    This prints True for '0' when I submit code

    print(True if re.match(r"^[-+\.]?\d*\.\d*$", input()) else False)

    This prints False for '0' when I submit code

    print(True if re.match(r"^[-+\.]?\d*\.?\d*$", input()) else False)

    what am I missing here?

    It should be the reverse, i.e. second statement above should be "True" (see regex101.com link) https://regex101.com/r/dIOXFe/1

    import re 
N = int(input())

for _ in range(N):
    print(True if re.match(r"[+-]?[0-9]*\.[0-9]+$", input()) else False)

    T = int(input())

    for n in range(1, T+1):

    skip_rest = False
string_value = input()

try:
    float(string_value)
except ValueError:
    print(False)
    continue

split_string_value = list(string_value)

count = 0
Is_alpha = 0
for j in string_value:

    if j == ".":
        if j == string_value[-1]:
            print(False)
            skip_rest = True
            break
        count += 1
    if j.isalpha() is True:
        Is_alpha += 1

if skip_rest is True:
    continue
elif count== 1 and Is_alpha == 0:
    print(True)
else:
    print(False)

    x = int(input()) lst = [input() for i in range(x)] for i in lst: if i == '0': print("False") try: if float(i): print("True") except: print("False")
