[英]Concat every 4 strings from a list?
I have this list: 我有这个清单:
['192', '168', '0', '1', '80', '192', '168', '0', '2', '8080']...
And i want to get this list: 我想得到这个清单:
['192.168.0.1:80', '192.168.0.2:8080']...
What is the best way of doing it ? 这样做的最佳方式是什么?
using range
with list
pop ? 使用
range
与list
弹出?
using list
slicing ? 使用
list
切片?
>>> data = ['192', '168', '0', '1', '80', '192', '168', '0', '2', '8080']
>>> ['{}.{}.{}.{}:{}'.format(*x) for x in zip(*[iter(data)]*5)]
['192.168.0.1:80', '192.168.0.2:8080']
Using starmap
使用
starmap
>>> from itertools import starmap
>>> list(starmap('{}.{}.{}.{}:{}'.format,zip(*[iter(data)]*5)))
['192.168.0.1:80', '192.168.0.2:8080']
This is one way to do it, which may or may not be the "best" way: 这是一种方法,可能是也可能不是“最好的”方式:
>>> a = ['192', '168', '0', '1', '80', '192', '168', '0', '2', '8080']
>>> [":".join([".".join(a[x:x+4]), a[x+4]]) for x in range(0, len(a), 5)]
['192.168.0.1:80', '192.168.0.2:8080']
