efficient word indexing in python

Apologies for the basic question, how can I find the indexes ((1,2),(2,1),(2,2)) corresponding to “yellow” in ref and store them so that I can access them afterwords without rerunning the search?

ref1 = "this is a test" 
ref2 = "this is a yellow test"
ref3 = "this is yellow"
ref4 = "yellow and orange are colors"
ref = ((ref1,ref2),(ref3,ref4))

Answer 1

Just for the sake of it:

[(k,i) for k,m in enumerate(ref, 1) for i,j in enumerate(m, 1) if 'yellow' in j]

but you probably want the real index (starting at zero)… Remove the second argument of enumerate if so.
