foo=long_function_name(var_one,var_two,var_three,var_four) 当if语句的条件部分足够长,需要跨多行编写时,值得注意的是,两个字符的关键字(即 if),加上一个空格,再加上一个开括号,会为多行条件的后续行创建一个自然的4个空格缩进。这可能会在if语句内嵌的缩进代码块的可视上产生冲突,后者也会自然地缩进...

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,经过一段...

I realize that getting an issue without exact steps to reproduce is unhelpful. However, I am more than willing to try out test builds or build a customer version to gather more details if I can get some guidance. I was able to easily build a custom version on Linux per the dev docs,...
2. 不要贪多,选一个知名度高的Python教程,教学为辅,练习为主。每天用15分钟学习课程,剩余时间就用来做编程练习好了。要随时记住,我们学习Python的目的在于会用,而不是背过了多少知识点。 嘻嘻,这里给大家推荐一个我挺喜欢的python课程——夜曲编程。我刷了一些编程题目,竟回想起,当年备考雅思时被百词斩支配的恐...
To be consistent with surrounding code that also breaks it (maybe for historic reasons) -- although this is also an opportunity to clean up someone else's mess (in true XP style). Because the code in question predates the introduction of the guideline and there is no other reason to be...
