根據另一個列表Python中的字符串僅輸出txt文件中的特定項目

Question

我有一個字符串列表：

myStrings = [Account,Type, myID]

我還有一個txt file其中包含與這些字符串關聯的numbers ，例如：

[90: 'Account', 5: 'Type', 6: 'MyID', 8: 'TransactionNum', 9: 'Time']

如何only the numbers and strings in the txt file打印only the numbers and strings in the txt file in myStrings only the numbers and strings in the txt file 。 例如，由於'Time' is not in myStrings ，我do not want to print it 。 我也想讓這個txt file a list

Answer 1

在你說文件沒有[ & ] ，可以讓它像這樣工作：

import json
myStrings = ['Account','Type', 'myID']

with open('text-file.txt') as filename:
  file_text = filename.read()


file_text_list = file_text.split(',')
file_text_dict = {}
for item in file_text_list:
  k, v = item.split()
  v = v.replace("'", "")
  k = k.replace(":", "")
  if v in myStrings:
    file_text_dict[k] = v
print(file_text_dict)  # output => {'90': 'Account', '5': 'Type'}
print(list(file_text_dict.values()))  # output => ['Account', 'Type']

Answer 2

這應該可以幫助你：

myStrings = ['Account','Type', 'myID']
f = open("D:\\Test.txt","r")
txt = f.read()
f.close()

txt = txt.replace('\n',' ')

txt = txt.split(',')

txtlst = []
for x in txt:
    txtlst.append(x.split(':'))

numslst = [int(txtlst[i][0]) for i in range(len(txtlst))]

strlst = []

for i in txtlst:
    for j in i:
        try:
            int(j)
        except ValueError:
            strlst.append(j.replace("'",""))

for x in range(len(strlst)):
    strlst[x] = strlst[x].replace(' ','')

for x in range(len(strlst)):
    if strlst[x] in myStrings:
        print(numslst[x])
        print(strlst[x])

輸出：

90
Account
5
Type
