我是新来的Python 我有一个像这个的字符串
Temp = " , /1412311.2121
"
我所期望的输出只是获得数字和小数数本身,所以我在找
1412311.2121
as the output.. trying to get rid of the , / in the string.. I have tried Temp.strip(" ") and Temp.rstrip(" ") for trying to remove but i still seems to remain in my string. :/... Does anyone have any ideas? Thanks for your help.
字符串是不可更改的。 string.strip () doesn't change string ,这是一个返回值的函数。 您需要做到 :
Temp = Temp.strip()
Note also that calling strip() without any parameters causes it to remove all whitespace characters, including
As stalk said, you can achieve your desired result by calling strip(" ,/
") on Temp.
我会用一个固定的表达方式来做这个:
In [8]: s = " , /1412311.2121
"
In [9]: re.findall(r ([+-]?d+(?:.d+)?(?:[eE][+-]d+)?) , s)
Out[9]: [ 1412311.2121 ]
此返回在字符串中发现的所有浮点数列表 。
如果数据与您所显示的相同,则用非数字数据包扎的左右数字,您可以使用非常简单的正则表达式:
g = re.search( [0-9.]+ , s) # capture the inner number only
print g.group(0)
