Question

从 Unix 目录读取多个文件。我正在尝试读取存储在 Unix 文件夹中的多个文件，并在这段文本“input1”之后提取键值对。

每个文件包含以下格式的数据：-

input1 = {'hostname' : 'host', 'port' : '22', 'basedn' : 'CN=Users', 'bindusername' : 'admin']

Need to read dict and extract Key Value pair and print in below format:
    
    Col1   Col2
    xyz   123
    abc   456
    def   756



path = '/home/var/testfile/'
basepath =os.path.dirname(path)
with os.scandir(basepath) as entries:
        for entry in entries:
            if entry.is_file():
               fn=entry.name
def f(fn):
     with open(fn) as f:
        for s in f:
            data = pd.DataFrame()
            key = []
            value = []
            for k, v in s.items():
                key.append(k)
                value.append(v)
            data["Col1"] = key
            data["Col2"] = value
            print(data)
            
Above script does wotk when for a single file , but when i loop to read all the files from the folder , it stucked .

Answer 1

import pandas as pd

dic = {'xyz':'123' , 'abc':'456','def':'765'}
data = pd.DataFrame()
key = []
value = []
for k, v in dic.items():
    key.append(k)
    value.append(v)
data["Col1"] = key
data["Col2"] = value
print(data)

Answer 2

试试这个？

import pandas as  pd
dic1={'xyz':'123' , 'abc':'456','def':'765'}
data = pd.DataFrame()
data['Col1']=[val for val,key in dic1.items()] #=== All keys in dic1
data['Col2']=[key for val,key in dic1.items()] #=== All Values in dic1
print(data)

印刷品：

  Col1 Col2
0  xyz  123
1  abc  456
2  def  765
