Question

The question is to consider the following function definition:

def read_value_type(prompt='Enter a Boolean> ', convert=bool):
    val = input(prompt)
    return convert(val)

as a multiple choice:

1. val = read_value_type(convert=bool, prompt='Enter a boolean>')
2. val = read_value_type(prompt='Enter a float> ')
3. val = read_value_type()

and it is asked which of the above are valid calls to read_value_type?

Since none display errors, and seem to be reading, I was wondering whether the three of them would call the function or not?

Answer 1

All of them. But second will return bool, not float.
