Data analysis in Python with pandas
[ad_1]
Wes McKinney
The tutorial will give a hands-on introduction to manipulating and analyzing large and small structured data sets in Python using the pandas library. While the focus will be on learning the nuts and bolts of the library’s features, I als

how can i apply complex 2nd order differential equation to python dataframe to create column bsed on it
hands-on
51:30 Series
57:50 Dataframe
watching in 2020 and still the best for intermediate level, awesome
This is Wes McKinney the man who invented Pandas.
Great talk at that time in 2012, in parts outdated now in 2019 but nevertheless interesting to watch history.
The time take by lambda is faster than apply… at 2:19:50
Transform did 10 loops at 46ms which is 460 ms
Apply did 100 loops at 15ms which is 1500ms
No, BOOOO!! It is faster…
3:02:32 why not just use pd.to_frame() to convert series into df?

Thanks for such great video. Kindly share the zip file you have used for the lecture.
Even this was 5 years ago, I would not pay to go to Pycon when you have instructors that are NOT prepared for there tutorial / lecture. Also is paying all that money to see lame slides and no coding being done.
http://ow.ly/9w920 This link isn't working now.how can I get the files
Good day all, i am a post graduate student working on "Detecting and preventing SQL injection attack on a database using machine learning approach". My Major challenge right now is generating the dataset and how to write the appropriate code in Python, i will be highly grateful if any one can help me out in generating the python code to do that, thanks alot.
at 2:14:05 I have it as written in the tutorial:
boys['year_rank'] = grouped.transform(pd.Series.rank)
but this triggers a warning to use the .loc method with a link to this documentation http://pandas.pydata.org/pandas-docs/stable/indexing.html#indexing-view-versus-copy I generally understand the idea, that it is creating it from a copy which may not be accurate in memory.. but.. how do I add the rank column to the dataframe using the .loc method? thanks
I nearly run out of patience, you only see the codes at 47:59!
how to enable or activate the methods to popup based on the python objects i use in the IPython notebook. Whenever i use python objects and access enter ., no methods list or autocompletes.
If you know the theory and want go straight to the fun : @ 47:57
Applying functions to axis labels for GroupBy just melted my brain
20:17 for the actual presentation
Simply, it's a good tutorial for beginners !
Be patient, and watch all the video by doing what Wes does ..
