Validating UID in Python | HackerRank Solution

Hello coders, today we are going to solve Validating UID HackerRank Solution in Python.

Task

ABCXYZ company has up to 100 employees.
The company decides to create a unique identification number (UID) for each of its employees.
The company has assigned you the task of validating all the randomly generated UIDs.

A valid UID must follow the rules below:

• It must contain at least 2 uppercase English alphabet characters.
• It must contain at least 3 digits (0 – 9).
• It should only contain alphanumeric characters (a – z, A – Z & 0 – 9).
• No character should repeat.
• There must be exactly 10 characters in a valid UID.

Input Format

The first line contains an integer T, the number of test cases.
The next T lines contains an employee’s UID.

Output Format

For each test case, print ‘Valid’ if the UID is valid. Otherwise, print ‘Invalid’, on separate lines. Do not print the quotation marks.

Sample Input

2
B1CD102354
B1CDEF2354

Sample Output

Invalid
Valid

Explanation

B1CD102354: 1 is repeating → Invalid
B1CDEF2354: Valid

Solution – Validating UID in Python

# Enter your code here. Read input from STDIN. Print output to STDOUT
import re

for _ in range(int(input())):
    u = ''.join(sorted(input()))
    try:
        assert re.search(r'[A-Z]{2}', u)
        assert re.search(r'\d\d\d', u)
        assert not re.search(r'[^a-zA-Z0-9]', u)
        assert not re.search(r'(.)\1', u)
        assert len(u) == 10
    except:
        print('Invalid')
    else:
        print('Valid')
