Python Strings
🎯 한 줄 통찰 (One-line insight)
Python strings are arrays of Unicode characters with no separate character type — a single character is just a length-1 string — so indexing, looping, len(), and membership tests (in/not in) all work directly on them. [S1]
🧠 핵심 개념 (Core concepts)
- Quote flexibility — single and double quotes are interchangeable; nested quotes must differ from the surrounding quote style. [S1]
- Multiline strings — triple double/single quotes preserve embedded line breaks. [S1]
- Strings are arrays — Unicode character arrays; no dedicated char type. [S1]
- Indexing —
a[1]accesses the character at position 1 (0-indexed). [S1] - Looping —
for x in "banana": print(x)iterates characters. [S1] len()— returns string length. [S1]in/not in— membership test for a substring. [S1]
📖 세부 내용 (Details)
- Quotes inside quotes:
print("He is called 'Johnny'"). [S1] - Multiline string:
a = """Lorem ipsum...multiple lines...""". [S1] - Indexing:
a = "Hello, World!"; print(a[1]). [S1] - Length:
print(len(a)). [S1] - Membership:
print("free" in txt),print("expensive" not in txt). [S1]
⚖️ 모순 및 업데이트 (Contradictions & updates)
소스에서 모순되는 정보는 발견되지 않음.
🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 문자열이 배열이라는 성질은 Slicing/Modify/Methods 챕터 전체의 전제가 된다. [S1]
💻 코드 패턴 (Code patterns)
Membership test inside an if statement (Python):
txt = "The best things in life are free!"
if "free" in txt:
print("Yes, 'free' is present.")
