正则表达式 python 匹配不同国家的不同邮政编码

如何解决正则表达式 python 匹配不同国家的不同邮政编码

我有一个关于 python 正则表达式的问题。 我正在尝试使用flask-restful制作一个注册页面，并且我正在努力将邮政编码匹配到不同的国家。例如邮政编码荷兰：1234AB，邮政编码比利时：1234。 我想要的是：如果荷兰是选择的国家，邮政编码必须有 4 位数字和 2 个字符。 如果选择的国家是比利时，则邮政编码必须只有 4 位数字。

con = sqlite3.connect("db/webshop.db")
        cur = con.cursor()
        split_string = args['email'].split("@",1)
        substring = split_string[0]
        if len(args['password']) < 8:
            print("Make sure your password is at least 8 letters")
            return
        elif re.search('[0-9]',args['password']) is None:
            print("Make sure your password has a number in it")
            return
        elif re.search('[A-Z]',args['password']) is None: 
            print("Make sure your password has a capital letter in it")
            return
        elif len(substring) <= 5:
            print("Make sure your email has 5 letter in it")
            return
        elif args['email'].find('@')==-1:
            print("Make sure your email has @ letter in it")
            return
        elif args['email'].find('.')==-1:
            print("Make sure your email has . letter in it")
            return
        elif args['country'] == '1':
            if re.match(r'\d[0-9]{4}',args['zipcode']):
                cur.execute("INSERT INTO users (email,password,firstname,infix,lastname,street,housenumber,zipcode,city,newsletter,userrole_id,country_id) VALUES (?,?,?)",(args['email'],args['password'],args['firstname'],args['infix'],args['lastname'],args['street'],args['housenumber'],args['zipcode'],args['city'],args['newsletter'],'1',args['country']))
                con.commit()
            else:
                print("zipcode is not matching with given arguments")
                return

解决方法

您可以尝试以下操作：

belgium = '1' # assuming that belgium is '1'

if args['country'] == belgium:
  zip_code_regexp = "^[0-9]{4}$"
else:
  zip_code_regexp = "^[0-9]{4}[A-Z]{2}$"


if re.match(zip_code_regexp,args['zipcode']):
  # ...
else:
  # ...
