  • Learn Python in Tamil | Python Basics | How to use Conditional Statements if ,elif, else

    More Examples :

    1. Basic if-else Statement:

    number = 10
if number > 5:
 print("The number is greater than 5.")
else:
 print("The number is 5 or less.")

    2. Multiple Conditions with elif:

    marks = 85
if marks >= 90:
    print("Grade: A")
elif marks >= 75:
    print("Grade: B")
elif marks >= 50:
    print("Grade: C")
else:
    print("Grade: F")

    3. Nested if Statements:

    age = 25
if age >= 18:
    if age >= 21:
        print("Eligible for a full license.")
    else:
        print("Eligible for a provisional license.")
else:
    print("Not eligible for a license.")

    4. Using Logical Operators:

    score = 85
attendance = 90
if score > 80 and attendance > 85:
    print("You passed with good standing!")

    5. Error Handling with Conditionals:

    try:
    age = int(input("Enter your age: "))
    if age >= 18:
        print("You are eligible to vote.")
    else:
        print("You are not eligible to vote.")
except ValueError:
    print("Please enter a valid number.")

  • Python – Functions Examples

    Example 1 : 

    # Define a function
def greet():
    print("Hello, World!")

# Call the function
greet()

    Output : 

    Hello, World!

    Example 2 : 

    # Define a function with parameters
def greet(name):
    print(f"Hello, {name}!")

# Call the function with an argument
greet("Alice")

    Output : 

    Hello, Alice!

    Example 3 : 

    # Define a function with two parameters
def add(a, b):
    return a + b

# Call the function with arguments
result = add(3, 4)
print(result)

    Output : 

    7

    Example 4 : 

    # Define a function that returns a value
def square(x):
    return x * x

# Call the function and store the result
result = square(5)
print(result)

    Output : 

    25

    Example 5 : 

    # Define a function that returns multiple values
def get_name_and_age():
    name = "Alice"
    age = 30
    return name, age

# Call the function and unpack the result
name, age = get_name_and_age()
print(name, age)

    Output : 

    Alice 30

    Example 6 : (Area of Circle using Functions)

    def areaofcircle(r):
    answer=3.14*r
    return answer

radius=int(input("Enter Radius Value"))
ans=areaofcircle(radius)
print ("Answer",ans)

    Output : 

    Enter Radius Value 1
