python clear csv file

Question

how can I clear a complete csv file with python. Most forum entries that cover the issue of deleting row/columns basically say, write the stuff you want to keep into a new file. I need to completely clear a file - how can I do that?

Answer 1

Basically you want to truncate the file, this can be any file. In this case it's a csv file so:

filename = "filewithcontents.csv"
# opening the file with w+ mode truncates the file
f = open(filename, "w+")
f.close()
