What I need it to look like: https://imgur.com/a/L2uhoXY

I imported the file as a tsv and converted it into a csv. After doing so, this is how I imported my data train = pd.read_csv('./gene_train.csv', sep ='\\t') train.shape

Answer 1

You did not show how your dataframe looks like. But in general, you can get a list of all column names of a dataframe by

colnames = list(train.columns)

and now you said it is shifted by +1 to the right. I assume it means data of column 1 should match colnames[2] . So you can re-assign the column name by:

train.columns = colnames[1:]

but, in this way, you will miss the "rightmost" or last column and you have to fix that.
