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
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
