Proposal: Allow standard python escapes inside curly braces in f-strings. Main point is to make clear visual distinction between text and escaped chars:
# current syntax: print ("\nnewline") print ("\x0aa") # new syntax: print (f"{\n}newline") print (f"{\x0a}a") Currently it is SyntaxError: "SyntaxError: f-string expression part cannot include a backslash" Further, I suggest hex code escapes with a new prefix "\ ", i.e. backslash+space, (this would work in f-strings only obviously) so it could be used instead current variants: \\x, \\u, and \\U without need to include all leading zeros in codes. Consecutive codes can be simply separated by space. Example: # current syntax: print ("\x48\x65\x6c\x6c\x6f\U0001F601") # Hello and a smiley print ("\x0aa") # new syntax: print (f"{\ 48 65 6c 6c 6f 01F601}") print (f"{\ 0a}a") And I personally would like to see an option for decimal charcodes, e.g. with "\." prefix using the same schema as above with hex codes.
