Use a string to call function in Python [duplicate]

by

This does not exactly answer your question, but maybe it helps nevertheless:

As mentioned, eval should be avoided if possible. A better way imo is to use dictionary unpacking. This is also very dynamic and less error prone.

Example:

def fullName(name = "noName", family = "noFamily"):
    return name + family

functionList = {'fullName': fullName}

function = 'fullName'
parameters = {'name': 'Foo', 'family': 'Bar'}

print functionList[function](**parameters)
# prints FooBar

parameters = {'name': 'Foo'}
print functionList[function](**parameters)
# prints FoonoFamily
