The in operator is used to check if a value exists in a sequence or collection.

• The in operator returns a boolean value (True or False).

• It can be used with strings, lists, tuples, and dictionaries.

• Example: 'a' in 'apple' will return True.

• Example: 3 in [1, 2, 3, 4] will return True.

• Example: 'cat' not in {'dog': 1, 'cat': 2} will return False.

Python has many built-in functions that can be used without importing any module.

• Built-in functions are pre-defined functions in Python.

• They are always available and can be used directly in the code.

• Examples include print(), len(), range(), type(), etc.

Literals are fixed values in Python code, such as numbers, strings, and booleans.

• Literals are used to represent data in a program.

• Numeric literals can be integers, floats, or complex numbers.

• String literals are enclosed in quotes, either single or double.

• Boolean literals are either True or False.

• Examples: 42 is an integer literal, 'hello' is a string literal, True is a boolean literal.

Keywords are reserved words in Python that have a specific meaning and cannot be used as variable names.

• Keywords are used to define the syntax and structure of the language.

• Examples of keywords include 'if', 'else', 'for', 'while', 'def', 'class', 'import', 'try', 'except', 'finally', 'and', 'or', 'not', 'in', 'is', 'None', 'True', and 'False'.

• Using a keyword as a variable name will result in a syntax error.

• Keywords are case sensitive and must be written in lowercase.
