list 與 tuple 比較

1. list 與 tuple 變更元素內容比較。

   [dywang@deyu zzz]$ cat tuple2.py
   #!/usr/bin/python3
   # coding: utf-8
   
   listx = [ 32, 12, 'abc' ]
   tuplex = ( 32, 12, 'abc' )
   listx[1] = 10
   tuplex[1] = 10
   

2. 執行結果：list 可以變更元素內容，tuple 變更元素內容會出現錯誤。

   [dywang@deyu zzz]$ ./tuple2.py 
   Traceback (most recent call last):
     File "./tuple2.py", line 7, in <module>
       tuplex[1] = 10
   TypeError: 'tuple' object does not support item assignment
