list 和 str 的最大區別是:

list是可變的，str是不可變的

e.g list.append('test) #這個是允許的

teststr='test'

teststr[1]='a'

返回TypeError: 'str' object does not support item assignment

區別2：list是多維的，

e.g

listMulti=[[1,2],[3,4]]

list和str的轉換：

teststr='Hello I like Python'
testList=teststr.split()
print testList


teststr='Hello, I like Python'
testList=teststr.split(',')
print testList

 

分別返回：['Hello', 'I', 'like', 'Python']

	['Hello', ' I like Python']

split(...) S.split([sep [,maxsplit]]) -> list of strings
Return a list of the words in the string S, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits
are done. If sep is not specified or is None, any whitespace string is a separator and empty strings are removed from
the result.
 

join是split的相反方法

jointest=''.join(teststr)
print jointest

返回： Hello, I like Python
list的解析功能很有用(簡潔優雅的Python): 求平方：

squares = [x**2 for x in range(1,10)]
print squares

返回：[1, 4, 9, 16, 25, 36, 49, 64, 81]
求100以內能被3整除的數

aliquto = [n for n in range(1,100) if n%3==0]
print aliquto

return [3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99] 更優的實現： range(3,100,3)
