I have 5 datasets, as CSV files, they each contain event logs on a computer, Monday-Friday.

So:

```
Monday.csv
Tuesday.csv
Wednesday.csv
Thursday.csv
Friday.csv

```

I was wondering how I could merge all of these together into one big file, each dataset, is identical in format with 80 columns as well as track of which day of the week it was, when looking at this larger dataset with all 5 days.

So all 5 csv's would become 1 bigger one like:

```
Week1.csv

```

Could this be possible with pandas? or would I need another library?

**Update**
[Import multiple csv files into pandas and concatenate into one DataFrame](https://stackoverflow.com/questions/20906474/import-multiple-csv-files-into-pandas-and-concatenate-into-one-dataframe) This helps me do it.

**But** my CSV files include the first row as a header, when I merge them it includes the same header 5 times through the document when the pdf's merge, is there a way to remove the first column from each one before you merge them?
