   ### What did you expect to see?
   
   For Redis:
   ```
   127.0.0.1:6379> sscan set1 0
   1) "1"
   2)  1) "e"
       2) "o"
       3) "q"
       4) "h"
       5) "t"
       6) "a"
       7) "m"
       8) "d"
       9) "u"
      10) "b"
      11) "v"
   127.0.0.1:6379> sscan set1 1
   1) "7"
   2)  1) "x"
       2) "w"
       3) "i"
       4) "c"
       5) "s"
       6) "g"
       7) "r"
       8) "l"
       9) "p"
      10) "n"
      11) "k"
   127.0.0.1:6379> sscan set1 7
   1) "0"
   2) 1) "f"
      2) "j"
      3) "z"
      4) "y"
   127.0.0.1:6379>
   ```
   As we can see: cursor always is number. Moreover, the Python and Go 
libraries expect the cursor value to be represented as an integer. And of 
course code break when the cursor is not converted to a number.
