I have my data in this format :
| Harvard | MIT |
|---|---|
| David | Troy |
| Siri | Charlie |
| Troy | David |
| Alexa | Cortana |
| Cortana | Man |
| Animal | David |
and I want my results to be in :
| Harvard | MIT | Output |
|---|---|---|
| David | Troy | David |
| Harvard | MIT | Troy |
| David | Troy | Cortana |
| Siri | Charlie | |
| Troy | David | |
| Alexa | Cortana | |
| Cortana | Man |
I don't care the order I get the name, just I need the list of person who are attending both institutions. I have them stored in same csv file but different column.
Python is my preferred language. Or I have git bash Installed on my windows either. I need a solution.
CodePudding user response：
The following line of code should solve your problem.
df['Output'] = df['Harvard'].loc[df['Harvard'].isin(df.MIT.values.tolist())]
You can sort the Output-column afterwards, if you want to.
