Fundamental Concepts in Python

Python uses character sets like ASCII and Unicode to define valid characters that can be used in programs. Identifiers are names given to variables, functions, and classes that must start with a letter and can contain letters, numbers, and underscores. Variables reference values in memory and are assigned using the = operator. Python supports different data types like integers, floats,...

Identifiers are names given to variables, functions, and classes that must start with a letter and can contain letters, numbers, and underscores. Variables reference values in memory and are assigned using the = operator. Python supports different data types like integers, floats, strings, and more. Expressions involve values, variables, and operators to evaluate to a value. Input and output statements are used to provide data to programs and display results.
