python中判断一个dataframe非空 DataFrame有一个属性为empty,直接用DataFrame.empty判断就行。 如果df为空,则 df.empty 返回 True,反之 返回False。 注意empty后面不要加()。 学习tips:查好你自己所用的Pandas对应的版本,在官网上下载Pandas 使用的pdf手册,直接搜索“empty”,就可找到有... ...

Now saying it's not adding overhead is not completely true, however it's a minimal overhead (creating lock, entering context manager, ...). And what about the other occurrences ofimport_modulein Django code? I think that at some point we have to trust Python for not regressing in that...
Python, whilst being a popular tag, has very few relationships, only being weakly linked to PHP. When I published this visualisation on my blog the feedback was very positive. So I decided to tidy up my code and create a generic Silverlight control that can graph relationships between a set...
