I have a column in a data frame that has values of either 1 or 0. I'm attempting to get the portion of the data frame after the first 1 to 0 transition because I need to count the number of 0 to 1 transitions after that point

I tried df.loc[df["column name"] == 0] but the resulting dataframe only contains 0

I'm there's a simple method but I'm new to pandas.

Do you know that the column starts with a 1? That is, do you have to look for the first 1 to 0 *transition* or can you just look for the first zero? – BrenBarn Jan 20 '16 at 19:10
I actually just need to look for the first 0 – Mikes1962 Jan 20 '16 at 19:17
