我有一个包含许多行的信息文件,一些行上有一组数据对。我想提取成对的深度和温度。对在字符64之后开始,每对占用17个字符的空间。
我目前正在做的是切断字符64处的字符串(63用python计数),然后每隔17个字符拆分字符串。 如果对之间存在空白区域,则可以正常工作,但是由于深度较大,因此有些对不会。 以下是示例:
' 1.9901 954.01'
' 1.43011675.01'
临时占用前10个字符,下一个占用深度7.所以我想要的是分割线条,以便我可以分别提取所有值,然后将它们配对。
但是,我在创建一个增加7或10的分割时遇到了问题。另外我不确定python将字符串转换为列表并保留字符长度会发生什么。
这是我的工作代码:
import os, re
import string
with open('TE_feb_2014.pos','r') as file:
for line in file:
m = re.search('(TEMP01)', line)
if m:
values = string.split(line[63:])
#print values
n = 17
[values[i:i+n] for i in range(0, len(values), n)]
print values
以下是一个示例数据行(没有上述问题):

好像你想要这样的东西,
