Introduction to programming using Python exercise solutions

1. Variables and Data Types

Variables are used to store data, and Python supports various data types such as integers, floats, strings, and booleans.

# Example: Variables and Data Types
age = 25 # Integer
height = 5.9 # Float
name = "Alice" # String
is_student = True # Boolean

print(f"Name: {name}, Age: {age}, Height: {height}, Is Student: {is_student}")

2. Basic Operations

Python supports basic arithmetic operations like addition, subtraction, multiplication, and division.

# Example: Basic Operations
a = 10
b = 3

sum_result = a + b
diff_result = a - b
prod_result = a * b
div_result = a / b # Division always returns a float
mod_result = a % b # Modulus operation

print(f"Sum: {sum_result}, Difference: {diff_result}, Product: {prod_result}, Division: {div_result}, Modulus: {mod_result}")

3. Control Structures >> Introduction to programming using Python exercise solution

Control structures like if-else statements and loops (for and while) are used to control the flow of the program.

# Example: If-Else Statement
number = 7

if number % 2 == 0:
print(f"{number} is even")
else:
print(f"{number} is odd")

# Example: For Loop
for i in range(5):
print(f"Iteration {i}")

# Example: While Loop
count = 0
while count < 5:
print(f"Count: {count}")
count += 1

4. Functions

Functions are reusable blocks of code that perform a specific task.

# Example: Function Definition and Call
def greet(name):
return f"Hello, {name}!"

message = greet("Alice")
print(message)

5. Lists and Dictionaries

Lists and dictionaries are common data structures in Python.

# Example: List
fruits = ["apple", "banana", "cherry"]
fruits.append("date")
print(f"Fruits: {fruits}")

# Example: Dictionary
person = {
"name": "Alice",
"age": 25,
"is_student": True
}
print(f"Person: {person}")

6. File I/O

Reading from and writing to files is a common task in programming.

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

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

7. Exception Handling

Handling exceptions is crucial for building robust programs.

# Example: Exception Handling try:
result = 10 / 0
except ZeroDivisionError as e:
print(f"Error: {e}")
finally:
print("This block always executes")

8. Classes and Objects

Python is an object-oriented programming language, and classes are used to create user-defined data structures.

# Example: Class and Object
class Person:
def __init__(self, name, age):
self.name = name
self.age = age

def greet(self):
return f"Hello, my name is {self.name} and I am {self.age} years old."

# Creating an object of the Person class
person = Person("Alice", 25)
print(person.greet())

Conclusion

These examples cover some of the basic concepts in Python programming. As you progress, you’ll encounter more advanced topics such as modules, libraries, and frameworks. For further reading, I recommend the official Python documentation and tutorials on platforms like Real Python.
