Maximum Occurrence Letter - GalaxyCR - Nov-27-2017

Hey Guys, So I have an assignment regarding finding the most letters used in a word. For some reason I can't seem to make it work as the output that I get is based on First Letter. The def function for max_char_count I got from stack overflow if I'm not mistaken. Any help will be appreciated.

This is my Code.

global str1
def main():
    str1 = input("Enter Your Message: ")
    
    print ("The Lenght of Your Message is:", len(str1),)

    print (max_char_count(str1))

    
def max_char_count(str1):
    max_char = ''
    max_count = 0
    for char in (str1):
        count = str1.count(char)
        if count > max_count:
            max_count = count
            max_char = char
        return max_char


main()

This is my output.

Output:Enter Your Message: dsdss
The Lenght of Your Message is: 5
d
>>> ================================ RESTART ================================
>>> 
Enter Your Message: saaa
The Lenght of Your Message is: 4
s

Original Def function. I just add the .upper()

def max_char_count(string):
    max_char = ''
    max_count = 0
    for char in set(string):
        count = string.count(char)
        if count > max_count:
            max_count = count
            max_char = char
    return max_char

print(max_char_count('eeFAGAAJeEff'.upper()))

The Output:

Output:>>> 
E
>>>

Nah Nevermind Got it. The return is a space ahead. I don't know how to delete this thread.

In your first function return max_char has the wrong indention. It's one level too deep. It returns inside the loop and you get only the count of the first letter.

To count something, you should look for collections.Counter.

import collections
text = 'This is a test. Hello World. Foo Bar Baz...'
c = collections.Counter(text)
print('Most common')
print(c.most_common(3))

Using collections is probably cheating, but using a dict might be fine:

>>> def max_char(string):
...     chars = {string.count(ch): ch for ch in string}
...     most_used = max(chars.keys())
...     return chars[most_used]
...
>>> max_char("foo bar")
'o'
>>> max_char("spam eggs")
's'
>>> max_char("on a bright sunny day in august")
' '

The important part, is that you actually understand how it works, whichever one you turn in.
