Run a string as method - Python

I want to create some kind of user interface and the user should be able to type the name of the function he wishes to run:

task = input('Programm to run: ')

Once task is defined I want to execute the desired task like:

task()

If for example the desired program is functonthe script shall execute function().

Like said in the comments, you can create a dictionary and run the functions from it:

def func1(): print('I am f1')
def func2(): print('I am f2')
def func3(): print('I am f3')


functions = {'f1': func1, 'f2': func2, 'f3': func3}

x = input('which function:')
functions[x]()  # call the function

Here is another way for doing it globally:

def foo():
    print("foo")


def bar():
    print("bar")


method = input("What method: ")  # ask for method
globals().get(method, lambda: 0)()  # search for global method and execute it

Here's one way:

class Tasks(object):
    def foo(self):
        print('hi')

    def bar(self):
        print('bye')


task = 'foo'

getattr(Tasks(), task)()
