Detect Floating Point Number

You are given a string N.
Your task is to verify that N is a floating point number.

In this task, a valid float number must satisfy all of the following requirements:

> Number can start with +, - or . symbol.
For example:
✔+4.50
✔-1.0
✔.5
✔-.7
✔+.4
✖ -+4.5

> Number must contain at least 1 decimal value.
For example:
✖ 12.
✔12.0  

> Number must have exactly one . symbol.
> Number must not give any exceptions when converted using float(N).

Input Format

The first line contains an integer T, the number of test cases.
The next T line(s) contains a string N.

Constraints

• 0 < T < 10

Output Format

Output True or False for each test case.

Sample Input 0

4
4.0O0
-1.00
+4.54
SomeRandomStuff

Sample Output 0

False
True
True
False

Explanation 0

4.000: O is not a digit.
-1.00: is valid.
+4.54: is valid.
SomeRandomStuff: is not a number.

Solution Implementation

import re
class Main():
    def __init__(self):
        self.n = int(input())
        for i in range(self.n):
            self.s = input()
            print(bool(re.match(r'^[-+]?[0-9]*\.[0-9]+$', self.s)))           
if __name__ == '__main__':
    obj = Main()
