Write a python code or algorithm that validate a student Reg No. It must start with two letters followed by four digits example : CK1234.

An error will be flagged If a user enters an input that is not within the specified conditions.

Kindly help me out with this.

I am still new to python, but i think you would utilize the

input() - to get user input

try.....except....finally / or if else - to validate user input

isalpha() & isdigit() in the try block to validate the alphabet and digit part of the input




Modified - This should give you an idea of the step to take. I have not tested this and don't know if the code used is correct.

Reg = input("Please enter your Reg Number: "

if Reg[:1].isalpha() and Reg[2:5].isdigit(): #can also add another condition here to check if the length of input ==5 (and len(Reg) == 5)
print("Reg Number Valid!"
else:
print("Not valid, You have to figure a way to loop the process." #Can use the while before the if/else to loop



edited again. i think it is cleaner to use while for validation

Reg = input("Please enter your Reg Number: "

while not Reg[:1].isalpha() and Reg[2:5].isdigit() and len(Reg) == 5: #can try isnumeric() if isdigit doesn't work
Reg = input("Error: Re-enter correct Reg number: "

Thank you for taking out time to respond to this. I'll try the suggested approaches and get back to you.

This should help

while True:
regn = input('enter reg nunber: ').strip()
print(regn[:2], regn[2:])
if regn[:2].isalpha() and regn[2:].isnumeric() and len(regn) == 6:
print("beta pikin"
break
continue

See below. Tested and working.

Good. I have entered the codes as is: here is the attached code and the result and the result I get each time I entered a reg no

Check your code. After "while not" should be "Reg" not "Re".

If you read the error message, you should always identify the problem.

Also, maybe it is just my eyes, but the "Reg" under "while not" the space is too much. Should press "tab" once.

I think using regular expression is well suited for this kind of task

Hopefully programming section starts to seem more like stackoverflow. Nice work

Nice..
Started my programming journey,August,it’s been easy-going so far but the only issues I’m having at the moment is loops..I guess with time,I’ll master!

Wow! It worked! I appreciate your persistence and invaluable contributions. Thanks a lot.
