Pandas Read csv 只读取一行

Question

I have a classic panda data frame made of ID and Text. I would like to get just one column and therefore i use the typical df["columnname"] . But at this point it becomes a Pandas Series. Is there a way to make a new dataframe with just that single column? I'm asking this is because if I cast the Pandas series in a string ( columnname = columnname.astype ("string") ) and I save it in a text file, I see that it only saves the first sentence of each line and not the entire textual content, as I would like.

If there are any other solution, I'm open to learn :)

Answer 1

试试这个： pd.DataFrame(dfname["columnname"])
