Before you start, you may want to read my older articles on binary, octal and hexadecimal numbers:
– Decimal Number vs Binary, Octal and Hexadecimal
And now let’s see how to convert a string representation of a binary, octal or hexadecimal integer to an appropriate integer with the specified base.
Here’s the video version of this article:
We can convert a string representation of a binary, octal or hexadecimal integer to an appropriate integer with the specified base using the following syntax:
int(number_string_representation, base)Here are some examples:
– a binary number
>>> binary_number = "1001"
>>> int(binary_number, 2)
9 – an octal number
>>> octal_number = "10"
>>> int(octal_number, 8)
8 – a hexadecimal number
>>> hexadecimal_number = "F1"
>>> int(hexadecimal_number, 16)
