Python 进阶指南(编程轻松进阶):十三、性能测量和大 O 算法分析 对于大多数小程序来说,性能并不那么重要。我们可能会花一个小时编写一个脚本来自动执行一个只需要几秒钟就能运行的任务。即使需要更长的时间,当我们端着一杯咖啡回到办公桌时,这个项目也可能已经完成了。 有时候花时间学习如何更快地制作脚本是明智...
airline_route_lengths["name"] = airline_route_lengths.apply(lookup_name, axis=1) # Remove duplicate values in the index. airline_route_lengths.index = range(airline_route_lengths.shape[0]) 上面的代码会获取airline_route_lengths中每列的名字,然后添加到name列上,这里存贮着每个航空公司的名字。我们...

In Python, a variable points to data stored in a memory location. This memory location can store different values such as integers, real numbers, Booleans, strings, or more complex data such as lists or dictionaries. In the following code, we define a variable port that stores an integer ...
