ValueError: invalid literal for int() with base 2: '0o11111' Specifying an invalid binary number would raise the following error: This also works with binary strings that have the " 0b" (or " 0B") binary radix prefix: In Python, you can use the int() method (with a base 2 as the second argument) to convert a binary string to its integer equivalent, for example, like so:
