User-validation checker(DAY-1)

Problem Statement The program asks for four things:

• Full Name
• Email ID
• Mobile Number
• Age
• It checks each one based on certain rules. If everything’s good, you get “User Profile is VALID.” If not, you get “User Profile is INVALID.

Validation Rules

• Full Name: Has to have at least two words. Can’t start or end with a space.
• Email ID: Needs at least one @ and one . Can’t start with @.
• Mobile Number: Exactly 10 digits, only numbers, and shouldn’t start with 0.
• Age: Must be over 18 and no more than 60.

Algorithm

• Ask for your full name, email, mobile number, and age.

• Check the full name for the right number of spaces and no leading or trailing spaces.

• Check the email for @ and . and make sure it’s not starting with @.

• Check the mobile number for length, digits, and starting digit.

• Make sure the age is in the right range.

• Print out if the profile is valid or not.

  Smart ID & Credential Validator(DAY-2)

  Problem Statement

This program is part of a university Smart Registration System. It validates student credentials before approving an account.

The program takes:

• Student ID
• Email ID
• Password
• Referral Code

If all inputs are valid, it prints APPROVED. Otherwise, it prints REJECTED.

Validation Rules

• Student ID must follow the format CSE-XX
• Email ID must contain @, ., and end with .edu
• Password must be at least 8 characters, start with an uppercase letter, and contain a digit
• Referral Code must follow the format REF##@

Approach

• Read all inputs from the user.
• Validate each input using string operations and conditions.
• Check all rules one by one.
• Print APPROVED if all validations pass, else REJECTED.

Constraints

• Strings and conditional statements only
• No loops, lists, regex, or external libraries

Student Performance Analyzer(DAY-3)

Description

This program analyzes student marks using basic Python concepts. Marks are stored in a list, updated using a personalized rule, and then classified into performance categories.

Concepts Used

• for loop

• list

• string

-conditional statements

Classification Rules

• 90–100 → Excellent

• 75–89 → Very Good

• 60–74 → Good

• 40–59 → Average

• 0–39 → Fail

• < 0 or > 100 → Invalid

Personalized Logic

Personalization is based on the length of my name:

If the digit is odd, all marks are decreased by 1

If the digit is even, all marks are increased by 1

This personalization changes the final classification.

Output

Displays category for each mark

Counts total valid students

Counts total failed students

Prints final summary

sample test case output

enter no.of student marks:3

enter marks of student in subject 1:23

enter marks of student in subject 2:34

enter marks of student in subject 3:45

Enter your registration number last digit: 4

marks after updation: [22, 33, 44]

22 ->fail

33 ->fail

44 ->average

total valid students are : 3

total fail students are: 2

Student Data Filter Program(DAY-4)

Problem Statement

This program processes a mixed list of numbers and strings. It separates them into two different lists using a for loop. It also applies one personalized logic rule.

Base Logic

• If element is number → add to numberList

• If element is string → add to stringList

• Ignore empty strings ("")

• Count total numbers

• Count total strings

Personalization Used

Option B – Name Length Logic

My Name: Mounish Name Length: 7

If name length is even → Remove the first element from both lists

If name length is odd → Remove the last element from both lists

Since my name length is odd, the last element is removed from both lists.

Output Format

• Display final Number List

• Display final String List

• Display Total Numbers

• Display Total Strings

Concepts Used

• List

• For loop

• Conditional statements

• String handling

Rules Followed

• No dictionary

• No set

• No filter() or map()

• No list comprehension

• No hard-coded output
