Check 3.3
Write a function called everyThirdCharacter(s) which takes in a string s and returns a new string which only contains every third character from s. For example, everyThirdCharacter("abcdefghijk") should return "adgj". Note that there are several ways to solve this! Pick any of them!
Hint: A useful programming pattern for strings is "building up a new string". Here's an example code snippet which uses that strategy. Think about how you can apply this kind of logic to the next few checks.
def removeSpaces(s):
newString = ""
for c in s:
if c != " ": newString += c
return newString
def everyThirdCharacter(s):
return 42
print(everyThirdCharacter("Nokiabcd etc Fiji oO0b?%!"))
