Question

Using Python

Answer 1

Answer:

#section 1

import re

thesaurus = {

   "happy" : "glad",

   "sad" : "bleak",

   }

text =input('Enter text: ').lower()

#section 2

def synomReplace(thesaurus, text):

# Create a regular expression  from the dictionary keys

 regex = re.compile("(%s)" % "|".join(map(re.escape, thesaurus.keys())))

 

 # For each match, look-up corresponding value in dictionary

 return regex.sub(lambda x: thesaurus[x.string[x.start():x.end()]].upper(), text)

print(synomReplace(thesaurus, text))

Explanation:

#section 1

In this section, the regular expression module is imported to carry out special string operations. The thesaurus is initialized as a dictionary. The program then prompts the user to enter a text.

#section 2

In the section, we create a regular expression that will search for all the keys and another one that will substitute the keys with their value and also convert the values to uppercase using the .upper() method.

I have attached a picture for you to see the result of the code.
