By default, when printing out a large number of columns, they will be truncated like so:
Index(['AAAAAA0', 'AAAAAA1', 'AAAAAA2', 'AAAAAA3', 'AAAAAA4', 'AAAAAA5','AAAAAA6', 'AAAAAA7', 'AAAAAA8', 'AAAAAA9',...'AAAAAA990', 'AAAAAA991', 'AAAAAA992', 'AAAAAA993', 'AAAAAA994','AAAAAA995', 'AAAAAA996', 'AAAAAA997', 'AAAAAA998', 'AAAAAA999'],dtype='object', length=1000)
array(['AAAAAA0', 'AAAAAA1', 'AAAAAA2', 'AAAAAA3', 'AAAAAA4', 'AAAAAA5','AAAAAA6', 'AAAAAA7', 'AAAAAA8', 'AAAAAA9', 'AAAAAA10', 'AAAAAA11',...'AAAAAA995', 'AAAAAA996', 'AAAAAA997', 'AAAAAA998', 'AAAAAA999'],
