问题 How do I format 1000000 to 1.000.000 in Python? where the '.' is the decimal-mark thousands separator. 回答1: If you want to add a thousands separator, you can write: >>> '{0:,}'.format(1000000) '1,000,000' But it only works in Python 2.7 and higher.

问题 C++14 introduced the concept of digit separators into literals, along the lines of 3'141'592'653'589 . Now this is a great feature for readable code but I was wondering whether it allowed quotes before the numeric portion of a 0x/0b -type literal. It seems to me that: unsigned int topThreeBits = 0b'1110'0000; unsigned int hexNum = 0x'dead'beef; is more readable than the one without a leading separator: unsigned int topThreeBits = 0b1110'0000; unsigned int hexNum = 0xdead'beef; because it

问题 While clang compiles the following line, g++ 6.1 complains about the digit separator (see live example on Coliru): auto time = 01'23s; Which compiler, if any, is correct according to the C++14 standard (N3796)? Otherwise, is allowing digit separators (§2.14.2) just an implementation detail in the user-defined literals (§2.14.8) of the <chrono> library (§20.12.5.8)? IMHO it should be not, since these literals are defined on unsigned long long parameters. I remember Howard Hinnant using 10'000s
