Export Pandas to CSV without Index & Header - Spark By {Examples}
December 10, 2024 - In order to export Pandas DataFrame to CSV without an index (no row indices) use param index=False and to ignore/remove header use header=False param on
Pandas Index Column - is Drop() possible?
As far as I understand your question (I am not sure). Data Frame is a pandas object to do various tasks on tabular data it is not a file. pd.read_csv("filename.csv",index_col=False) means to read data from a CSV file to pandas Data Frame object. Parameter index_col is the index position of the column index to be used as the index of your data i.e 0 - your first column will be set as the index, 1 - your second column of the data will be used as the index etc. False is interpreted by Python as a 0 column going to your index. To perform your task I suggest creating two Data Frames. pd.read_csv and pd.read_excel work around with two Data Frames merge them and then by pd.to_excel save your merged Data Frame as an XLSX file. while saving your file you can set Header=False or Index=False to not have your column or row index appear in your XLSX file.

Honestly, I’m not sure what a lot of this is doing, but this seems odd to me: TEAM_COMB = df.columns Are you sending a dataframe or just columns to CSV? Just a guess…I’m sure someone with a bit more pandas experience will come along :) More on reddit.com

July 9, 2023Exporting pandas.to_csv() doesn’t export all rows
If you're looking at that CSV in Excel, note that some versions of Excel itself limits how many rows it can display. If I recall correctly, some versions can only display ~65K rows, which sounds similar to your issue. pandas.to_csv() definitely exports the whole dataframe, so the problem is almost certainly with how you are trying to view the data. Load the CSV back into Pandas and I suspect you'll see all the rows are there. More on reddit.com

There are two ways to handle the situation where we do not want the index to be stored in csv file.
As others have stated you can use index=False while saving your
dataframe to csv file.df.to_csv('file_name.csv',index=False)- Or you can save your dataframe as it is with an index, and while reading you just drop the column unnamed 0 containing your previous index.Simple!
df.to_csv(' file_name.csv ')
df_new = pd.read_csv('file_name.csv').drop(['unnamed 0'],axis=1)
