Python Variable Names

🎯 한 줄 통찰 (One-line insight)

A legal Python variable name must start with a letter or underscore, contain only alphanumerics/underscores, avoid Python keywords, and is always case-sensitive — with Camel/Pascal/Snake case as the three common multi-word naming conventions. [S1]

🧠 핵심 개념 (Core concepts)

• Naming rules — must start with a letter or _; cannot start with a number; only alphanumeric characters and underscores allowed; case-sensitive; cannot be a Python keyword. [S1]
• Legal examples — myvar, my_var, _my_var, myVar, MYVAR, myvar2. [S1]
• Illegal examples — 2myvar (starts with digit), my-var (hyphen), my var (space). [S1]
• Camel Case — myVariableName (first word lowercase, rest capitalized). [S1]
• Pascal Case — MyVariableName (every word capitalized). [S1]
• Snake Case — my_variable_name (words separated by underscores). [S1]

📖 세부 내용 (Details)

• Legal names: myvar = "John", _my_var = "John", myVar = "John". [S1]
• Illegal names: 2myvar, my-var, my var. [S1]
• Three multi-word conventions: Camel/Pascal/Snake case, each solving readability differently. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — Snake Case는 Python 커뮤니티의 사실상 표준 변수/함수 명명 관례로 이후 모든 예제에서 암묵적으로 따라진다. [S1]

💻 코드 패턴 (Code patterns)

Three naming conventions (Python):

myVariableName = "John"   # Camel Case
MyVariableName = "John"   # Pascal Case
my_variable_name = "John" # Snake Case
