Python: Count most and least common characters in a given string

Python Collections: Exercise-21 with Solution

Write a Python program to count most and least common characters in a given string.

Sample Solution:

Python Code:

from collections import Counter 
def max_least_char(str1):
    temp = Counter(str1) 
    max_char = max(temp, key = temp.get)
    min_char = min(temp, key = temp.get)
    return (max_char, min_char)

str1 ="hello world"
print ("Original string: ")
print(str1)
result = max_least_char(str1)
print("\nMost common character of the said string:",result[0])
print("Least common character of the said string:",result[1])

Sample Output:

Original string: 
hello world

Most common character of the said string: l
Least common character of the said string: h

Python: Tips of the Day

Inverts a dictionary with non-unique hashable values:

Example:

def tips_collect_dictionary(obj):
  inv_obj = {}
  for key, value in obj.items():
    inv_obj.setdefault(value, list()).append(key)
  return inv_obj
ages = {
  "Owen": 25,
  "Jhon": 25,
  "Pepe": 15,
}
print(tips_collect_dictionary(ages))

Output:

{25: ['Owen', 'Jhon'], 15: ['Pepe']}
