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 24

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")
