How do you convert a string to base 10 in python?
I've tried to create a simple method to convert a string into a base-10 integer (in Python): Show
It doesn't seem to work. When I tested out 'test' as the string it outputted:

The challenge then becomes decoding. Some web-based Base10 encoders separate each encoded character/byte with a space. I opted to left-pad with a null character which can be trimmed out. I am sure there is plenty of room for optimisation here, but these two functions fit my needs: Encode:
Decode:

How do you convert a string to a real number in Python?To convert, or cast, a string to an integer in Python, you use the int() built-in function. The function takes in as a parameter the initial string you want to convert, and returns the integer equivalent of the value you passed. The general syntax looks something like this: int("str") .
