Question

What is the pythonic way to doing this?

From this: ‘This is a string to try’ to this: ‘try to string a is This’

My first guess was:

for w in 'This is a string to try'.split(' ')[::-1]:
    print w,

but str.split() is not allowed. Then I came up with this:

def reverse_w(txt):
    tmp = []
    while (txt.find(' ') >= 0):
        tmp.append(txt[:txt.find(' ')])
        txt = txt[txt.find(' ')+1:]
    if (txt.find(' ') == -1):
        tmp.append(txt)
   return tmp[::-1]

Answer 1

def reverse(sentence):
sentence = 'This is a string to try'
    answer = ''
    temp = ''
    for char in sentence:
        if char != ' ':
            temp += char
        else:
            answer = temp + ' ' + answer
            temp = ''
    answer = temp + ' ' + answer
    return answer.rstrip(' ')
