Write in a csv file - jeuvrey - Mar-07-2019 Hello, I receive a data stream i want to record in a variable (array, list or dictionnary) and then write these data in a csv file. My streamed data are coordinates of multiple marker. Hence at each loop i receive a data frame (marker1:x,y,z; marker 2:x,y,y ect..), so for exemple with 4 markers i receive 12 streamed data at each loop. I would like to write these data in a csv file like this (data separated with tabulation): marker 1.... marker 2....marker3 ect... x y z......x y z......x y z 1 2 3......5 5 6......4 9 8 4 5 6......7 2 4......4 6 5 It seems simple but i really don't know what/how i can use array, list or dictionnary to do that. Any help please? Thanks RE: Write in a csv file - Larz60+ - Mar-07-2019 you can do it directly in pandas, see: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.to_csv.html |
