我需要从文件中提取帖子代码，我从谷歌文档下载如下：

我需要提取邮政编码'short_name': '3006'，但不是所有的short_name都跟着邮政编码
我已经厌倦了一些方法，但我只是获得了一些空格，我曾经使用过带语言
import re
hand = open('data')
for line in hand:
#print line
line = line.rstrip()
stuff = re.findall('^\'short_name\':([0-9]+)',line)
print stuff
我得到的结果是：
[]
Process finished with exit code 0
我修理了它，就像那样：它们之间有太多的空间，
import re
hand = open('data')
for line in hand:
line = line.rstrip()
stuff = re.findall(r'\'short_name\':\s*\'([0-9]{4})\'',line)
#stuff = re.findall(r'\'short_name\':([0-9]{4})',line)
print stuff
答案 0 :(得分：0)
您正在处理的数据看起来像JSON，但它不是 - 因为单引号（JSON需要双引号）。
假设fileContent是文件的内容（字符串，如问题所示），您可以将其转换为Python数据结构，然后搜索为字典列表：
import ast
data = ast.literal_eval(fileContent)
codes = [[field['short_name'] for field in entry['address_components']
if 'postal_code' in field['types']]
for entry in data]
#[['3006'], ['3006'], [], ['3006'], [], [], [], [], []]
您也可以从此列表中提取任何其他信息。
答案 1 :(得分：-3)
'[a-z]++_[a-z]++':'([0-9]++)'
如果中间有空格，请注意空格。
