Answer in Python for kika #283508
Write a function called missing_letters that takes a string parameter and returns a new string with all the letters of the alphabet that are not in the argument string. The letters in the returned string should be in alphabetical order.
Your implementation should use a histogram from the histogram function. It should also use the global variable alphabet. It should use this global variable directly, not through an argument or a local copy. It should loop over the letters in alphabet to determine which are missing from the input parameter.
The function missing_letters should combine the list of missing letters into a string and return that string.
alphabet = ‘abcdefghijklmnopqrstuvwxyz’
test_miss = [“abcd”, “fgmnor”]
hist = 
for i in alphabet:
if not((i in s) or (i.upper() in s)):
ans = histogram(foo)
ans = ”.join(ans)
print(“It uses all the letters”)
for i in test_miss:
print(“Calling the function test_miss: n”)
