1. List Comprehension Basics: (์ฝ”๋“œ ์˜ˆ์ œ 1)

python
# ์ˆซ์ž ๋ฆฌ์ŠคํŠธ ์ƒ์„ฑ
numbers = [1, 2, 3, 4, 5]

# ์ƒˆ๋กœ์šด ๋ฆฌ์ŠคํŠธ ์ƒ์„ฑ - ๊ฐ ์š”์†Œ์— +1์„ ๋”ํ•œ ๊ฐ’ ๋ฐ˜ํ™˜
even_numbers = [num * 2 for num in numbers if num % 2 == 0 ]

print(even_numbers) # Output: [2, 4, 6]

Explanation: This code creates a new list called even_numbers containing only the even numbers from the original numbers list after adding 1 to each number. even_numbers``numbers– First, we define numbers.
– Next, [num * 2 for num in numbers if num % 2 == 0] does the following: For each num in the numbers list, it checks if the number is even (num % 2 == 0). If it’s even, then that number gets multiplied by 2. – Finally, this result is stored in a new list called even_numbers.
numbers``[num * 2 for num in numbers if num % 2 == 0]``num``numbers``num % 2 == 0``even_numbers #### 2. List Comprehension: (์ฝ”๋“œ ์˜ˆ์ œ 2)

python
fruits = ["apple", "banana", "cherry"]
uppercase_fruits = [fruit.upper() for fruit in fruits]

print(uppercase_fruits) # Output: ['APPLE', 'BANANA', 'CHERRY']

Explanation: This code creates a new list called uppercase_fruits containing the uppercase versions of all the fruits from the original fruits list.
uppercase_fruits``fruits– The list comprehension takes each fruit in the fruits list and converts it to uppercase using .upper(). fruits``.upper()
