There are several ways to represent integers in Python. In this quick and practical tutorial, you'll learn how you can store integers using int and str as well as how you can convert a Python string to an int and vice versa.
How do I fix “TypeError: can only concatenate str (not ‘int’) to str”? To fix this error, you need to convert the integer to a string using thestr()function or f-strings. This allows Python to concatenate the string and the integer as strings. ...
