Python Programming: Key Concepts from Punjab College Certificate

Introduction:
I recently completed the Python programming course from Punjab College, Pakistan, where I learned the fundamentals of Python and practical coding techniques. In this article, I will share key learnings including variables, loops, functions, and data structures like lists, dictionaries, and tuples.

Body:
Variables & Data Types:
Python variables can store different types of data: integers, floats, strings, booleans.

Example:
name = "Saad"
age = 20
is_student = True

Control Structures & Loops:
Conditional statements (if, elif, else) help make decisions in code. Loops (for and while) repeat tasks efficiently.
Example:

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

count = 0
while count < 5:
print("Count:", count)
count += 1

Functions:
Functions organize code into reusable blocks.
Example:

def greet(name):
return f"Hello, {name}!"

print(greet("Saad"))

Lists:
Ordered collection of items, mutable, can store multiple data types.
Example:

fruits = ["apple", "banana", "cherry"]
fruits.append("orange")
print(fruits)

Tuples:
Ordered collection, immutable, useful for fixed data.
Example:

coordinates = (10, 20)
print(coordinates)

Dictionaries:
Key-value pairs, very useful for storing structured data.
Example:
student = {"name": "Saad", "age": 20, "course": "Python"}
print(student["name"])

Basic File Handling:
Read and write files to store data.
Example:
with open("data.txt", "w") as f:
f.write("Hello, Python!")

Conclusion:
Completing the Python course was a great learning experience. My tip for beginners: practice loops, functions, and data structures by building small projects. This strengthens problem-solving skills and makes programming concepts easy to remember.
