Ever tried to combine a number with some text and got a Python TypeError? That’s because you can’t mix data types. To fix this, you need to perform an integer to string in Python. This guide breaks down the easiest ways to do it, so you can stop running into those annoying errors.
The most straightforward way to convert an integer (or a float) into a string is with the built-in str() function. This is your go-to for simple, direct conversions.
It works just like it sounds: you pass a number into the str() function, and it gives you a string back.
Syntax:
Examples:
You’ll use the str() function a ton, especially when you need to print a number or write it to a file. It’s the simplest and most reliable method.
If you’re combining numbers with text, f-strings (formatted string literals) are your new best friend. They’re way cleaner and more readable than using the str() function with plus signs.
To create an f-string, you just put an f before the opening quote. Then, you can embed variables directly inside the string using curly braces {}. Python automatically converts any number inside the braces to a string for you.
Syntax:
Why f-strings are so great: They make your code easy to read, especially when you have a lot of variables in one string. For any new code, this is the method you should be using.
While str() and f-strings are the way to go, you might see a couple of other methods in older code. It’s good to know they exist, but you shouldn’t rely on them for new projects.
The .format() method: This was the standard way to format strings before f-strings. It’s still used, but it’s not as concise.
The % operator: This is an even older method borrowed from the C programming language. It’s generally considered outdated and is not recommended.

Can you convert a string back to an integer?
Yes, you can! The reverse operation uses the int() and float() functions. Just make sure the string you’re converting is a valid number, or you’ll get a ValueError.
How do I convert a list of integers to a list of strings?
You can use a list comprehension, which is a concise way to create new lists.
