Midterm Exam 2 Review Fall 2004: Count 'em up

Post answers, comments, and questions here!
(Back to Fall2004 Midterm 2 Review)



This is what I think to be the solution for part b:

def countAsBsCs("string"):
count=0
for i in "string":
if i=="1" or i=="2":
count=count+1
print count
Victor Du

If the string as A's and B's in it, why would you look for 1's and 2's? Why are you putting quotes around the variable "string"? Mark Guzdial


def countAs(string):
count = 0
for letter in string:
if letter == "a":
count = count + 1
print count

def CountAsBsCs(string):
  count = 0
  count1 = 0
  count2 = 0
  for letter in string:
    if letter == "a": 
      count = count + 1
    if letter == "b":
      count1 = count1 + 1
    if letter == "c":
      count2 = count2 + 1
  print "as =",  count
  print "bs =",  count1
  print "cs =",  count2

Do see FAQ for how to post code so that we can all read it, please. Mark Guzdial


def count(string):
  print "Number of As = ",string.count('a')
  print "Number of Bs = ",string.count('b')
  print "Number of Cs = ",string.count('c')
