Answer 1

You’re using a twice.

  = []
       :
     ( ( ))
      =  ( ) # Here is overwritten!
     . ( )#

results = []
       :
    df =  ( )
     ( (df))
    results. (df)

Answer 2

The issue here is the reassignment of the a value on line 2 in the for loop.

You need to use a different variable name.

  = []
       :
     ( ( ))
    x =  ( )
     . (x)

Notice how we dont now change a in each loop.
