So I have a Series with stock tickers as the index and their industry as the value in the column. The industries are often repeated and what I have been trying to do is return a dataframe or series where the industries are repeated/duplicated.
2000-01-27
AMAT Semiconductors
AMD Semiconductors
ANDW-200712 Telecommunications
CMVT-201302 Telecommunications
CSCO Telecommunications
DTE Electric
So for this example I want to return 3 seperate series/dataframes(because of the 3 unique industries), and one for example will contain AMAT and AMD because they are both semiconductors etc etc. However I cannot think of a way around this. I have tried using .duplicated() nd other various built in pandas functions but cannot think of a solution so if anyone can help it would be much appreciated.
