way to create fstring inside a fstring


is it possible to create a fstring inside a fstring?

what i am trying now is to create a dynamic function using eval.

my code is something like this

func_string = ''
for scenario in ['scene1', 'scene2']:
    for aa in ['int', 'ext']:
         func_string += f'''
             def function_{scenario}_{aa}(part):
                 print(f"this is {part}")
           '''


eval(func_string)
function_scene1_int('part1')

running this script will return: this is part1


Solution

  • You can make a factory method like this ...

    def factory(a, b):
        def g(c):
            print(f'this is {c}')
            return f'other stuff using {a}, {b} and {c}'  # if you want to
        return g
    

    then use it like

    >>> f = factory('scene1', 'int')
    >>> msg = f('part1')
    this is part1
    >>> print(msg)
    other stuff using scene1, int and part1
