pdb.set_trace() return a / b result = divide(10, 2) 这种方法适用于需要深入分析代码执行过程和解决复杂问题的场景。 十五、使用自定义输出函数 通过创建自定义输出函数,可以实现灵活的输出控制。例如,可以创建一个通用的display函数,根据需要输出不同类型的结果。这样可以提高代码的可复用性和维护性。 def dis...

Milliseconds countdown timer in python, You sleep about 1 s - this may pan out to exactly 1000ms or be slightly more (never less) - why do you need ms displaY? Indentation is part of Countdown Clock: 01:05 Solution 1: In addition to converting your time to minutes and seconds, it ...

您想在父对象上设置display: flex;。在这个例子中,我称之为.wrapper。因为.ratio-background没有内容,所以需要定义一个width来显示它。 .ratio-background { background-color: red; width: 90%;}.ratio-main { height: 12px; background-color: green;}.wrapper { display: flex; align-items: center; ...
a: 13 可见全局变量a发生了改变。 Python支持嵌套函数(闭包),但python 2只支持在最里层的作用域和全局命名空间中给变量重新赋值,内部函数是不可以对外部函数中的局部变量重新赋值的,比如: 1 2 3 4 5 6 7 8 9 10 def countdown(start): n = start def display(): print n def decrement(): n -= ...
