Quote only the required columns using pandas to_csv

问题

I need to generate a csv using pandas to_csv function. I tried quote=csv.QUOTE_NONNUMERIC. But for one of the date time column I dont need double quotes.

Is there a way to select the columns for which we want double quotes?

回答1:

Thanks people. I got the answer so just thought to share.

First I got the list of headers to be quoted and looped them something like below:

for col in quoteColumnsList:
    df[col] = '"' + df[col] + '"'

Here my quotechar is '"'. Now I used to_csv with quote parameter as csv.QUOTE_NONE. This way we get the double quotes only to the required columns.
