# In 1939 Ernest Vincent Wright published a 50,000 word novel called Gadsby that does not contain the letter "e."
# Since "e" is the most common letter in English, that’s not easy to do. In fact, it is difficult to construct a
# solitary thought without using that most common symbol. It is slow going at first, but with caution and hours of
# training you can gradually gain facility. All right, I’ll stop now. Write a function called has_no_e that returns
# True if the given word doesn’t have the letter "e" in it.
def has_no_e(s):
    if 'e' not in s:
        return True
    else:
        return False

string=input("Enter a string : ")
check_e=has_no_e(string)
if check_e:
    print(string,"has no 'e' letter")
else:
    print(string,"has 'e' letter")
