Syntax

int(literal, base)

Parameters

Converting different literals into integer data type

In the example below, int() function is used to convert integer literal, float literal and string literal into an integer data type.

x = int(1)
print(x)

y = int(10.55)
print(y)

z = int('100')
print(z)

The output of the above code will be:

1
10
100
