Can you concatenate str and int in Python?In most other programming languages, if we concatenate a string with an integer (or any other primitive data types), the language takes care of converting them to a string and then concatenates it. However, in Python, if you try to concatenate a string with an integer using the + operator, you will get a runtime error.

Why can't I concatenate in Python?There are a few programming languages, like JavaScript, which allow you to concatenate strings and integers together. In Python, you cannot do this. If you want to concatenate a string and an integer, you've got to convert the integer to a string first before you concatenate it to a string.
