How to escape curly-brackets in f-strings?
Question:
I have a string in which I would like curly-brackets, but also take advantage of the f-strings feature. Is there some syntax that works for this?
Here are two ways it does not work. I would like to include the literal text {bar} as part of the string.
foo = "test"
fstring = f"{foo} {bar}"
NameError: name 'bar' is not defined
fstring = f"{foo} {bar}"
SyntaxError: f-string expression part cannot include a backslash
Desired result:
'test {bar}'
Edit: Looks like this question has the same answer as How can I print literal curly-brace characters in a string and also use .format on it?, but you can only know that if you know that str.format uses the same rules as the f-string. So hopefully this question has value in tying f-string searchers to this answer.
Answers:
Although there is a custom syntax error from the parser, the same trick works as for calling .format on regular strings.
Use double curlies:
>>> foo = 'test'
>>> f'{foo} {{bar}}'
'test {bar}'
