Merging Multiple DataFrames | Merging More Than Two DataFrames | Conditional Merge | Merge with Where Condition | Sub Query
This video is an advance level video about merging the dataframes, which doesn't just tells you how to merge multiple tables but also explains how you can do the conditional Merge useing .Query function just like we do sub queries in SQL.

What if we have couple of more dataframes that needs to be merge. Using .merge() every time would be tedious. Isn't there any other way to solve that issue

you can try these - Concatenation: If you have data frames with the same columns but different rows, you can use the pd.concat() function to concatenate them vertically. This function concatenates data frames along a particular axis and can be used to combine multiple data frames into a single data frame. Joining: If you have data frames with different columns but the same index or column names, you can use the df.join() function to join them horizontally. This function merges data frames based on their index or column names and can be used to combine data frames that share common keys. Appending: If you have data frames with the same columns and want to add more rows, you can use the df.append() function to append new rows to an existing data frame. This function appends rows to the end of the data frame and can be used to combine data frames that have the same structure. Merge with loop: If you have a list of data frames that you want to merge, you can use a loop to iterate through the list and merge each data frame with the previous one. This can be a more efficient way to merge multiple data frames than using .merge() every time.

@@learnerea I never thought of merging with a loop - that’s way better than .merge() forever
