Please Check and Help me !?

I am getting wrong answer in second last assert.

to me it is problem in test condition ! Is there is something that is missing from question ? def to_encrypt(text, delta):

cipher = '' for char in text: if char == ' ': cipher = cipher + char elif char != ' ': cipher = cipher + chr((ord(char) + delta - 97) % 26 + 97) else: cipher = cipher + chr((ord(char) + delta - 122) % 26 + 122)

return cipher

if name == 'main': print("Example:") print(to_encrypt('abc', 10))

#These "asserts" using only for self-checking and not necessary for auto-testing
assert to_encrypt("a b c", 3) == "d e f"
assert to_encrypt("a b c", -3) == "x y z"
assert to_encrypt("simple text", 16) == "iycfbu junj"
assert to_encrypt("---------rtant text", 10) == "swzybdkxd dohd" <<<<---------My output is " kkkkkkkkkbdkxd dohd "
assert to_encrypt("state secret", -13) == "fgngr frperg"
