Python Challenges: Check if a given string is an anagram of another given string

Python Challenges - 1: Exercise-26 with Solution

Write a Python program to check if a given string is an anagram of another given string.

According to Wikipedia an anagram is direct word switch or word play, the result of rearranging the letters of a word or phrase to produce a new word or phrase, using all the original letters exactly once; for example, the word anagram can be rearranged into nag-a-ram.

Explanation:

Python: Check if a given string is an anagram of another given string

Sample Solution:-

Python Code:

def is_anagram(str1, str2):
    list_str1 = list(str1)
    list_str1.sort()
    list_str2 = list(str2)
    list_str2.sort()

    return (list_str1 == list_str2)

print(is_anagram('anagram','nagaram'))
print(is_anagram('cat','rat'))

Sample Output:

True
False

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")
