我是 python 脚本的新手。请如何过滤和导出该行到一个新的文本文件

Question

请问我如何编写python代码以仅从文本文件中提取电话号码。 然后将提取保存在另一个文本文件中。

文本文件示例：

"Name": Farouk, "Age": 23, "Address": No. 582, Chile crescent, Kenya, "Phone number": 231765987
"Name": Ben, "Age": 23, "Address": No. 582, Chile crescent, Kenya, "Phone number": 21690860

Answer 1

假设实际上有一个换行符 "\\n" 在, "Phone number": 231765987 "Name": Ben,

喜欢：

"Name": Farouk, "Age": 23, "Address": No. 582, Chile crescent, Kenya, "Phone number": 231765987 
"Name": Ben, "Age": 23, "Address": No. 582, Chile crescent, Kenya, "Phone number": 21690860

这可以解决问题：

with open("./data.txt") as read_file: # The file being read
    with open("./Phone Numbers.txt", 'w') as write_file: # New file being created
        for data in read_file:
            for d in data.strip("\n").split(','):
                if "Phone number" in d:
                    write_file.write(d[16:].strip(" ") + "\n")

Answer 2

作为初步建议，您应该在寻求帮助之前编写一些代码。 如果您共享一些代码，其他人将直接开始解决您的问题。

要解决这个问题，首先需要逐行读取文件。 如果每一行都包含您在问题中粘贴的文本，您可以使用正则表达式来搜索电话号码。 您也可以将此字符串转换为 JSON，但由于地址没有引号，因此格式无效。 所以最好使用正则表达式来解决这个问题。

查找示例代码来解决这个问题

import re
content = []
file_name = 'sample'
with open(file_name) as f:
    content = f.readlines()

for line in content:
    m = re.search("\"Phone number\": (\w+)", line)
    if m is None:
        print("There is no success for search.")
    else:
        print(m.groups()[0])

Answer 3

import glob
import errno
import csv
import re
i = 0
path = 'C:/Users/Mallam Farouk Sanusi/Desktop/k/*.txt'
files = glob.glob(path)
for name in files:
try:
    with open(name) as f:
        csv.field_size_limit(1310720)
        s = csv.reader(f)
        for line in s:
            print (line[9])

        i = i+1
