Looking for data/info on a perticular data-proccesing problem.

This is one way to get these results:

1. convert the lists to sets,
   
2. take the union of all three sets
   
3. convert union to set
   
4. then convert that set to a list
   
5. sort the list
   

Example:

taba = ['aligators','bats','eagles']
tabb = ['bats','cats','eagles']
tabc = ['cats','dogs','eagles']

tlist = list(set(set(taba).union((set(tabb).union(set(tabc))))))
tlist.sort()
print(f"tlist: {tlist}")

Output:
tlist: ['aligators', 'bats', 'cats', 'dogs', 'eagles']
