Example:

PI = 3.14159  # Constant PI represents the value of pi

Example in Python:

age = 18
if age >= 18:
    print("You are eligible to vote.")
else:
    print("You are not eligible to vote.")

Example using a for loop:

for i in range(5):
    print("Iteration:", i)

Example:

def add(a, b):
    return a + b

Example:

text = "Hello, World!"
print(text.lower())       # Outputs: hello, world!
print(text[0:5])          # Outputs: Hello

Example of reading from and writing to a file:

# Writing to a file
with open("example.txt", "w") as file:
    file.write("Hello, file!")

# Reading from a file
with open("example.txt", "r") as file:
    content = file.read()
    print(content)  # Outputs: Hello, file!

Example:

is_raining = True
is_cold = False
print(is_raining and is_cold)  # Outputs: False

Example:

result = (10 + 5) * 2  # Outputs: 30

Example: Below is a Python example of a simple procedural program that simulates basic banking actions, such as checking a balance and making a deposit or withdrawal.

# Define constants and variables
balance = 1000.00  # Initial balance

# Function to display the balance
def check_balance():
    print("Your current balance is:", balance)

# Function to deposit an amount
def deposit(amount):
    global balance
    balance += amount
    print(f"Deposited ${amount}. New balance is: ${balance}")

# Function to withdraw an amount
def withdraw(amount):
    global balance
    if amount > balance:
        print("Insufficient funds!")
    else:
        balance -= amount
        print(f"Withdrew ${amount}. New balance is: ${balance}")

# Main program loop
while True:
    print("\\n--- Banking Menu ---")
    print("1. Check Balance")
    print("2. Deposit")
    print("3. Withdraw")
    print("4. Exit")

    choice = int(input("Enter your choice: "))

    if choice == 1:
        check_balance()
    elif choice == 2:
        deposit_amount = float(input("Enter amount to deposit: "))
        deposit(deposit_amount)
    elif choice == 3:
        withdraw_amount = float(input("Enter amount to withdraw: "))
        withdraw(withdraw_amount)
    elif choice == 4:
        print("Exiting program.")
        break
    else:
        print("Invalid choice. Please try again.")

Explanation of the Example:

• Variables: balance is used to store the current bank balance.
• Functions: Separate functions (check_balance, deposit, withdraw) are used to handle different banking actions.
• Selection: The if-elif-else statements allow the user to select from different menu options.
• Iteration: The while loop keeps the program running until the user decides to exit.
