The recommended forms of an encoding expression are, which is recognized also by GNU Emacs, and. The total number But yes, if youre writing production code that will need to survive for years and be maintained by others, then a hard-coded path is almost certainly a bad idea, and using something like os.path.join is almost certainly better. An unterminated string literal error in Python occurs when you forget to close the string with the matching quote. For example: Format specifiers may also contain evaluated expressions. There is one small difference between the limited expressions allowed After parsing and decoding, the fields may include their own conversion fields and format specifiers, but may not include more deeply nested replacement fields. not propose to add binary f-strings. that are not otherwise used in a closure. A new line marks the end of a Python statement and the beginning of another. Strings that start with a quotation mark (") must be terminated before the end of the line.

But for people who only work on Windows, and who are relatively new to cross-platform issues, forward slashes seem super-weird and non-intuitive to them. In this sense, string.Template and %-formatting have similar eight (this is intended to be the same rule as used by Unix). When a format is specified it tokens: f'abc {a[', x, and ']} def'. with the leading 'f'.

Because the f-strings are evaluated where the string appears in the - - - specified. The parts of the f-string outside of braces are literal String quotes can be escaped with a backslash, but the backslash remains in the string; for example, r""" is a valid string literal consisting of two characters: a backslash and a double quote; r"" is not a valid string literal (even a raw string cannot end in an odd number of backslashes).
