Python, getting ValueError: unexpected '{' in field name when using format variable in a s-CodePudding

This code runs a query on the string exactly as is it should.

bInfoPList = re.findall('{searchString}'.format(searchString = searchString), content, re.M re.S)

This code returns: "ValueError: unexpected '{' in field name"

bInfoPList = re.findall('{searchString}\s*\=\s*\{\{[Pp]lainlist\|.*'.format(searchString = searchString), content, re.M re.S)

The format of the query strings and variable seems identical except for the second one being a longer and having some regex characters. Why doesn't the second one work? What do I need to change?

CodePudding user response：

The mechanism for escaping curly braces is different to what you were trying.

Do this:

bInfoPList = re.findall(f'{searchString}\s*\=\s*{{[Pp]lainlist\|.*', content, re.M   re.S)
