一字一句

Question

嗨，我正试着分开一段文字

For example
'C:/bye1.txt'
i would want 'C:/bye1.txt' only

'C:/bye1.txt C:/hello1.txt'
i would want C:/hello1.txt only

'C:/bye1.txt C:/hello1.txt C:/bye2 C:/bye3'
i would want C:/bye3 and so on.

我试过的代码，问题是它只打印出Y

x = "Hello i am boey"
Last = x[len(x)-1]
print Last 

Answer 1

看看这个：

>>> x = 'C:/bye1.txt'
>>> x.split()[-1]
'C:/bye1.txt'
>>> y = 'C:/bye1.txt C:/hello1.txt'
>>> y.split()[-1]
'C:/hello1.txt'
>>> z = 'C:/bye1.txt C:/hello1.txt C:/bye2 C:/bye3'
>>> z.split()[-1]
'C:/bye3'
>>>

基本上，使用^{}分割字符串，然后得到最后一项（这就是[-1]所做的）。你知道吗

Answer 2

x = "Hello i am boey".split()
Last = x[len(x)-1]
print Last

虽然更像Python：

x = "Hello i am boey".split()
print x[-1]

Answer 3

尝试：

>>> x = 'C:/bye1.txt C:/hello1.txt C:/bye2 C:/bye3'
>>> x.split()[-1]
'C:/bye3'
>>>
