My program extracts only letters, but not the entire words.
def first_word(sentence):
return sentence[0]
def second_word(sentence):
return sentence[1]
def last_word(sentence):
return sentence[-1]
if __name__ == "__main__":
sentence = "I want to learn python"
print(first_word(sentence))
print(second_word(sentence))
print(last_word(sentence))
The output in example above must be:
I
want
python
CodePudding user response:
sentence.split()
will return a list of all the words that are separated by whitespace:
def first_word(sentence):
return sentence.split()[0]
def second_word(sentence):
return sentence.split()[1]
def last_word(sentence):
return sentence.split()[-1]
if __name__ == "__main__":
sentence = "I want to learn python"
print(first_word(sentence))
print(second_word(sentence))
print(last_word(sentence))
CodePudding user response:
Use str.split
method:
def first_word(sentence):
return sentence.split()[0] # <- HERE
def second_word(sentence):
return sentence.split()[1] # <- HERE
def last_word(sentence):
return sentence.split()[-1] # <- HERE
if __name__ == "__main__":
sentence = "I want to learn python"
print(first_word(sentence))
print(second_word(sentence))
print(last_word(sentence))
Output:
I
want
python
