Dynamically create functions from Json

[Larz60+]

the best way to create a command driven execution is to use a dictionary, here's a simple example:

class SoftwareCommands:
    def __init__(self):
        self.commands = {
            'func_a': self.func_a,
            'func_b': self.func_b,
            'willy nilly': self.willy_nilly
        }
    
    def func_a(self):
        print("\nHi, I'm func_a")
    
    def func_b(self):
        print("\nHi, I'm func_b")
    
    def willy_nilly(self):
        n = 0
        while n < 10:
            print('n: {}'.format(n))
            n += 1


def main():
    command = None
    sc = SoftwareCommands()
    while command != 'quit':
        command = input("Enter a command, quit to end: ").strip().lower()
        if command in sc.commands:
            sc.commands[command]()

if __name__ == '__main__':
    main()

outout:

Output:
Enter a command, quit to end: func_a

Hi, I'm func_a
Enter a command, quit to end: willy nilly
n: 0
n: 1
n: 2
n: 3
n: 4
n: 5
n: 6
n: 7
n: 8
n: 9
Enter a command, quit to end: quit
