我是python脚本的新手.请问我如何过滤该行并将其导出到新的文本文件

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, "Phone number": 231765987 "Name": Ben,之间实际上有一个换行符""

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

这将解决问题：

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

作为最初的建议，你应该在寻求帮助之前编写一些代码。如果您共享一些代码，其他人将直接开始处理您的问题。

为了解决这个问题， 首先，您需要逐行读取文件。 如果每一行都包含您粘贴到问题中的文本，则可以使用正则表达式搜索电话号码。 您也可以将此字符串转换为 JSON，但没有有效的格式，因为地址没有引号。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此问题

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])

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
