In the following

• s is the string 'peter piper picked a peck of pickled peppers.';
• s.split() returns a list of the "words" in the string s where "words" are separated by whitespace: ['peter', 'piper', 'picked', 'a', 'peck', 'of', 'pickled', 'peppers.'] (docs);
• reversed(s.split()) returns a reverse iterator over the list s.split() (docs);
• next(it).rstrip('.') returns the first element in the iterator, stripping the period from this element: 'peppers' (docs); we print this out (without ending the print with a newline, which print does by default);
• we loop over the remaining elements in the iterator, printing them out (preceded by a space character and without ending the print with a newline).

s = 'peter piper picked a peck of pickled peppers.'
it = reversed(s.split())
print(next(it).rstrip('.'), end = "")
for i in it:
     print(f" {i}", end = "")
print('.')

Output

peppers pickled of peck a picked piper peter.

Split, reverse and join:

s = 'peter piper picked a peck of pickled peppers.'

print(' '.join(reversed(s.split())))

CodePudding user response：

sentence = "peter piper picked a peck of pickled peppers."
#split string by single space
chunks = sentence.split(' ')

s = " "
rev = s.join(reversed(chunks))
  
print(rev)

Hope this helps
