Python 3.3 Tuple、Exception and Tuple vs. List

import sys

#Tuples
t = "1", "2", "3", 1, [123], {123545}
print(t, " length", len(t))

try:
 t[0] = "7"
except Exception as e:
 print(sys.exc_info())
 print("\n\n", e, "\n")

#Clear
t = ()
t = "ads","dasds"
print(t, " length", len(t))

x,y = t
print(x,y)

Tuple vs. List
Tuple：值是不可變動，Tuple像Struct能有不同型態
List：值是可變動，每個List只能使用一種型態
