    is it me or just an error that the following code doesn't work for string(0) (='0')

    I still dont get why it doesn't print out anything nor True, nor False. just nothing printed out for '0'

    import re

T = int(input())
for _ in range(T):
    string = str(input())
    try:
        if float(string):
            if re.match('([\\+\\-]?\d*\\.\d+)', string):
                print(True)
    except Exception:
        print(False)
