Python int() function

The int() function in Python is used when we need to convert any specified value into an integer value. For example:

x = 12.43
print(int(x))
x = "132"
print(int(x))

The output will be:

12
132

Python int() function syntax

The syntax of the int() function in Python is:

int(val, base)

where val refers to a number or a string that has to be converted into an integer object, and base refers to the base of the returned number.

Note: The default value of val is 0, whereas the default value of base is 10. The default value of base is 10, which indicates that the returned value will be in the decimal number system.

Python int() function example

Here is an example of the int() function in Python:

print(int('101', 2))
print(int('71', 8))
print(int('123', 10))
print(int('A', 16))

The output will be:

5
57
123
10

because:

Note: Providing no parameter to int() gives 0.

Note: Most of the time, the int() function is used to get integer input using int(input()), because the input() function treats every user input as a string by default.
