我是 python 的新手,我在 regex 和 csv 写作方面遇到了问题。
这是代码
import re
import csv
match_text = re.compile(r'[^(<a href="/employer/\d+?\>)].+[^(\s</a>)]', re.UNICODE)
match_hh_company_url = re.compile(r'/employer/\d+', re.UNICODE)
def listing_employers():
...
## making a list with some data
...
source_list = match_page.findall(data)
source_list = set(source_list)
return source_list
def w_to_file(f_name, source_list):
with open(f_name, 'wb') as csvfile:
bankwriter = csv.writer(csvfile, dialect='excel')
for each in source_list:
bankwriter.writerow(match_text.findall(each) + match_hh_company_url(each))
w_to_file('bank_base', listing_employers())
一切都很好,但是连接存在问题match_text.findall(each) + match_hh_company_url(each)
- 它会引发错误:
Traceback (most recent call last):
File "salebase.py", line 41, in <module>
w_to_file('bank_base', listing_employers())
File "salebase.py", line 33, in w_to_file
bankwriter.writerow(match_text.findall(each) + match_hh_company_url(each))
TypeError: '_sre.SRE_Pattern' object is not callable
没关系,如果我只使用一个match_
,但不能与 一起使用+
,那很奇怪。我试图在 shell 中模拟情况,它有效!!:
>>> import re
>>> m = re.compile('\d{3}')
>>> n = re. compile('[a-z]')
>>> a = ['111 a', 'a333', 'f444b']
>>> for x in a:
... print m.findall(x)
...
['111']
['333']
['444']
>>> for x in a:
... print m.findall(x) + n.findall(x)
...
['111', 'a']
['333', 'a']
['444', 'f', 'b']
>>>
如果这很重要,我会source_list
通过将表达式与文本块匹配并将其放在列表中。这就是listed_employers() 函数的含义。完整代码在这里: http: //pastebin.com/bimhfAtn
那么谁能帮帮我,有什么问题吗?
