循环使用 else 语句 在python 中,while … else 在循环条件为 false 时执行 else 语句块: 实例 #!/usr/bin/pythoncount=0whilecount<5:printcount,"is less than 5"count=count+1else:printcount,"is not less than 5" 以上实例输出结果为: 0isless than51isless than52isless than53isless than54isle...
example = ‘asdkfkebansmvajandnrnndklqjjsustjwnwn’ 并且被要求用while和for循环查找这个字符串中的a数 因此,不允许像这样简单地使用count()函数: print('# of a:’, example.count(‘a’)) 我们得到了一个例子:(并被告知找到一种不同的方法) ...
a given sequence, such as a list, a dictionary, a tuple, etc., or we can use it to execute a piece of code repeatedly. If you are new to python, then this article will be great for you in order to understand the difference between the two loops in python –for vs while loop. ...
You'll learn more about the difference between while and for loops in a bit, but for now, concentrate on the following pieces that you need in order to create a for loop: The for keyword A variable The in keyword The range() function, which is an built-in function in the Python libr...

else:可以在循环后使用,如果循环因为条件变为假而退出,则执行else块中的代码。 示例:else 语句 python for i in range(5): print(i) else: print("Loop finished") 在Python中,循环是编程的基础部分,通过合理使用for和while循环,可以实现复杂的逻辑和数据处理。
python while condition: # 循环体 示例 python # 简单的 while 循环 count = 0 while count < 5: print(count) count += 1 # 无限循环(需谨慎使用) while True: print("This is an infinite loop. Press Ctrl+C to exit.") # 通常需要某种退出条件或 break 语句 ...
