 # Login System

# Ask for a username and password. 

# If both match predefined values, print "Login successful", else show appropriate error messages.

#username : abc

#password : 123

WTP in python - Simple Calculator

 # Simple Calculator

# Ask the user to input two numbers and an operator (+, -, *, /) and perform the corresponding operation.

num1=float(input("Please enter the first number : "))

WTP in python : Input three numbers and print the largest one

# Number Comparison

# Input three numbers and print the largest one.

# Logic Recap:

# First, check if num1 is greater than or equal to both num2 and num3.

# If not, check if num2 is greater than or equal to both num1 and num3.

# If neither is true, then num3 must be the largest.

num1=int(input("Please enter the first number: "))

num2=int(input("Please enter the second number: "))

num3=int(input("Please enter the third number: "))

if(num1 >= num2 and num1 >=num3):

    print(f"{num1} is the largest")

elif(num2>=num1 and num2 >=num3):

    print(f"{num2} is largest ")

else:

    print(f"{num3} is largest ") 

WTP in python - Leap Year Checker

# Leap Year Rules Recap:

# A year is a leap year if:

# It is divisible by 4 and not divisible by 100

# OR

# It is divisible by 400

# For example:

# 2000 → Leap year ✅ (divisible by 400)

# 1900 → Not a leap year ❌ (divisible by 100 but not 400)

# 2024 → Leap year ✅ (divisible by 4 and not 100)

#take input from user 

year = int(input("Please enter the year:  "))

if (year % 4 ==0 and year % 100 !=0) or (year % 400 == 0):

    print(f"{year} is a leap year")

else:

    print(f"{year} is not a leap year")

WTP in python - Grade Calculator

# Grade Calculator

# Input a percentage and print the grade:

# A (90–100)

# B (80–89)

# C (70–79)

# D (60–69)

# F (below 60)

percent=int(input("Please enter the percent: "))

if (percent>=90 and percent<=100):

    print(f"{percent} , Your Grade is A")

elif(percent>=80 and percent<=89):

    print(f"{percent} , Your Grade is B")

elif(percent>=70 and percent<=79):

    print(f"{percent} , Your Grade is C")

elif(percent>=60 and percent<=69):

    print(f"{percent} , Your Grade is D")

elif ( percent >0 and percent<60):

    print(f"{percent} , Your Grade is F")

else:

    print("Invalid Number") 

WTP in python - Age Group Classifier

Age Group Classifier

Input a person's age and classify them as:

Child (0–12)

Teen (13–19)

Adult (20–59)

Senior (60+)

#take the input from user
