The "Create DataFrame with a MultiIndex" code example in the cheatsheet contains an extra bracket
The code example shown for "Create DataFrame with a MultiIndex" in the cheatsheet is incorrect as it contains an extra trailing bracket:

```python
df = pd.DataFrame(
          {"a" : [4 ,5, 6], 
           "b" : [7, 8, 9], 
           "c" : [10, 11, 12]},    index = pd.MultiIndex.from_tuples(
          [('d',1),('d',2),('e',2)],
             names=['n','v'])))
```
It should read:

```python
df = pd.DataFrame(
          {"a" : [4 ,5, 6], 
           "b" : [7, 8, 9], 
           "c" : [10, 11, 12]},    index = pd.MultiIndex.from_tuples(
          [('d',1),('d',2),('e',2)],
             names=['n','v']))
```
