Question

Create a new program in Mu and save it as ps4.5.2.py and take the code below and fix it as indicated in the comments:

# Do not change the line of code below. It's at the top of
# the file to ensure that it runs before any of your code.
# You will be able to access french_dict from inside your
# function.
french_dict = {"me": "moi", "hello": "bonjour", 
               "goodbye": "au revoir", "cat": "chat", 
               "dog": "chien", "and": "et"}

# Write a function called french2eng that takes in one string
# parameter called sentence. french2eng should look at each
# word in the sentence and translate it into French if it is
# found in the dictionary, french_dict. If a word is not found
# in the dictionary, do not translate it: use the original
# word. Then, the function should return a string of the
# translated sentence.
#
# You may assume that the sentence you're translating has no
# punctuation. However, you should convert it to lower case
# before translating.
#
# For example:
#
#  french2eng("Hello it's me") -> "bonjour it's moi"
#
# Hint: Use .split() to get a list of strings representing
# each word in the string, then use ' '.join to merge the
# translated list back into one string.
#
# Hint 2: Remember, lists are mutable, so we can change
# individual items in the list. However, to change an item
# in a list, we must change it using its index. We can
# write lines like my_words[1] = new_word.
#
# Hint 3: If you're stuck, try breaking it down into small
# parts. How do you access an item from a list? How do you
# look up a key in a dictionary? How do you change the
# value of an item in a list? How do you check if a key is
# in the dictionary?

# Write your function here!

# Below are some lines of code that will test your function.
# You can change the value of the variable(s) to test your
# function with different inputs.
#
# If your function works correctly, this will originally
# print: bonjour it's moi
print(french2eng("Hello it's me"))

Answer 1

french_dict = {"me": "moi", "hello": "bonjour",
"goodbye": "au revoir", "cat": "chat",
"dog": "chien", "and": "et"}

def french2eng(s):

   s=s.split()   #splitting the string to list of words

   for i in range(0,len(s)):   #accessing each wprd in the list
       key=s[i].lower()   #converting each word to lowercase
       if key in french_dict.keys():   #if word is in dictionary
           s[i]=french_dict[key]   #change the word in list to it's corresponding value

   s=" ".join(s)   #join the list with a space
   return s    #return the string

print(french2eng("Hello it's me"))
print()
print(french2eng("Dog and cat"))
