re

A regular expression (or RegEx) specifies a set of strings that matches it.

A regex is a sequence of characters that defines a search pattern, mainly for the use of string pattern matching.


The re.search() expression scans through a string looking for the first location where the regex pattern produces a match. 
It either returns a MatchObject instance or returns None if no position in the string matches the pattern.

Code

>>> import re
>>> print bool(re.search(r"ly","similarly"))
True

The re.match() expression only matches at the beginning of the string. 
It either returns a MatchObject instance or returns None if the string does not match the pattern. 
Code

>>> import re
>>> print bool(re.match(r"ly","similarly"))
False
>>> print bool(re.match(r"ly","ly should be in the beginning"))
True
Task 
You are given a string NN. 
Your task is to verify that NN 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 11 decimal value. 
        For example: 
    ✖    ✖ 12. 
    ✔     ✔ 12.0  

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

Input Format

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

Constraints

0<T<100<T<10
Output Format

Output True or False for each test case.

Sample Input

4  
4.0O0
-1.00
+4.54
SomeRandomStuff
Sample Output

False
True
True
False
Explanation

4.0O04.0O0: O is not a digit. 
−1.00−1.00: is valid. 
+4.54+4.54: is valid. 
SomeRandomStuff: is not a number.
