The %s specifier converts the object using str(), and %r converts it using repr(). For some objects such as integers, they yield the same result, but repr() is special in that (for types where this is possible) it conventionally returns a result that is valid Python syntax, which could be used to unambiguously recreate the … Read more
Edit: I can’t reproduce the problem. Everything works as expected when I use the following code compiled with gcc: The output of gcc –version is as follows: gcc (Debian 4.7.2-5) 4.7.2

The format specifiers for String formatting in Swift are the same as those in Objective-C NSString format, itself identical to those for CFString format and are buried deep in the archives of Apple Documentation (same content for both pages, both originally from year 2002 or older): https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFStrings/formatSpecifiers.html https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/Strings/Articles/formatSpecifiers.html But this documentation page itself is incomplete, … Read more
It has no special meaning. It just inserts a $ character: Sometimes a dollar is just a dollar. You also linked to the wrong documentation; the formatting syntax documented there only applies to the format() function and the str.format() method. You want to look at the printf-style String Formatting section instead.
that doesn’t work. If you specify positions, you have to do it through the end: In your case, best is to leave python treat that automatically:
In Python 2 (and Python 3) you can do: Basically % is like printf or sprintf (see docs). For Python 3.+, the same behavior can also be achieved with format: For Python 3.6+ the same behavior can be achieved with f-strings:
You can declare it yourself quite easily: This is assuming that String.format is defined elsewhere. e.g. in Microsoft Ajax Toolkit : http://www.asp.net/ajaxlibrary/Reference.String-format-Function.ashx
bytes objects do not have a __format__ method of their own, so the default from object is used: It just means that you cannot use anything other than straight up, unformatted unaligned formatting on these. Explicitly convert to a string object (as you did by decoding bytes to str) to get format spec support. You … Read more
One trick is to solve this:
