Literals
It is defined as any data stored in a variable. This data can be String literals are enclosed in single or double
quotes. For example,
"Hello"
'Python'
• Numeric literals: They can be integer, float or complex. For example,

Punctuators
Punctuators are special symbols used in Python to organise statements and expressions. Most commonly used
punctuators in Python are:
' " # \ () {} [] @ , : . =
Operators
Operators are special symbols used to perform mathematical, logical and relational operations on variables and
values. The variables or values on which the operators work are called operands. Some commonly used operators
in Python are arithmetic operators, relational operators, logical operators and augmented assignment operators.
Arithmetic Operators
Arithmetic operators are used to perform mathematical operations on variables and values.
Following arithmetic operators are provided by Python:
Name Symbol Purpose Example Output
2 + 4 6
Addition + Adds two values. 2.0 + 4 6.0
"hi" + "all" "hiall"
Subtracts second value form the 6 – 2 4
Subtraction –
first value. 6.0 – 2 4.0
2 * 3 6
Multiplication * Multiplies two values. 1.5 * 2 3.0
"Hi" * 3 HiHiHi
4 / 2 2.0
6.0 / 2 3.0
Division / Divides two values.
6 / 2.0 3.0
11 / 2 5.5
