function converter to print in binary format. There is also not a binary conversion specifier in glibc (GNU Project's implementation of the C standard library) normally. But if we want to do so we have to create custom conversion types to print the binary format by using existing format ...

Once expressions in a format specifier are evaluated (if necessary), format specifiers are not interpreted by the f-string evaluator. Just as instr.format(), they are merely passed in to the__format__()method of the object being formatted. 小结 控制一个字符串格式,可以分为2部分 被控制的输...
