列表操作:

>>> movies= [‘the holy grail‘,‘the life of brain‘,‘the  meaning of life’]
>>> movies.insert(1,1975)
>>> movies.insert(3,1979)
>>> movies.append(1983)
>>> movies
[‘the holy grail‘, 1975, ‘the life of brain‘, 1979, ‘the meaning of life‘, 1983]

列表遍历:

>>> for movie in movies:
    print movie

>>> count = 0
>>> while count < len(movies):
print movies[count]
count++

SyntaxError: invalid syntax(不支持++)

>>> while count < len(movies):
print movies[count]
count = count + 1
