Please show your love and support by sharing this post. This could be useful, for example, if a variable with a number can be of different types (such as binary, octal, hexadecimal, etc.).

the base) to the int() method, which would make it infer the value: If the binary string has 0b (or 0B) radix prefix, then you may also specify 0 as the second argument (i.e. 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:
