Problem Statement

Create a `User` class. Its `__init__` should accept `**kwargs`. Check if ’email’ is in `kwargs`. If not, set `self.email` to ‘Not Provided’. Print ‘Email: [email]’.

Input Format

A single string representing an email, or the string 'NONE' to simulate missing.

Output Format

Print the processed email.

Constraints

None

Sample Input

admin@edcret.in

Sample Output

Email: admin@edcret.in

Explanation

Using **kwargs allows flexible object instantiation and requires safe handling of missing keys.

Starter Code

class User:
    # Define __init__ using **kwargs
    pass

if __name__ == '__main__':
    inp = input().strip()
    if inp == 'NONE':
        u = User()
    else:
        u = User(email=inp)
