printf-style string formatting has a number of quirks, and leads to less readable code than using str.format calls or f-strings. In general, prefer the newer str.format and f-strings constructs over printf-style string formatting.

Note The formatting operations described here exhibit a variety of quirks that lead to a number of common errors (such as failing to display tuples and dictionaries correctly). Using the newer formatted string literals, the str.format() interface, or template strings may help avoid these errors. Each of these alternatives provides their own trade-offs and benefits of simplicity, flexibility, and/or extensibility.
