Call function in other files by using globals()

I am trying to using globals to call the function whose name matches the string. For example:

def abc():
    print('test')

globals()['abc']()  # -> test

but if abc is in another file, how should I call this function.

import file_that_have_abc as imp
globals()['imp.abc']()

will not work because it will call function name 'imp.abc' in recent file instead.

You just need to use the globals() call to access the variables in your current module. For other modules, just use the name you imported the module with - and to retrieve functions/classes/variables from there from their names as strings, use the getattr function.

For example:

import math
func = `sin`

getattr(math, func)(0)

Use getattr for accessing members of the module:

func = getattr(globals()['file_that_have_abc'], 'abc')
func()

of course, you can drop the globals here if you don't need to look up the module too.
