try:
pandas.set_option('display.max_columns', None)
but depending how many columns you have this is not a good idea. The data is being abbreviated because you have too many columns to fit practically on the screen.
You might be better off saving to a .csv to inspect the data.
df.to_csv('myfile.csv')
or if you have lots of rows:
df.head(1000).to_csv('myfile.csv')
