I have the following data frame for example. What I am trying to do is get the first column to be the index. When I try to do this, it doesn't work. When I am able to set the index successfully, I get a bunch of NaN's. Thank you!
0 1 2
0 842 Bill Smith
1 841 John Fisher
2 843 Barb Macdonald
Assuming your dataframe is variable
# not in-place df = df.set_index(0) # in-place df.set_index(0, inplace=True)
