Python is not like other script language. Its strongly against the variable types mismatch. For example at other scripting language, you can easily assign an integer into a string type of variable. Or concat them easily with concatination operators.
But at python, you can not concat a string with an integer until you are making them both string. If you try to do that, you'll get an error like below.
TypeError: cannot concatenate 'str' and 'int' objects
You must need to convert your integer into string. If you are a new at Python, that will be difficult for you to find the simple str() function that will convert your integer to string. Here is a code which using str() function to do that.
integer = 10
string = "ten"
output = string + str(integer)
