Question
(Anagrams) Write a function that checks whether two words are anagrams. Two words are anagrams if they contain the same letters. For example, silent and listen are anagrams. The header of the function is: def isAnagram(s1, s2): (Hint: Obtain two lists for the two strings. Sort the lists and check if two lists are identical.) Write a test program that prompts the user to enter two strings and, if they are anagrams, displays is an anagram; otherwise, it displays is not an anagram.
Answer
Anagrams Program Code:
# Function to check whether two words are anagrams
def isAnagram(s1, s2):
# Convert the strings to lowercase
s1 = s1.lower()
s2 = s2.lower()
# Convert the strings to lists of characters
s1_list = list(s1)
s2_list = list(s2)
# Sort the lists of characters
s1_list.sort()
s2_list.sort()
# Check if the sorted lists are identical
if s1_list == s2_list:
return True
else:
return False
# Test program
def main():
# Prompt the user to enter two strings
wordOne = input("Enter the first word: ")
wordTwo = input("Enter the second word: ")
# Check if the strings are anagrams using the isAnagram function
if isAnagram(wordOne, wordTwo):
print("The words are anagrams.")
else:
print("The words are not anagrams.")
# Call the test program
main()
Executed Output 1:
Enter the first word: silent
Enter the second word: listen
The words are anagrams.
Executed Output 2:
Enter the first word: madam
Enter the second word: dear
The words are not anagrams.
