For loop inside a Jupyter notebook

So I'm trying to run this process in a Jupyter notebook for a variety of accounts, then save the output file depending on the handle I am going for. Basically I would like to automate this process rather than me changing the querysearch parameters in my command line every time.

```
import got
retailers = ["handle1", "handle2"]

for retailer in retailers:
string = "keyword " + "@"+ retailer
file_name = "keyword_" + retailer
%run Exporter.py --querysearch retailer --since 2018-01-01 --maxtweets 50 --output file_name
````

However I have the problem where GOT is searching for the term "retailer" and not actually what I want, which is "keyword @retailer". Same for the output file, which is being saved as "file_name" and not "keyword_retailer".

Any ideas on how I can solve this?
