6. Decorators - 6

1. Chain two decorators with the greet function as shown in the following code.

2. Run the code and verify if the HTML tags have been added on both sides of the string.

@bold_tag @italic_tag def greet(): return input()

3. Use the Test against custom input box to output the result for debugging.

4. Provide a string (refer test case samples) to display the output/error.

Given Input:

Python is a programming language

Expected Output:

 
<i><b>Python is a programming language</b></i>

Program:

import os
import sys

def bold_tag(func):    

    def inner(*args, **kwdargs):

        return '<b>'+func(*args, **kwdargs)+'</b>'        

    return inner


def italic_tag(func):    

    def inner(*args, **kwdargs):

        return '<i>'+func(*args, **kwdargs)+'</i>'
        

    return inner
    

#Add greet() implementation here

@italic_tag

@bold_tag

def greet():

    msg=input()

    return msg

    

'''check Tail section below for input / output'''

if __name__ == "__main__":
    with open(os.environ['OUTPUT_PATH'], 'w') as fout:
        res_lst = list()
        res_lst.append(greet())
        fout.write("{}".format(*res_lst))

Output:

 
<i><b>Python is a programming language</b></i>
