Who can help me to understand the next code about yield?

Question

def make_word():
word=""
for ch in "spam":
word+=ch
yield word
print(list(make_word))

Answer 1

Output is ['s', 'sp', 'spa', 'spam'], if you fix the syntax. If you iterate over a string, you get it char by char. These chars are appended to word, which is yielded.

Answer 2

I don‘t understand the output -['spam', 'spam', 'spam', 'spam'], how the itera runs?

Answer 3

see my sample of using a generator. it helps to understand yield statement.

Answer 4

Your code just works fine! I have tried printing with an additional parentheses for make_word as make_word().

#print(list(make_word()))

def make_word():
word=""
for ch in "spam":
word+=ch
yield word

print(list(make_word()))
