![]() If you need compatibility with ancient versions of Python, you can either use gmpy (which does include a fast, completely general int-to-string conversion function, and can be built for such ancient versions – you may need to try older releases since the recent ones have not been tested for venerable Python and GMP releases, only somewhat recent ones), or, for less speed but more convenience, use Python code – e.g., for Python 2, most simply: import stringĭigs = string.digits + string.ascii_lettersįor Python 3, int(x / base) leads to incorrect results, and must be changed to x // base: import stringĭigs = string.digits + string. How to convert an integer to the shortest url-safe string in Python?.Integer to base-x system using recursion in python.Python elegant inverse function of int(string, base).I want to allow bases other than 2, 8, 16 I want a general solution that can be called the same way for different bases Those functions are not available on older versions of Python, with which I need compatibility with (2.2) When you use the int() function to convert a string to an int, you can specify the number system as the second argument. I know about the functions bin, oct, hex, but I cannot use them for a few reasons: However, I feel like I must be missing something. This is an easy function to write: in fact it's easier than describing it in this question. The function name/argument order is unimportant.įor any number x and base b that int() will accept. Convert base using int () in Python In this example, we used the int () function to convert the base of a number from Binary, Octal, and Hexadecimal to a Decimal integer. ![]() I want some function int2base(num, base), such that: int(int2base(x, b), b) = x I want to perform the inverse: creation of a string from an integer, This done by simply passing a string that has the other base representation of a decimal number and the base value as the second argument. The first method sets the base value on the int () function to 16 (hex). Use the syntax print(int('STR')) to return the str as an int, or integer. This function takes two parameters: the initial string and the optional base to represent the data. For any number x and base b that int() will accept. To convert a string to integer in Python, use the int() function. ![]() I want some function int2base(num, base), such that: int(int2base(x, b), b) x The function name/argument order is unimportant. I want to perform the inverse: creation of a string from an integer, i.e. Python allows easy creation of an integer from a string of a given base via int(str, base). Method One Using Base 16 to Convert a Hex to Integer. Python allows easy creation of an integer from a string of a given base via. ![]()
