Answer 1

Pandas' read_csv function has a skiprows argument, which will let pandas know to skip either a fixed number of lines or a list of line numbers. In this case, you can use:

df = pd.read_csv('data.csv', skiprows=2)

Please see use in the documentation .

PS: This assumes the actual data is comma-separated. Otherwise, you can define a custom delimiter with sep argument.

Answer 2

Pandas is likely having a hard time parsing your CSV because of the filename and time data at the top of your file. If you delete those, and then use read_csv() in pandas again, it should not have any issues reading a tab or space delimited file.

EDIT: @Avidiotic's response is a better solution if you don't want to manually delete the lines, or you want to persist the filename and time data.
