Python Guide - Road to Mastery (Course 2)

Welcome Back to Python Basics!

We're glad to have you back in this course. Let's continue learning and improving your Python skills!

5. Conditional Statements

Conditional statements allow a program to make decisions based on conditions. Python uses if, elif, and else for decision-making.

age = 18
if age >= 18:
    print("You are an adult.")
elif age > 12:
    print("You are a teenager.")
else:
    print("You are a child.")

Explanation:

  • If age = 18, the output will be: You are an adult.
  • If age = 15, the output will be: You are a teenager.
  • If age = 10, the output will be: You are a child.

6. Loops

Loops help execute a block of code multiple times without repetition.

# For loop example
for i in range(5):
    print("Iteration:", i)

Output:

Iteration: 0
Iteration: 1
Iteration: 2
Iteration: 3
Iteration: 4

# While loop example
count = 0
while count < 3:
    print("Count is", count)
    count += 1

Output:

Count is 0
Count is 1
Count is 2

7. Functions

Functions help organize code into reusable blocks, making it efficient and readable.

def greet(name):
    return "Hello, " + name + "!"

print(greet("Alice"))

Output: Hello, Alice!

8. Try It Yourself

Use the interactive Python editor below to practice your own code:

9. Python Quiz

Test your knowledge with this quick quiz.

Question 1: What will be the output of if 5 > 3: print("Yes")?

Question 2: What will be the output of for i in range(3): print(i)?

10. Challenge Task

Write a Python function that finds the largest of three numbers:

def find_largest(a, b, c):
    # Your code here
    pass

How This Works:

  • Conditional Statements: Used for decision-making in Python.
  • Loops: Automate repetitive tasks with for and while loops.
  • Functions: Reusable blocks of code that make programs modular.
  • Interactive Editor: Try out your own Python code.
  • Quiz: Test your knowledge with interactive questions.
  • Challenge Task: Improve your problem-solving skills.
