Operators
Operators are used to perform operations on variables and values. Let us study in detail about the commonly
used operators in Python.
Arithmetic Operators
Arithmetic operators are used to perform mathematical operations on variables and values. Arithmetic operators
used in Python are:
Name Symbol Purpose Example Output
Exponential ** First number raised to the 2**5 32
power of the second number. 3.5**3 42.875
Multiplication * Multiplies two values 5*4 20
Note: String * int repeats string 3.5*2 7.0
that many times. "Bye"*2 ByeBye
Division / Divides two values. 9/3 3.0
6.0/3 2.0
6/3.0 2.0
17/2 8.5
Floor division // Divides the first number with 17//3 5
the second and returns the -18//5 -4
whole number adjusted left to
the number line. 23//6 3
