For example, replace the 2nd element with 11 in each sublist if it’s greater than 5. If a=[[1,2],[4,5],[7,8],[3,6]] then the desired results would be  a=[[1,2],[4,5],[7,11],[3,11]]. if possible via list comprehension

Why not extend Mats' example?

for sub in a:
     if sub[1] > 5:
         sub[1] = 11

Why the list comprehension, what do you gain, if anything, from using one?
