Objective
Develop a Python program that prompts the user to input multiple sentences, stopping when they press Enter without typing anything. The program should save these sentences in a text file called "sentences.txt." If the file already exists, the program must append the new input to the end of the existing content.

def collect_and_save_sentences():
"""
Collects multiple sentences from the user and saves them to a file.
If the file already exists, appends the new sentences to the end.
Stops when the user presses Enter without typing anything.
"""
sentences = []
print("Enter sentences. Press Enter without typing anything to finish.")
while True:
sentence = input("Enter a sentence: ")
# If the user presses Enter without typing anything, stop collecting sentences
if not sentence:
break
# Add the sentence to the list
sentences.append(sentence)
# Append the sentences to 'sentences.txt', creating the file if it doesn't exist
with open("sentences.txt", "a") as file:
for sentence in sentences:
file.write(sentence + "\n")
print(f"\n{len(sentences)} sentences were added to 'sentences.txt'.")
if __name__ == "__main__":
collect_and_save_sentences()
Output
Enter sentences. Press Enter without typing anything to finish.
Enter a sentence: First sentence.
Enter a sentence: Another sentence.
Enter a sentence:
2 sentences were added to 'sentences.txt'.
