Python解析然后放入数据框

Question

我有一个包含如下数据的文件:

------------------------------
------------------------------
<TIME:2020-01-01 01:25:10> 
<TIME:2020-01-01 01:25:10> 
<TIME:2020-01-01 01:25:10> 
<TIME:2020-01-01 01:25:10>

------
++++++
%%RequestHandler
    DATA1 = 123456
    ERROR1 = 500
    DATA2 = 56789
    ERROR2 = 505

Count = 4
---

我想创建一个像这样的数据框

<表类=“s-表”> <标题> 数据1 错误1 <正文> 123456 500 56789 505

Answer 1

使用 pivot 的另一种正则表达式方法:

import re

                                                         # or file.read()
out = (pd.DataFrame(re.findall(r'^\s+(\w+)(\d+) = (\d+)', text, flags=re.M))
         .pivot(index=1, columns=0, values=2)
         .rename_axis(index=None, columns=None)
      )

print(out)

输出:

     DATA ERROR
1  123456   500
2   56789   505

使用的输入:

text = '''------------------------------
------------------------------
<TIME:2020-01-01 01:25:10> 
<TIME:2020-01-01 01:25:10> 
<TIME:2020-01-01 01:25:10> 
<TIME:2020-01-01 01:25:10>

    DATA2 = 56789
    ERROR2 = 505

Count = 4'''
