Character count in Python

The task is given: need to get a word from user, then total characters in the word must be counted and displayed in sorted order (count must be descending and characters must be ascending - i.e., if the user gives as "management" then the output should be

**a 2
e 2
m 2
n 2
g 1
t 1**

this is the code i written for the task:

string=input().strip()
set1=set(string)
lis=[]
for i in set1:
 lis.append(i)
lis.sort()
while len(lis)>0:
 maxi=0
 for i in lis:
  if string.count(i)>maxi:
   maxi=string.count(i)
 for j in lis:
  if string.count(j)==maxi:
   print(j,maxi)
   lis.remove(j)

this code gives me following output for string "management"

a 2
m 2
e 2
n 2
g 1
t 1

m & e are not sorted. What is wrong with my code?

Solution

  • The problem with your code is the assignment of the variable maxi and the two for loops. "e" wont come second because you are assigning maxi as "2" and string.count(i) will be less than maxi.

     for i in lis:
  if string.count(i)>maxi:
   maxi=string.count(i)

 for j in lis:
  if string.count(j)==maxi:
   print(j,maxi)

    There are several ways of achieving what you are looking for. You can try the solutions as others have explained.
