In Python, variable names are case-sensitive.

Question

BlackTom AI · Accepted Answer

Consider the statement in question: 'In Python, variable names are case-sensitive.'
Option True: This is accurate. Python distinguishes between uppercase and lowercase letters in identifiers. For example, the variables myVar and myvar would refer to different objects, and assigning to one does not affect the other.
Option False: This is incorrect. If variables were not case-sensitive, writing myVar and myvar would refer to the same identifier, leading to overwriting or unpredictable behavior. The Python language specification and practical usage demonstrate that case sensitivity is a fundamental feature of identifiers, affecting scope, binding, and lookup.
Additional clarification: Case sensitivity impacts how you declare, reference, and manipulate variables, functions, and other identifiers. Being aware of this avoids errors like NameError or unexpected overwrites when similar names with different capitalization are used in code.
