CONSTANTS OR LITERALS
Constants are fixed values that do not change during the execution of a program. Literals are the
type of constant. Literals refer to any number, text and other information that represents a value.
Python supports the following literals:
Literals Example
String literals “hello”, ‘12345’
Integer literals 0, 1, 2, -1, -2
Long literals 89675
Floating-point literals 3.14
Complex literals 12j
Boolean literals True or False
Special literals None
Unicode literals u“hello”
List literals [5,6,7]

▶ Identifiers refer to variables, functions and list.
▶ A token is the smallest element of a Python program that is meaningful to the interpreter.
OPERATORS
Operators are special symbols that are used to perform specific operation on operands and give
a meaningful result. Operands are the data involved in the mathematical operation, and may be
stored in variables and constants.
