For example: import pandas as pd # version: '0.16.2' or '0.20.3' >>> a = pd.DataFrame({'col1': [np.nan, 1, np.nan, 3, np.nan, 5, np.nan]}) Out[1]: col1 0 NaN 1 1.0 2 NaN 3 3.0 4 NaN 5 5.0 6 NaN >>> a.interpolate(method='linear') Out[2]: col1 0 NaN 1 1.0 2 2.0 3 3.0 4 4.0 5 5.0 6 5.0 >>> a.interpolate(method='nearest') Out[3]: col1 0 NaN 1 1.0 2 1.0 3 3.0 4 3

Initially I thought that 'groups' would be fit for it, but I already realized they're not intended for that (see this question: TestNG BeforeMethod with groups ). Is there any way to configure a @BeforeMethod method to run only before specific @Test s? The only ways I see are workarounds:

I am not asking to modified any MP4 files, just extract metadata such as Width and Height and bitrate and encoding and this is not in the MP3 tags. I have tested Xuggle which works, but I need to have a library that does not use JNI or any native code. I already looked into MP4Parser, and Apache Tika, and they both does not extract metadata, just tag info or alter the file. Is there such java lib? 回答1: I actually found what I was looking for using Mp4Parser here is a simple lines of code to get

So, the problem is that the Decorator1 registers inadvertently, when I register all the ICommandHandler<> 's. How can I filter DecorateWithAll() to decorate all ICommandHandler<> , except Decorator1<> ? 回答1: ObjectFactory is obsolete. You can exclude
