Question
Attached is a text file called "Test.txt" that I've created for Python:
"There was nothing so very remarkable in that; nor did Alice think it so very much out of the way to hear the Rabbit say to itself,
“Oh dear! Oh dear! I shall be late!” (when she thought it over afterwards,
it occurred to her that she ought to have wondered at this, but at the time it all seemed quite natural);
but when the Rabbit actually took a watch out of its waistcoat-pocket, and looked at it, and then hurried on,
Alice started to her feet, for it flashed across her mind that she had never before seen
a rabbit with either a waistcoat-pocket, or a watch to take out of it, and burning with curiosity,
she ran across the field after it, and fortunately was just in time to see it pop down a large rabbit-hole under the hedge."
I'm trying to create a Markov chain with this code I have here (markov.py) but the program won't run because it doesn't have a direct path to "Test.txt". Can you help me fix this issue?
import random
def is_ending_word(word):
return word[-1] in {'.', '!', '?'}
def read_file(filename):
chain = {}
first_words = []
with open(filename, 'r') as f:
for line in f:
words = line.split()
first_words.append(words[0])
for i in range(len(words) - 1):
if words[i] not in chain:
chain[words[i]] = []
if not is_ending_word(words[i]):
chain[words[i]].append(words[i + 1])
if is_ending_word(words[i + 1]):
if i < len(words) - 2:
first_words.append(words[i + 2])
chain[words[i + 1]] = []
if words and words[-1] not in chain:
chain[words[-1]] = []
return chain, first_words
def generate_sentence(chain, start_lst):
current = random.choice(start_lst)
sentence = [current]
while True:
if chain[current]:
current = random.choice(chain[current])
else:
break
sentence.append(current)
return ' '.join(sentence)
def main():
chain, first_word = read_file('Test.txt')
generated_sentence = generate_sentence(chain, first_word)
print(generated_sentence)
if __name__ == '__main__':
main()
