'f-string: unmatched '(' in line with function call
I'm trying to use f-strings in python to substitute some variables into a string that I'm printing, and I'm getting a syntax error. Here's my code:
print(f"{index+1}. {value[-1].replace("[Gmail]/", '')}")
I only started having the problem after I added the replace. I've checked plenty of times and I'm certain that I'm not missing a parenthesis. I know that there are plenty of other ways to accomplish this, some of which are probably better, but I'm curious why this doesn't work.

Your problem is double quotes inside double quotes. This one should work correctly:
print(f"{index+1}. {value[-1].replace('[Gmail]/', '')}")
Out of scope but still I do not advise you to use replace inside f-string. I think that it would be better to move it to a temp variable.

Seems like this does not work
x = 'hellothere'
print(f"replace {x.replace("hello",'')}")
error
print(f"replace {x.replace("hello",'')}")
^
SyntaxError: f-string: unmatched '('
Try this instead
x = 'hellothere'
print(f"replace {x.replace('hello','')}")
single quotes 'hello'
output is
replace there

Another way to do some string formatting (which in my opinion improves readability) :
print("{0}. {1}".format(index+1,
value[-1].replace("[Gmail]/", "")))

I had the same issue,change all the double quote within the parenthesis to single quotes.It should work
eg from
print( f" Water : {resources["water"] } " )
to
print( f" Water : {resources['water'] } " )
