Welcome back, Pythoneers!
This issue is all about making your code smarter and more adaptable. Get ready to discover how Python's conditional statements (if
and else
) empower your programs to make choices and respond to different situations.
What are Conditional Statements?
Imagine your code is like a choose-your-own-adventure book. Conditional statements are the decision points where you get to choose which path the story (or your program) takes. In Python, we use if
and else
to create these branching paths.
Basic if/else
Statements
Let's start simple. An if
statement checks if a condition is true. If it is, the code block indented below it gets executed.If the condition is false, the code moves on to the else
block (if there is one). Also dont forget to put “:” in your if and else
age = 12
if age < 18:
print("You are a minor.")
else:
print("You are an adult.")
Multiple Conditions with elif
Sometimes, you have more than two possible paths. That's where elif
(short for "else if") comes in. You can use multiple elif
statements to check for additional conditions.
grade = 87
if grade >= 90:
print("Excellent work!")
elif grade >= 80:
print("Great job!")
elif grade >= 70:
print("You passed!")
else:
print("Keep trying!")
Challenge Time: The Decision Maker
Your Mission: Create a Python program that asks the user a series of questions and gives different responses depending on their answers. Get creative! You could build a quiz, a personality test, or even a simple choose-your-own-adventure story.
Python Pro Tip:
Use conditional statements to check for errors or unexpected input in your programs. This helps make your code more robust and reliable.
