How Do I Convert a Binary String to an Integer in Python?

Encoding Binary Numbers in Python

Converting a binary number to an integer in Python requires manipulating its base representation. In this case, a base-2 binary number must be transformed into a decimal equivalent.

To accomplish this, Python provides the int() function with an optional base argument. The base parameter specifies the numeral system used for the input string. For binary conversion, the base is set to 2.

Implementation:

binary_number = '11111111'
decimal_number = int(binary_number, 2)

This operation yields the decimal equivalent of the binary number:

print(decimal_number)
# 255

The int() function effectively converts the binary string '11111111' into an integer by interpreting its digits in order of their base-2 representation, resulting in the decimal number 255.
