Python: Make two given strings anagrams removing any characters from any of the strings

Python String: Exercise-66 with Solution

Write a Python program to make two given strings (lower case, may or may not be of the same length) anagrams removing any characters from any of the strings.

Sample Solution:-

Python Code:

def make_map(s):
    temp_map = {}
    for char in s:
        if char not in temp_map:
            temp_map[char] = 1
        else:
            temp_map[char] +=1 
    return temp_map        
def make_anagram(str1, str2):
    str1_map1 = make_map(str1)
    str2_map2 = make_map(str2)
 
    ctr = 0
    for key in str2_map2.keys():
        if key not in str1_map1:
            ctr += str2_map2[key]
        else:
            ctr += max(0, str2_map2[key]-str1_map1[key])
 
    for key in str1_map1.keys():
        if key not in str2_map2:
            ctr += str1_map1[key]
        else:
            ctr += max(0, str1_map1[key]-str2_map2[key]) 
    return ctr 
str1 = input("Input string1: ")
str2 = input("Input string2: ")
print(make_anagram(str1, str2))

Sample Output:

Input string1:  The quick brown fox
Input string2:  jumps over the lazy dog

Previous: Write a Python program to find all the common characters in lexicographical order from two given lower case strings. If there are no common letters print “No common characters”.
Next: Write a Python program to remove all consecutive duplicates of a given string.

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")
