Python File Handling

🎯 한 줄 통찰 (One-line insight)

open() takes a filename and a mode string combining an action (r/a/w/x) with a format (t/b, both defaulting) — so open("file.txt") is silently shorthand for open("file.txt", "rt"). [S1]

🧠 핵심 개념 (Core concepts)

• open() — the key function for file access; takes filename and mode. [S1]
• Action modes — "r" read (default, errors if missing), "a" append (creates if missing), "w" write (creates if missing, overwrites), "x" create (errors if it already exists). [S1]
• Format modes — "t" text (default), "b" binary (e.g. images). [S1]
• Default shorthand — open("demofile.txt") == open("demofile.txt", "rt"). [S1]

📖 세부 내용 (Details)

• Read mode default: f = open("demofile.txt") is equivalent to f = open("demofile.txt", "rt"). [S1]

💻 코드 패턴 (Code patterns)

open() default mode shorthand (Python):

f = open("demofile.txt")        # same as:
f = open("demofile.txt", "rt")
