根据另一个列表中的字符串仅输出 txt 文件中的特定项目 Python

Question

我有一个字符串列表：

myStrings = [Account,Type, myID]

我还有一个 txt file 和 numbers 与这些字符串相关联，例如：

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

如何打印 only the numbers and strings in the txt file 是 in myStrings。例如，由于'Time' is not in myStrings，我do not want to print it。我也想做这个txt file a list

Answer 1

在你说文件没有 [ & ] 之后，可以让它像这样工作:

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

这应该对你有帮助：

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])

输出：

90
Account
5
Type
