python中数组，元组，字典和字符串之间的转换

>>> mytuple = (1,2,3)
>>> print list(mytuple)           # Tuple to list
[1, 2, 3]
>>>
>>> mylist = [1,2,3]              # List to tuple
>>> print tuple(mylist)
(1, 2, 3)
>>>
>>> mylist2 = [ ('blue',5), ('red',3), ('yellow',7) ]
>>> print dict(mylist2)           # List to dictionnary
{'blue': 5, 'yellow': 7, 'red': 3}
>>>
>>> mystring = 'hello'
>>> print list(mystring)          # String to list
['h', 'e', 'l', 'l', 'o']
>>>
>>> mylist3 = ['w','or','ld']
>>> print ''.join(mylist3)        # List to string
world
