Python Strings Modify

🎯 한 줄 통찰 (One-line insight)

Common string transformations — case conversion, whitespace trimming, substring replacement, and splitting into a list — are built-in methods, each returning a new string/list rather than mutating in place. [S1]

🧠 핵심 개념 (Core concepts)

• upper() / lower() — case conversion. [S1]
• strip() — removes leading/trailing whitespace. [S1]
• replace(old, new) — replaces a substring with another. [S1]
• split(separator) — splits into a list of substrings at each separator occurrence. [S1]

📖 세부 내용 (Details)

• Upper/lower: a.upper(), a.lower(). [S1]
• Strip: a = " Hello, World! "; print(a.strip()) # "Hello, World!". [S1]
• Replace: a.replace("H", "J"). [S1]
• Split: a.split(",") # ['Hello', ' World!']. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — split()의 결과가 리스트라는 점은 이후 Python Lists 챕터로 직접 연결된다. [S1]

💻 코드 패턴 (Code patterns)

Split a string into a list (Python):

a = "Hello, World!"
print(a.split(","))  # ['Hello', ' World!']
