在这个例子中,check_condition函数作为回调函数传递给main_loop,并在特定条件下终止循环。 2、使用lambda表达式 lambda表达式是一种匿名函数,可以用于简化回调函数的定义和传递。 main_loop(lambda count: count >= 5) 在这个例子中,使用lambda表达式作为回调函数来终止循环。 通过以上几种方法,可以在Python中灵活地控制...

while loop - 无限循环 如果条件从未变为假,则循环成为无限循环。在使用While循环时必须谨慎,因为此条件可能永远不会解析为False值。这导致了一个永无止境的循环。这样的循环称为无限循环。 #!/usr/bin/python var=1 while var == 1 : # This constructs an infinite loop num=raw_input("Enter a number :...
A while loop can be more flexible since the condition can be based on complex logic. A for loop is more structured and readable when dealing with sequences. Both loops can include nested loops, and you can use the continue and break statements to control the flow within them. Understanding ...
for 语句 Python for 循环可以遍历任何可迭代对象,如一个列表或者一个字符串。 for循环的一般格式如下: for <variable> in <sequence>: <statements> else: # else 子句在循环正常完成时执行,这意味着循环没有遇到任何 break 语句。 <statements> 1. ...
