在Python中实现控制台中的文本进度条 使用python以相反的顺序读取文件 Python中的整数缓存有什么用? 在Python中实现控制台中的文本进度条 # Print iterations progress def printProgressBar (iteration, total, prefix = '', suffix = '', decimals = 1, length = 100, fill = '█'): """ Call in a loop to create terminal progress bar @params: iteration - Required : current iteration (Int) total - Required : total iterations (Int) prefix - Optional : prefix string (Str) suffix - Optional : suffix string (Str) decimals - Optional : positive number of decimals in percent complete (Int) length - Optional : character length of bar (Int) fill - Optional : bar fill character (Str) """ percent = ("{0:." + str(decimals) + "f}").format(100 * (iteration / float(total))) filledLength = int(length * iteration // total) bar = fill * filledLength + '-' * (length - filledLength) print('\r%s |%s| %s%% %s' % (prefix, bar, percent, suffix), end = '\r') # Print New Line on Complete if iteration == total: print() # # Sample Usage # from time import sleep # A List of Items items = list(range(0, 57)) l = len(items) # Initial call to print 0% progress printProgressBar(0, l, prefix = 'Progress:', suffix = 'Complete', length = 50) for i, item in enumerate(items): # Do stuff... sleep(0.1) # Update Progress Bar printProgressBar(i + 1, l, prefix = 'Progress:', suffix = 'Complete', length = 50) # Sample Output Progress: |█████████████████████████████████████████████-----| 90.0% Complete 使用python以相反的顺序读取文件 Python中的整数缓存有什么用?
