当用户输入电子邮件地址时，程序读取电子邮件并根据其标准(例如 yeo.myy@edu.co)显示它，例如标准:
用户名是yeo.myy域是edu.co
我知道它与 "@" 有关。
这是代码
class Email:
def __int__(self,emailAddr):
self.emailAddr = emailAddr
def domain(self):
index = 0
for i in range(len(emailAddr)):
if emailAddr[i] == "@":
index = i
return self.emailAddr[index+1:]
def username(self):
index = 0
for i in range(len(emailAddr)):
if emailAddr[i] == "@" :
index = i
return self.emailAddr[:index]
def main():
emailAddr = raw_input("Enter your email>>")
user = Email(emailAddr)
print "Username = ", user.username()
print "Domain = ", user.domain()
main()
这是我得到的错误:
Traceback (most recent call last):
File "C:/Users/Owner/Desktop/sdsd", line 29, in <module>
main()
File "C:/Users/Owner/Desktop/sdsd", line 24, in main
user = Email(emailAddr)
TypeError: this constructor takes no arguments
请您参考如下方法:
def __int__(self,emailAddr):
你是说 __init__ 吗？
def __init__(self,emailAddr):
您的方法中还缺少几个 self，并且您的 return 缩进不正确。
def domain(self):
index = 0
for i in range(len(self.emailAddr)):
if self.emailAddr[i] == "@":
index = i
return self.emailAddr[index+1:]
def username(self):
index = 0
for i in range(len(self.emailAddr)):
if self.emailAddr[i] == "@" :
index = i
return self.emailAddr[:index]
结果:
Username = yeo.myy
Domain = edu.co
顺便推荐partition和 rpartition用于在给定的分隔符上将字符串分成两部分。当然胜过手动跟踪索引。
def domain(self):
return self.emailAddr.rpartition("@")[2]
def username(self):
return self.emailAddr.rpartition("@")[0]
