我有一个txt文件，我想创建一个数组

Question

我有一个这样写的txt文件：（enter image description here）

  speed weight  color fuel   cost
0   180      3  black   95    NaN
1   160    NaN  green   92    NaN
2   200      5    NaN   95    NaN
3   180      3  black   95  30000

我想创建一个像这样的数组

import re
import pandas as pd

df_output_list  = {}
df_output_dict  = []
match_counter = 1

with open('sample_car.txt',encoding='utf-8') as file:
    line = file.readline()
    while line:

        result = re.split(r'\|',line.rstrip())
        result2 = re.findall(r'.(?<=\[)(\d+)(?=\])',result[1])

        regex = re.compile('vechicle.car.characteristics.')
        match = re.search(regex, result[1])
        if match:

            if match_counter == 1:
                ArrInd = 0
            match_counter+=1
            #print(df_output_list)
            if ArrInd == int(result2[0]):
                df_output_list[result[1].split('.')[3]] = result[2]
                ArrInd = int(result2[0])

            else:
                df_output_dict.append(df_output_list)
                df_output_list  = {}
                df_output_list[result[1].split('.')[3]] = result[2]
                ArrInd = int(result2[0])

        line = file.readline()
    df_output_dict.append(df_output_list)
#print(df_output_dict)
df_output = pd.DataFrame(df_output_dict)
print(df_output)

这就是我得到的：

1 !
2 "
3 #
4 $
5 %
