I'm sure this isn't very pythonic; comments and advice appreciated
def curious(text):
""" Return the words in input text scrambled except for the first and
last letter. """
new_text = ""
word = ""
for ch in text:
if ch in "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ":
word = word + ch
else:
new_text = new_text + scramble(word)
word = ""
new_text = new_text + ch
return new_text
def scramble(word):
""" scramble word """
from random import randint
if len(word) < 4:
return word
new_word = word[0]
### transform "curious" into ['u', 'r', 'i', 'o', 'u']
letters = []
for ch in word:
letters.append(ch)
del letters[0:1]
del letters[-1]
### why doesn't range(len(letters) - 1, 0, -1) work?
for i in range(len(letters) - 1, -1, -1):
j = randint(0, i)
new_word = new_word + letters[j]
del letters[j]
return new_word + word[-1]
print curious(curious.__doc__)
