So, I just take all the letters in our string and use the collections module to list the number of occurrences. Code on repl. EDIT: I approached this with the goal of finding out how many characters are repeated an odd number of times in the string.
Basic idea is to iterate over lowercase characters in a string using a for loop. Instances of each letter are counted using a dictionary. All punctuation and whitespace is iterated over and ignored. Once the characters are counted a second for loop is used to iterate over the dictionary values, each odd number is counted. The function returns False if there are two or more characters occurring an odd number of times in the string. Check out the extra information mainly the How To Participate part for this and other stuff you may want to know.
The premise of this code is to check each character in the testString against a whitelist, permittableChars. Any characters that get passed will be checked against foundChars, a list of characters found earlier in the loop. If no match is found, the character is added to the array. If a matching character is found, its match is removed from foundChars. If foundChars. PS: was it recently added to the extra information page that it is preferred NOT to use the repl.
It is expected that if an input string is a palindrome, the loop will end with an empty set all letters in even numbers or a set containing a single letter a pivot letter in palindrome. To account for capitalization, the function first transforms the input string into lowercase.
