EOFError: EOF when reading a line

def simple_encoder(s):
    users_string = input("please enter a scentence to encode")
    users_stringlower = users_string.lower()
    encodedstr = users_string
    for x in range(0, len(users_string)):
        indexnumber = 0
        count = users_stringlower.count[indexnumber]
        LetterToEncode = users_string[indexnumber]
        if count > 1:
            encodedstr = encodedstr.replace(LetterToEncode, ']')
        elif count == 1:
            encodedstr = encodedstr.replace(LetterToEncode, '[')
        indexnumber = indexnumber + 1

Usually, EOFError refers to an End Of File error . That means that your program called input() but failed to have any available input to read.

We cannot run the code you posted because we're missing some variables, like NumOfIterations .
