if-elif-else coding help

In addition, there should be a colon at the end of the if statement: if len(mystr) < 6:.
Furthermore, your quote characters are not actually quote characters. They're some sort of weird multi-byte horror, similar to the trash Microsoft Word frequently replaces quotes for. To demonstrate, here's a single quote character x, and the two different make-believe nonsense characters you had (they are NOT the same, and it DOES matter):

>>> x = "'"
>>> x.encode()
b"'"
>>> y = "‘"
>>> y.encode()
b'\xe2\x80\x98'
>>> z = '’'
>>> z.encode()
b'\xe2\x80\x99'
