Splitting strings in Python without split()

Question

What are other ways to split a string without using the split() method? For example, how could [\'This is a Sentence\'] be split into [\'This\', \'is\', \'a\', \'Sentence\']

Answer 1

sentence = 'This is a sentence'
word=""
for w in sentence :
    if w.isalpha():
        word=word+w

    elif not w.isalpha():
      print(word)
      word=""
print(word)
