When I first started learning Python, the one thing I wanted more than anything was to be able to use template strings, like had gotten used to in JavaScript.

language = "JavaScript"
string = `this is a string literal in ${language}`

For some reason, I couldn’t find a decent article telling me how to do them.

Then on Sunday, when I asked ChatGTP to generate a piece of code for me, I was struck by something in the output.

url = f"https://login.microsoftonline.com/{TENANT_ID}/oauth2/v2.0/token"

So I asked ChatGTP what the ‘f’ meant, and it told me about ‘f-strings’ for ‘formatted string literals` in python, which is exactly what I was I was looking for.

So here you are. If you want to use template strings in python, then prefix the string with an f, and you’re done!
