Solve the following python programming problem given the following code:
# #Using the example used for sketch.
# def export_df(df,name):
#     select_df = df[["Session Id","Selection","Feedback Text","Cleaned method 1","Cleaned method 2","cases","Time_seconds","Timeshifted","Duration"]]
#     writer = pd.ExcelWriter(name+'.xlsx')
#     select_df.to_excel(writer,'Sheet1')
#     writer.save()
#
# export_df(df_gaps,'gaps')
# export_df(df_test,'test')
Given the above code, generate some markdown instructions for it.

#Here is the Python code you requested.

TO DO
Ordered in some kind of general priority (in terms of need of feedback and desired feature)

Fix other Other category
fix visual component of build, delete and submit
clean visual - embellish
run on all 9 student pairs

What can invention be? (Rename as Other)  - Two options:

Lots of differernt pre-set possibilities 
Anytime they use addition within a step?
Anytime they use multiplication
Use a combination of central tendency
Use a combination of methods (range and mean)

Any method that isn't other methods
after removing chuncks that fit our methods, is there anything left?
or
anything that has more than two steps subtracting time coords of methods.


Done

central tendency (average median sum) - add "choose 2 4 5 7" in regex
Show the method that eventually “cracks” the cases (succeeds to solve and move on)

Testing
What works
* Central al works
* Combo of central all works
* COunt gaps (even one gap) works. It doesn't light up when counting case numbers
* Combo of count gaps and Average
* Combo of count gaps and range
What doesn't
* Central choose...
* st1 5 st2 9 - 1 lights up range (good) but not single value
* Combo count al + distance doesn't light up distnace nor Other
