How can I convert a string to either int or float with priority on int?

Question

I couldn\'t find another answer when I wanted this, so I thought I would post my own solution for anyone else and also get corrections if I\'ve done something wrong.

Answer 1

def int_float_none(x):
    # it may be already int or float 
    if isinstance(x, (int, float)):
        return x
    # all int like strings can be converted to float so int tries first 
    try:
        return int(x)
    except (TypeError, ValueError):
        pass
    try:
        return float(x)
    except (TypeError, ValueError):
        return None

Function above for any object passed will return int or float conversion or None.
