functional programming - How to call Python functions dynamically

I have this code:

fields = ['name','email']

def clean_name():
    pass

def clean_email():
    pass

How can I call clean_name() and clean_email() dynamically?

For example:

for field in fields:
    clean_{field}()

I used the curly brackets because it's how I used to do it in PHP but obviously doesn't work.

How to do this with Python?

If don't want to use globals, vars and don't want make a separate module and/or class to encapsulate functions you want to call dynamically, you can call them as the attributes of the current module:

import sys
...
getattr(sys.modules[__name__], "clean_%s" % fieldname)()
