(*args, **kwargs)

# Style 2
def abc(*args, **kwargs):
    return myFunction(*args, **kwargs)

def myFunction(x):
    print x
