I have a variable which is an int, and I want to be able to compare the individual digits so I thought making it into a list would be best, since I can just do int(number[0]), int(number[1]) to easily convert the list element back into int for digit operations.

In Python, you can convert a Python int to a string using str (): >>> >>> str(10) '10' >>> type(str(10)) <class 'str'> By default, str () behaves like int () in that it results in a decimal representation: >>> >>> str(0b11010010) '210' In this example, str () is smart enough to interpret the binary literal and convert it to a decimal string. no means the data types should not be cast at all. int assumes the literal integer to be decimal: The string representation of an integer is more flexible because a string holds arbitrary text data: Each of these strings represent the same integer.
