Python convert string to int different base code#
On my own PC, this code was able to complete 10 million iterations using the input range, 0-9999, and base, 36, in consistently below 5 seconds. Python str () is a built-in function, which is used to convert integer (int) to string. Num //= base # move to next digit to the left There are two python built-in methods, which are commonly used to convert string to int and int to string python as shwon below: Python int () is a built-in function, which is used to convert the string to an integer value. def int2base(num, base, abc="0123456789abcdefghijklmnopqrstuvwxyz"): Simply put, it works by first taking an integer, base, and an optional accompanying string of numerals, then calculating each digit of the converted integer beginning with the least significant. Believe it or not, the following is some ported and modified Scratch code I wrote nearly three years ago to see just how quickly I could convert from denary to hexadecimal. Looks like this might be my time to shine. Structure.append(acceptable_digit if acceptable_digit = 2 and = 2 and <= 36") Raise InvalidBaseError("Invalid value: ".format(number))Īcceptable_digit = int(number / (base ** floor(logarithm))) If 1 >= base or base >= len(_alphanumerals) or not floor(base) = base: #getvalue is also a personal function to replicate int(number, base) from math import log, ceil, floorĬlass FloatConvertError(ValueError): passĬlass IncorrectBaseError(ValueError): passĭef getbase(number, base=2, frombase = 10): I had once written my own function with the same goal but is now embarrassingly complicated. You can pass in the string as the first argument, and specify the base of the number if it is not in base 10. This function takes the first argument as a type String and second argument base. > str_base(734,symbol_space).rjust(6,symbol_space) To convert string to int (integer) type use the int () function. > str_base(734,symbol_space).rjust(0,symbol_space) After that, the literaleval() function finds the base of that string and converts the. If you want to padd with the propper zero symbol you can use symbol_space = 'abcdest' Here, the literaleval() function is applied to the initial string. That lead's to following output > str_base(13,'01')
> other math if you use binary, oct or hex -> diff in unsigned & signed values def str_base(number, base):
I also ignored negativ values just for shortness and the fact that's mathematical incorrect I'd like to come up with a little change (I used) to convert decimal to a base of symbolspace It helped me a lot to prototype an algortithm I had to implement in C
