row = 1 # 行数，从1开始while row <= 9: # 当行数小于或等于9时继续循环 col = 1 # 每行开始时，列数重置为1 while col <= row: # 当前列数小于或等于行数时继续循环 print(f"{col} x {row} = {col * row}\t", end="") col += 1 # 列数递增 print() # 每完成一行后换行 row ...
names = [] new_name = '' while new_name != 'end': new_name = input("Type the names to be added and end with 'end': ") names.append(new_name) print(names)运行上述代码，它将指示用户输入姓名，并通过输入 end 结束运行。输出可能如下所示：[‘Aaron Kennedy’，‘Camile St. Joan...
While...else 与其它语言 else 一般只与 if 搭配不同,在 python 中还有个 while...else 语句 while 后面的else 作用是指,当while 循环正常执行完,中间没有被break 中止的话,就会执行else后面的语句 举个例子 count = 0 while count <= 5: count += 1 print('loop',count) else: print('循环正常执行...
We can use abreak statementinside awhileloop to terminate the loop immediately without checking the test condition. For example, whileTrue: user_input =input('Enter your name: ')# terminate the loop when user enters endifuser_input =='end':print(f'The loop is ended')breakprint(f'Hi{user...

while (x < 5): print(x) x += 1 Flowchart: The following while loop is an infinite loop, using True as the condition: x = 10; while (True): print(x) x += 1 Flowchart: Python: while and else statement There is a structural similarity between while and else statement. Both have ...
