calling a function and argument in an input

[jefsummers]

The extremely dangerous way to do it is the exec() function. You are opening up your machine to the user, but here's an example

cmd = input('What do you want to do?')
print(f'You want to {cmd}')
exec(cmd)

Output:
What do you want to do?print('foo bar')
You want to print('foo bar')
foo bar
