over it, not when you create it. For example, >[i*i for i in range(5)] produces a list, [0, 1, 4, 9, 16], while >(i*i for i in range(5)) produces a generator object that will produce those numbers when you iterate over it. ...
它的参数类型是int, list of int, None, 或者是默认的'infer' 它的功能是:Row numbers to use as the column names, and the start of the data. 也就是,它是把某一行作为列名,并且,这一行是数据开始的行。我们测试一下。刚才我们在a.csv文件中只写了两行数据,为了方便测试,我们写上5行数据(大部分...
