python读文本处理小结一下！

output.txt 内容
helo:word
qwe:rtgbh52800op
poil:7851fghjj874

file=open("output.txt")
lines=file.read()
for str in line.split("\n"):
    word=str.split(":")
    print word[0]

打印以“：”间隔的第一列的数据！


string 模块测试
>>>string.atof("12.2")
12.199999999999999

>>> s = 'mary had a little lamb'
";".join(string.split(s))

把字典查分成列表
>>> params={"aaa":"ddd","ccc":"fdsa"}
>>> params.items()
