I added some content, functionality and comments
Hope this is helpful
Comments appreciated
Write your code below:
from contextlib import contextmanager
@contextmanager
def generic(card_type, sender_name, recipient_name):
card_file = open(card_type, ‘r’)
new_card_order = open(f"{sender_name}_generic.txt", ‘w’)
try:
new_card_order.write(f"Dear {recipient_name},\n")
new_card_order.write(card_file.read()+"\n")
new_card_order.write(f"\nSincerely, \n{sender_name} \n")
yield new_card_order
finally:
card_file.close()
new_card_order.close()
print(“Task 1”)
print(“Generating a ‘generic’ THANK YOU card using a decorator containing a generator function based context manager and the provided ‘thankyou_card.txt’ file.”)
print()
with generic(“thankyou_card.txt”, “Mwenda”, “Amanda”) as new_card:
print(“Card Generated! \n”)
with open(“Mwenda_generic.txt”, “r”) as new_card1:
print(new_card1.read())
print(“Starting Task 2”)
print("(It really bothered me to not see the end result of creating an instance object of the class approach context manager, so I added some functionality to include a with statement, an additional variable name and a print statement to read() it, instead of just seeing the object itself, below.)")
print()
print("(I learn better if I confirm the intended output of the code block.)")
print()

print(“TYPO found in the provided text files for John and Josiah. There is a comma after the sender name that is grammtically incorrect so I removed it from both files.”)
