Question

Write a program that replaces words in a sentence. The input begins with word replacement pairs (original and replacement). The next line of input is the sentence where any word on the original list is replaced.
Ex: If the input is:

automobile car children kids manufacturer maker The automobile manufacturer recommends car seats for children if the automobile doesn't already have one.

then the output is:
The car maker recommends car seats for kids if the car doesn't already have one.
You can assume the original words are unique.

Answer 1

Answer:

Following are the program in the Python Programming Language

#set variable to input sentence to replace words

sen = input()

#split that sentence

sen = sen.split()

#set variable to input whole sentence

get = input()

#set the for loop to replace words

for i in range(0, len(sen), 2):

 #check condition when words of sen is in get

 if sen[i] in get:

   #then, replace words

   get = get.replace(sen[i], sen[i+1])

#print the whole string after replacing

print('\n',get)

Explanation:

Following are the description of the program.

• Set a variable 'sen' that get a sentence for replacing the word.
• Split that sentence by split() method and again store that sentence in the following variable.
• Set a variable 'get' that gets the whole sentence from the user.
• Set the for loop for replacing words then, set the if conditional statement that checks the condition that the variable 'sen' in the variable 'get' then replace the words.
• Finally, print the whole sentence after the replacement.
