Example Programs
Basic Calculations
# Basic arithmetic operations
x = 10
y = 5
print(f"Addition: {x + y}")
print(f"Subtraction: {x - y}")
print(f"Multiplication: {x * y}")
print(f"Division: {x / y}")
print(f"Power: {x ** 2}")
List Operations
# Working with lists
numbers = [1, 2, 3, 4, 5]
print("Original list:", numbers)
numbers.append(6)
print("After append:", numbers)
print("Sum of numbers:", sum(numbers))
print("Maximum:", max(numbers))
print("Minimum:", min(numbers))
String Manipulation
# String operations
text = "Python Programming"
print("Original text:", text)
print("Uppercase:", text.upper())
print("Lowercase:", text.lower())
print("Length:", len(text))
print("Split words:", text.split())
Dictionary Operations
# Working with dictionaries
student = {
"name": "John",
"age": 20,
"grades": [85, 90, 88]
}
print("Student info:", student)
print("Name:", student["name"])
print("Average grade:", sum(student["grades"]) / len(student["grades"]))
# Adding new key-value pair
student["subject"] = "Python"
print("Updated info:", student)
Loops and Range
# Demonstrating loops
print("For loop with range:")
for i in range(5):
print(f"Number: {i}")
print("\nWhile loop:")
count = 0
while count < 3:
print(f"Count: {count}")
count += 1
print("\nLoop through list:")
fruits = ["apple", "banana", "orange"]
for fruit in fruits:
print(f"Fruit: {fruit}")
Functions
# Function examples
def greet(name):
return f"Hello, {name}!"
def calculate_area(length, width):
return length * width
# Testing functions
print(greet("Python Learner"))
print(f"Area of rectangle: {calculate_area(5, 3)}")
# Function with default parameter
def power(base, exponent=2):
return base ** exponent
print(f"Square of 4: {power(4)}")
print(f"4 to power 3: {power(4, 3)}")
