def word_reverser(phrase):

while i >= 0: #iterating from last element in l to first element

# Here is my solution:
def word_reverser(phrase):
splitPhrase= phrase.split(' ')
newPhraseArr = [ ]
for x in range(len(splitPhrase) - 1, -1, -1):

I feel like my code can probably be optimised to remove some variables that were not used.
def word_reverser(phrase):
listy = []
counter = 0
dicty = {}
output = []
for i in range(0, len(phrase)):
if phrase[i] == ' ':
listy.insert(0, phrase[i])
dicty[counter] = listy
counter += 1
listy = []
if i == len(phrase)-1:
listy.append(phrase[i])
dicty[counter] = listy
listy = []
if phrase[i] != ' ':
listy.append(phrase[i])
string = ''
for j in range(0, len(dicty)):
k = len(dicty)-j-1
for l in range(0, len(dicty[k])):
string += dicty[k][l]
continue
return string
print(word_reverser('Hello everybody, my name is Sally Cowboy and Imma cowboy!'))
I have decided to do everything more manually, without using many methods
def word_reverser(phrase):
words = list()
word = ""
for index, let in enumerate(phrase):
if let == " " or index == len(phrase):
words.insert(0, word)
word = ""
else:
word = word + let
if index == len(phrase)-1:
words.insert(0, word)
return " ".join(words)
print(word_reverser('Codecademy rules'))
def word_reverser(phrase):
phraseList = phrase.split();
reverseList = []
for x in range(len(phraseList)):
reverseList.insert(-(len(phraseList)), phraseList [x])
return " ".join(reverseList)
print(word_reverser('Codecademy rules and I am very happy'))
def word_reverser(phrase):
# Write your code here
revPhrase = ''
phraseList = phrase.split()
i = 0
for i in range(len(phraseList)):
i = i + 1
if i == len(phraseList):
revPhrase = revPhrase + phraseList[-i]
else:
revPhrase = revPhrase + phraseList[-i] + ' '
return revPhrase
print(word_reverser('Codecademy rules'))
print(word_reverser("May the Fourth be with you"))
create a variable for the reversed phrase
split the provided phrase in a list
set i to 0
iterate through the list of words and but them together in the revPhrase variable beginning with the last word in the list
If the word from the list is the first(last for our reversed phrase) I don’t add a space behind.
I’m just starting with Python, so it isn’t the cleanest code you will see here
def word_reverser(phrase):
old_sentence = phrase.split() # to separate words
new_sentence = “”
for word in old_sentence:
new_sentence = word+’ '+new_sentence # joining words again in reverse order
return new_sentence[:-1] # this is to eliminate the offending space at the end
