Python 조건 및 루프 이해: 초보자 가이드

Mastering conditions and loops in Python is essential for controlling program flow and repeating tasks efficiently. Ready to dive in? Let's break it down step-by-step!

1. If-Else Conditions

The if-else statement lets your program make decisions. If a condition is True, a block of code runs; otherwise, the else block executes.

Example: Check Voter Eligibility by Age

age = 20
if age >= 18:
    print("You are eligible to vote.")
else:
    print("You are not eligible to vote.")

2. Elif: Handling Multiple Conditions

The elif statement allows you to check multiple conditions sequentially. If the first condition is False, Python checks the next one.

Example: Finding the Greatest Number

num1, num2, num3 = 5, 10, 3
if num1 > num2 and num1 > num3:
    print("num1 is the greatest")
elif num2 > num3:
    print("num2 is the greatest")
else:
    print("num3 is the greatest")

3. For Loops

The for loop repeats a block of code for a specific number of iterations. Ideal when you know how many times you want to loop through a sequence.

Example: Looping with a Range

for i in range(1, 11):
    print(i)

4. While Loops

The while loop continues to execute a block of code as long as a specified condition is True. Useful when the number of iterations is unknown.

Example: While Loop Counting to 10

i = 1
while i
