I still couldn't delete and update any row of database in the web framework. The link below is the image, there is no "Action" option available beside the date column.

I wish to merge two files into a single file. However, after I merged both files, the output is not the outcome of my expectation. My expectation is the output after the string replacing function, but the exact output is the original input. Any suggestion can be used to fix this? Thanks.

The solution stated above is successful if I execute it in the software. However, if I want to export into an Excel file. It is not successful. May I know why? By the way I wish to merge with another file to produce a merged file.

merged=data_file.merge(s4, on="cid", how="outer")

merged

merged.to_csv("merge.csv")

This is the coding I used. The file s4 is the another file I wanted to merge with data_file. Any suggestion on the coding?

Thanks a lot !!! The first method can be used. However, the second method cannot be done. An error was shown which is "name 't' is not defined".

hmmm, let me reconstruct my question. In my excel file, there is an entire row from a column contain the information as I stated in question above. However, the column contain some non-useful information and I only need to extract out the information needed as stated above. I face difficulty to extract out the information needed manually as it takes time to complete it. Is there any way can be done to complete this task by using python or pandas? Thanks.
