Delete the first three rows of a dataframe in pandas

Question

I need to delete the first three rows of a dataframe in pandas.

I know df.ix[:-1] would remove the last row, but I can\'t figure out how to remove first

Answer 1

I think a more explicit way of doing this is to use drop.

The syntax is:

df.drop(label)

And as pointed out by @tim and @ChaimG, this can be done in-place:

df.drop(label, inplace=True)

One way of implementing this could be:

df.drop(df.index[:3], inplace=True)

And another "in place" use:

df.drop(df.head(3).index, inplace=True)
