How to Escape Curly-Brackets in f-strings? 😮🔐

Have you ever encountered a situation where you wanted to include curly-brackets in an f-string, but also take advantage of its powerful features? 🤔💭 Don't worry; you're not alone! Many Python developers have struggled with this problem and found themselves scratching their heads. 🤯

Let's take a look at a common issue and some easy solutions to escape those pesky curly-brackets and unlock the full potential of f-strings! 💪🔓

The Problem: Curly-Brackets in f-strings 🚫🤦‍♂️

Consider the following code snippet:

foo = "test"
fstring = f"{foo} {bar}"

You might expect the output to be 'test {bar}', with bar treated as a literal string. However, you'll be greeted with a NameError saying that 'bar' is not defined. 😱❌

Another approach you might try is using a backslash to escape the curly-brackets:

fstring = f"{foo} \{bar\}"

But, alas! This leads to a SyntaxError with a message telling us that "f-string expression part cannot include a backslash". 😫❌

The Solution: Escaping Curly-Brackets ★✔️

Fear not, for there is a solution! 😎🙌

To escape curly-brackets in an f-string, you can simply double them up! 🎉✨ This means that using {{ will produce a single {, and }} will generate a single } in your final string.

Let's modify our previous code snippet to include escaped curly-brackets:

foo = "test"
fstring = f"{foo} {{bar}}"

And voila! The desired output 'test {bar}' will be generated. 🌟💯
