Python 04: Conditionals and Loops

Conditionals are fundamental for decision-making in your programs. They let your code respond differently to different inputs or situations.

Python 04:  Conditionals and Loops

Today, we're going to tackle two more powerful aspects of Python: Conditionals and Loops.

Understanding Python Conditionals

Conditionals in Python let you make decisions in your code. They are expressed using if, elif, and else statements. Here's a simple example:

In your Python interpreter, type:

x = 10
if x > 5:
    print("x is greater than 5")
else:
    print("x is not greater than 5")

Press Enter. Since x is 10, you'll see the message: "x is greater than 5".

Loops: Python's Way of Doing Repetitive Tasks

Loops allow you to execute a block of code multiple times. The most common types of loops in Python are for and while loops.

For Loop Example:

for i in range(5):
    print(i)

This will print numbers 0 to 4, one number per line.

While Loop Example:

i = 0
while i < 5:
    print(i)
    i += 1

This will also print numbers 0 to 4, one number per line.

Why Learn Conditionals and Loops

  • Conditionals are fundamental for decision-making in your programs. They let your code respond differently to different inputs or situations.
  • Loops are essential for automating repetitive tasks, which is a common requirement in programming.

Today's Challenge Try creating your own conditionals and loops. Experiment with different conditions in if statements and try looping through various ranges using for and while loops. The more you practice, the more comfortable you'll become!
