B. Assuming by "distance" you meant "difference" and/or that the
distance is only in 1 dimension:
from operator import itemgetter
firsts = map(itemgetter(0), main_list)
distance = max(firsts) - min(firsts)
I think the above expression is overcomplicated. The code below does the
exact same thing and is easier to understand, IMHO:
firsts = [item[0] for item in main_list]
distance = max(firsts) - min(firsts)
