The purpose of this challenge is to gain proficiency with manipulating lists.
Write and submit a Python program that accepts a string from the user and prints it back in three different ways:
- With all letters in reverse.
- With words in reverse order, but letters within each word in the correct order.
- With all words in correct order, but letters reversed within the words.
Output of your program should look like this:
Please enter a string of text (the bigger the better): There are a few techniques or tricks that you may find handy
You entered "There are a few techniques or tricks that you may find handy". Now jumble it:
ydnah dnif yam uoy taht skcirt ro seuqinhcet wef a era erehT
handy find may you that tricks or techniques few a are There
erehT era a wef seuqinhcet ro skcirt taht uoy yam dnif ydnah
There are a few techniques or tricks that you may find handy when working on this challenge. If you see something here that sounds useful, feel free to learn more about it! You don't necessarily need any of these techniques to solve the challenge.
'a string has several characters'.count('a')
will return 5, which is the number of times the character'a'
appears in the string:'a string has several characters'
.zip([1,4,2],['a','z','q'])
will return an iterator for a list of tuples (another type of list) like this:[(1, 'a'), (4, 'z'), (2, 'q')]
- If mylist is a list like
[435, 2, 45, 2]
thenmylist.sort()
will change it to:[2, 2, 45, 435]
- If mylist is a list like
[435, 2, 45, 2]
thenmylist.append(99)
will change it to:[435, 2, 45, 2, 99]
- If mylist is a list like
[435, 2, 45, 2]
thenmylist[-1]
will return2
, the last element in the list. - You can get the length of a string, or number of elements in a list using the
builtin
len()
function. For example:len([435, 2, 45, 2])
will return4
. - If you
import string
then usestring.ascii_lowercase
to get a string with the letters a-z in it.
