#Write a function called "num_changer" that accepts a string #of digits (0-9). You should make an integer from the digits #of the even indices and another number from the digits in #the odd indices. Return the sum of these two numbers. You #can assume the given string will have a length of at least #2 digits. # #For example, if the string was "123456", you would split #this into two integers, 135 and 246. Adding them would give #381. Or if the string was "13579", you would split this into #159 and 37, then add them to get 196. # #Hint: You can do this with loops, but it's easier to do #this with string slicing. Remember how we could pass a third #argument to range() that would tell range how many numbers #to skip? You can do something similar with string slices: if #you include second colon in a string slice, the number #that follows it lets you skip characters in the string. For #example: # # "Hello, world!"[1:9] -> This gives "ello, wo". # "Hello, world!"[1:9:2] -> This gives "el, w". Including :2 # in the string slice skips every other letter. # "Hello, world!" [::3] -> This gives "Hl r!". Leaving the # first two spots blank tells it to look at the entire # string, but putting :3 at the end says to only take # every third character (H, l, space, r, and !). # #Hint 2: Remember, Python is zero-indexed. That means the #first number in the string is at position 0, and so it goes #in the even list.
