list 的 sort 方法返回的是对已经存在的列表进行操作,而内建函数 sorted 方法返回的是一个新的 list,而不是在原来的基础上进行的操作。 sum() 求和 >>> sum([1,2,3]) 6 >>> sum([1,2,3],4) 10 1. 2. 3. 4. print() 输出函数 >>>print('人生苦短,我用python') 人生苦短,我用python >...
1或’columns’:减少列,返回一个索引为原始索引的Series。None:减少所有轴,返回一个标量。skipna: bool, 默认 True,排除NA/null值。如果整个row/column为NA,并且skipna为True,那么对于空row/column,结果将为True。如果skipna是False,那么NA就被当作True,因为它们不等于零。 pd.Series([True, True]).all() pd...

return [value for key, value in items] 又一个按照key值排序,貌似比上一个速度要快点 def sortedDictValues2(adict): keys = adict.keys() keys.sort() return [dict[key] for key in keys] 还是按key值排序,据说更快。。。而且当key为tuple的时候照样适用 ...

最后,训练数据的去重和shuffle,也完全可以不用python去写,分别用uniq和shuf结合管道就能一行命令搞定: sort train.tsv.cut | uniq | shuf > train.tsv 总之,类似于cut,wc(统计词数、行数的神器)的这种linux中的小命令很多,很大程度上帮我们解决了一些简单高频的数据集处理的需求(尤其CSV),避免了无脑使用python导...
