I just wanted to thank you for such a great explanation of joins. I did not have it explained to me and struggled for the longest time to understand them. It takes a good teacher and someone who can understand it simply for one to understand it. Seriously, you are amazing!!

The best new feature with merge is the validate option to make sure your join is 1:1, 1:M, etc. This is very useful for machine learning projects or end user reports that rely on upstream data that is updated regularly. It's saved me headaches a few times.

The "validate" option is great, I agree! I also like "indicator", which I explained here: twitter.com/justmarkham/status/1153653794829418496

I have 5 csv files that come out daily each containing a date column. i want to merge them all using the date as the merge field. i tried a basic merge with 2 of the csv files and date was used as the merge-on field by default - so it worked. ultimately i just need one date column in my masterfile with all the other column data merged. should I continue to do this or is it better to set the date column as the index, or something else?

You're great teacher! I see the despite having a large 100K row file, the number of rows do not get expanded after the merge. They beautifully stay the same and just add the movie titles to the reviews. Can you comment on why this is not always the case. I have tried and my output file gets expanded by a few rows (17 out of 1000) and I have not been able to figure out why. I have checked multiple videos and some come absurd not practical solutions (like the files are the same size) or arbitrarily eliminate any dups (despite some may be valid rows), but none explain the reason and how to identify those rows that could be dups. Your comments are appreciated.

You are a great instructor. I have learned a lot from you regarding pandas. The video with title "How do I merge DataFrames in pandas?" has left some queries in my mind. I would be thankful to you if you clear those too. What type of join is used here movie_ratings = pd.merge(movies , ratings)? if it is inner join it should result in 1682 rows in total in movie_ratings dataframe, as movies dataframe has 1682 rows. But in video i have observed that movie_ratings results in 100,000 rows of data.

Great video. However I have a little issue. I have 3 data frames that I am trying to merge together. The first is a pretty long database with columns (cust_id, gained_on gained_from_supplier, lost_to_supplier, sales_channel_id) the second is the supplier data frame (supplier_name, supplier_id) what I am trying to do is merge the supplier id and name from the second data frame, to the database frame which has the ID so supplier id to the number using the lefton/right on but instead it returns both columns - the supplier ID and name of both dataframes. Then the same with the channel data frame (sales_channel_name, sales_channel_id) and merge this with the sales_channel_id in the database dataframe and show the name instead. Any help would be appreciated, thank you!

Is there a way to highlight difference between columns in this merged database. example: Number of Vehicles_SS: 7 vs Number of Vehicles_SA: 2 and it would highlight the row, or even just those those values, base on the ID it was merged on? I am having a hard time find this. Trying to get rid of VBA, which i have doing this, But it is SUPER slow with the data I have to process.

How do I merge df1 and df2 by two columns (fiels) at clausula on? For example: dfUltStatus = pd.merge(dfUltStatus, dfDescStatus, on=['CODIGO_STATUS','SUB_CODIGO_STATUS'], how = 'left') The object is merge the two data frames through these two fields to bring the description field.

Love your videos!! excellent tutorial - by chance does Pandas have a facility to do a semi_join() like Dplyrs function?
