问题 What do parameters -u , -m mean and what do they do? for example: python -u my_script.py or python -m my_script.py Where can I read about them? 回答1: -u is used to force stdin , stdout and stderr to be totally unbuffered, which otherwise is line buffered on the terminal -m searches sys.path for the named module and runs the corresponding .py file as a script. An example would be timeit module. The command python -m timeit "python script" would return the time taken for the script to execute.

问题 This is a follow up to this question so if you need to see the Register class please refer to that question. Now based on the supplied answer I have written a function to do just that. I have 2 versions of the function one that will store the results back into the original and one that will return a copy. Here are my functions: template<std::uint64_t N> void reverseBitOrder( Register<N>& reg ) { auto str = reg.register_.to_string(); std::reverse(str.begin(), str.end()); auto x = vpc::Byte(str
