You need to double the {{ and }}:
>>> x = " {{ Hello }} {0} "
>>> print(x.format(42))
' { Hello } 42 '
Here's the relevant part of the Python documentation for format string syntax:
Answer from Greg Hewgill on Stack OverflowFormat strings contain “replacement fields” surrounded by curly braces
{}. Anything that is not contained in braces is considered literal text, which is copied unchanged to the output. If you need to include a brace character in the literal text, it can be escaped by doubling:{{and}}.

Python 3.6+ (2017)
In the recent versions of Python one would use f-strings (see also PEP498).
With f-strings one should use double {{ or }}
n = 42
print(f" {{Hello}} {n} ")
produces the desired
{Hello} 42
If you need to resolve an expression in the brackets instead of using literal text you'll need three sets of brackets:
hello = "HELLO"
print(f"{{{hello.lower()}}}")
produces
{hello}

Curly braces in string without f
How do I use text.format() when the text has curly braces from HTML CSS?
python's print(f"{format}") issues with nested curly braces. My need is for automating some latex formulas which needs a ton of nested curly braces like: $$\binom{10}{0}\cdot 0.25^{0}\cdot0.75^{(10-0)}$$

Hey everyone, I have a quick question regarding the use of curly brackets in strings, but I couldn’t find an answer online.
So I know that using f-strings, curly braces inside the string will get replaced with the variable/expression inside. If I want to include the literal { } characters in the string, however, I just have to double them {{}}.
But what happens if I’m not using an f-string and I include the curly braces in the string? I tried this and it prints the literal symbols, but in VSCode, the expression in the code including the braces turns blue. What does this mean?
Edit: thanks everyone for your responses!
Solved:
The issue below is solved by adding 3 curked brackets like {{{x}}} or even {{({x}-{y})}}
(where x-y is meant to show as an latex equation)
I want to print latex friendly code from python which means printing curly braces, but I'm running into a few issues regarding the print formating of python [ the f"{string}" thing].
Anyone knows how to correctly do it? Or there is no support yet for nested curly braces on python?
The link for my code can be seen here: https://trinket.io/python3/08dd26b052
I'll also paste the relevant part of the code here so you can glance at it real quicky:
The "hack" I had to do was using "<" and ">" since they don't mess with the print statement.
Then I have to open up any text editor that has an "replace all" button and change all every angled brace for their respective curled brace (which is tedious, but less tedious than typing 5 similar latex equations)
import matplotlib.pyplot as plt
from math import comb
height = []
n=10
for k in range (6):
print(f"$$\\binom<{n}><{k}>\\cdot 0.25^<{k}>\cdot0.75^<({n}-{k})>$$")Hey guys, I am currently trying to POST data to an airtable database, but I cant get my variables to work, either f-string or .format. I tried double curlies at the beginning and end, and like this case double curlies for the variables... What am I doing wrong? 😅
Thanks a lot!
data = '{\n "fields": {\n "Entry number": "1",\n "email adress": "{{}}",\n "password": "{{}}"\n },\n "typecast": true\n}'.format(user_name, user_password)For "escaping" one typically use \, as in \{ and \}. However, for the typewriter font, you might be interested in \string{ and \string}:
\documentclass{article}
\begin{document}
Compare \texttt{\string{\string}} to \verb|{}| and \texttt{\{\}}
\end{document}
\string provides similar output to \verb, but is allowed in moving arguments.
Use a short verbatim environment, or load the fontenc package.
\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
\texttt{\{ Braces \}} \{ Braces \} \verb+ { Braces }+
\end{document}
The braces in the middle version are 'ordinary' text; the ones you need are on the left
and the right. Without fontenc, the first method will give the wrong symbols. This answer explains what's going on.
