python实现进度条代码

我可以提供一些基本的 Python 代码，用于实现进度条：import timeimport sys # for printing current progressbar def progressbar(it, prefix="", size=60): count = len(it) def _show(_i): x = int(size*_i/count) sys.stdout.write("%s[%s%s] %i/%i\r" % (prefix, "#"*x, "."*(size-x), _i, count)) sys.stdout.flush() _show(0) for i, item in enumerate(it): yield item _show(i+1) sys.stdout.write("\n") sys.stdout.flush()# Example usage of progressbar:for i in progressbar(range(100), "Computing: ", 40): time.sleep(0.1)
