In Python programming, an identifier refers to a name given to variables, functions, classes, modules, or other objects. Identifiers must adhere to specific rules and conventions. The first character of an identifier must be a letter (a-z, A-Z) or an underscore (_). Subsequent characters can be letters, digits (0-9), or underscores. Identifiers cannot be one of the reserved keywords in Python. Capitalization matters, as total and Total are treated as distinct identifiers. There is no maximum length for an identifier.
Examples of identifiers include:
gobi
isStudent
_rollno
_name
Reserved words, also known as keywords, cannot be used as identifiers or variable names. These keywords have predefined meanings in Python and cannot be reassigned or overridden. The list of keywords includes: False, None, True, and, as, assert, async, await, break, class, continue, def, del, elif, else, except, finally, for, from, global, if, import, in, is, lambda, nonlocal, not, or, pass, raise, return, try, while, with, and yield.
