I want to cluster two column names customerid (cid) and state:

```
cid = np.array(b.customerID)
state = np.array(b.State)
pd.crosstab(ind, [cid, state], rownames=['cid'], colnames=['state'], dropna = False)

```

When I try to create crosstab in Python its showing me that 

> 
> arrays and names must have the same length

Anyone please help me.
