Hey everyone. Hope you're all having a great weekend. I'm still working on finishing up the series. Let me know if there is anything specific you want me to cover. In the next video I'll be covering sorting, and some videos still to come include: working with dates, aggregating data, reading and writing to/from different sources, and a discussion on the recent Pandas version 1.0 release. Let me know if there is anything else you'd like to see! Thanks and have a good one!

Probably there is only an inplace-parameter if only the affected data (or not much more) gets changed. Append for example probably uses the numpy append which is not inplace, so all the data must be copied. For drop no time-consuming changes need to be done, just one key and pointer get removed

Hey @coreyms thanks for the video, i seem to have issue with the code when appending, It may be due to updates, just wondering if there is a workaround for that. The problem I have faced is ''DataFrame' object has no attribute 'append'', i believe that append is replaced by concat() but note entirely sure of execution of it in terms of blending both dictionaries this is what worked for me df1 = pd.concat([df1, df2], ignore_index=True) thanks

Hi i hope you are doing well @corey schafer I have a question as in this video you explain how to add and remove a row and also how to drop a column and how to combine two columns and how to split a column into two or multi columns but you didn't explain if i want to add a single columns So i search on internet for that and found some ans like 1. Df['age']=['value you want to assign'] 2. Insert Df.insert(5,"age",[list of value you want to assign ] 3. Assign Df.assign(name with ' '=[list you want to assign] They have a problem you have to assign exit amount of value your data frame have if you miss a single value its gives a error Also assign doesnt work at orginal data frame when i try inplace =True its creat a new column with name inplace and all value were True So why assign is not working and how can i lift a value empty or create a column without any value like nan

I know I'm late to the party, but I found out why .apply doesnt work with inplace=True. inplace = True only works for functions that apply specific, localised changes to fill or change those specific ones ( such as .replace(), .fillna() ) It also works for arranging data functions, (in this video, .rename() ) X = However, transformative functions that apply a change to the entire dataframe does not work (such as .apply() , .transform() ) as they would create an entirely new data set when used. To make the changes, just gotta do the df = df.function

I am a bit confused as to how the drop method knows which rows to remove when we are using a filter. We create a filter and apply it to our df and it returns some boolean values. When we type df.drop(index=df[filt].index) we are basically saying drop the values with the index of our filter? It is working, it removed the rows I wanted but I can't figure out how it's working. When I printed filt.index it returned a rangeIndex with 6 values (I had 6 rows), some are false and some are true. But when I print df[filt].index it returns the rows 0 and 1 which is the rows that have the value True. So does .index work different depending on where you apply it? In the case of df[filt].index it will return the index where the value is True?
