In the above code, we were dealing with a string containing an even number of characters. Thelen()function here is used to return the length of the string. We split the string into one half containing the first half of the characters and the second substring containing the other half. ...

defaultdict的default_factory仅在为__getitem__调用提供默认值时才会被调用,而不会为其他方法调用。例如,如果dd是一个defaultdict,k是一个缺失的键,dd[k]将调用default_factory来创建一个默认值,但dd.get(k)仍然返回None,k in dd为False。 使defaultdict工作的机制是调用default_factory的__missing__特殊方法,这...

for x in array: if x < pivot: less.append(x) else: greater.append(x) 冒号标志着缩进代码块的开始,冒号之后的所有代码的缩进量必须相同,直到代码块结束。不管是否喜欢这种形式,使用空白符是Python程序员开发的一部分,在我看来,这可以让python的代码可读性大大优于其它语言。虽然期初看起来很奇怪,经过一...
