As we've seen, function merge copies each element into its result exactly once, so with these two lists, this merge step takes roughly ... Problem: Say you have a list of lists (nested list) and you want to find the maximum of this list. It’s not trivial to compare lists—what’s the maximum among lists after all? For evaluating less than or greater than, if we know that tuples can contain items of different types, then we need to use map() function to convert all values both tuples into a single type. Found inside – Page 274For example: a = [1,2,3] #create two lists b = [4,5,6] print(a+b) #plus concatenates them c = [] #make a new list #go through old lists for i in range(0 ...
