This decorator works by storing the time just before the function starts running in line 10 and just after the function finishes in line 12. The runtime of the function is then the difference between the two, calculated in line 13. You use time.perf_counter(), which does a good job of...
Many processes in nature involve randomness in one form or another. 自然界中的许多过程都以这样或那样的形式涉及随机性。 Whether we investigate the motions of microscopic molecules or study the popularity of electoral candidates,we see randomness, or at least apparent randomness, almost everywhere. 无...

When the Python interpreter reads this line, it will set the encoding that it uses to read the rest of the file. This comment must appear in one of the first two lines of the file to be valid.Another difference between MATLAB and Python is in how inline documentation is written. In ...
