Python Tokens

Python Tokens are individual units in a program. The following are the types of Tokens:

  1. Keywords
  2. Identifiers
  3. Literals


Keywords are reserved words used in programming languages. The compiler/ interpreter already knows these names, so you cannot use them as variable names.

Identifiers in Python

Identifiers in Python are used for naming of variables, functions and arrays. Do not use keywords as identifiers.

An identifier begins with a letter A to Z or a to z or an underscore (_) followed by zero or more letters, underscores and digits (0 to 9). That means, it is a combination of character digits and underscore.

Python Identifiers


Literals are the values assigned to each constant variable. Python has the following literals:

  • String Literals: Enclose text in quotes. Can use both single as well as double quotes. Use triple-quotes for multi-line string.
  • Numeric Literals: Includes int, long, float and complex.
  • Boolean Literals: Can have either True or False values

Let us now see examples of Literals in Python:
