```
 rdict = {}
    f = open(filename)
    for line in f: 
        d = line.split()
        name = d[0]
        rating = int(d[2])
        if name in rdict:
            pass
        else: 
            zlist = []
            for i in range[150]:
                rdict[name] = #a list of ratings

```

I would like to add values (from data given outside of this!) to rdict from the range 150. What would I set rdict equal to?
