1.python報錯：TypeError: 'int' object is not subscriptable
subscriptable：可以使用下表來訪問資料
- 此報錯一般是在整數上加了下標
In [20]: a = [("a","b"),("c","d"),"e"]
In [21]: a[2][0]
Out[21]: 'e'
In [22]: a[2][1]
---------------------------------------------------------------------------
IndexError Traceback (most recent call last)
<ipython-input-22-2e4ed419d949> in <module>()
----> 1 a[2][1]
IndexError: string index out of range
In [23]: a = [("a","b"),("c","d"),3]
In [24]: a[2][0]
