[Python] 2-d for loop iterates one letter at a time

I've been working on a code which will flip the order of elements backwards using 2 functions, for some reason the first function which can normally print out two or more lists with spaces between each element is putting a space between each letter of the flipped list, could you tell me why it's doing so

cities = [["Miami", "Atlanta", "Dallas", "Los Angeles"], ["New York", "Chicago", "Portland", "Sacramento"]]

def printList(nightwatch):
for r in nightwatch:
for c in r:
print(c, end=' ')
def flipOrder(listy):
temp = []
for r in range (len(listy)):
for c in range (len(listy[r])):
temp.insert (0, listy[r][c])
listy = temp
printList(listy)

printList(cities)
print ()
print ()
print ()
flipOrder(cities)


I've tried implementing the first function into the second as well as messing with the c and r loop, however this usually just causes the code to stop working, ideally i'd like to know why this is processing the list one letter at a time
