# Write your substring_between_letters function here:
def substring_between_letters(word, start, end):
  begain = word.find(start)
  last = word.find(end)
  if begain == -1 or last == -1:
    return word
  else:
    return word[(begain+1):last]

# Uncomment these function calls to test your function:
print(substring_between_letters("apple", "p", "e"))
# should print "pl"
print(substring_between_letters("apple", "p", "c"))
# should print "apple"
