Using string.format with "{" already in string python

Question

The string already has '{' inside it. Now I want to use python format method.

a = "{foo{}}"
b = a.format("bar")

result should be {foobar}

There are many ways to solve the problem but I want to know is there a way to skip first '{'.

In Python=>3.6 you can use f-strings and just like in `format` you use double braces. — Mick_, Jun 07 '18 at 13:16

To have a regular brace, use it twice in a format string.

>>> "{{foo{}}}".format("bar")
'{foobar}'

You could use the %x syntax as well:

a = "{foo%s}"
b = a % 'bar'

Which will return '{foobar}' just fine.

FYI: to print % in a string you would use %%.
