Python中的字符串操作

我试图写一个命令，但我不希望一个长的行，看起来不整洁。我希望将字符串添加到一起，以便按命令执行。我在下面有一些代码，这是电子邮件功能的一部分：

msg = MIMEText("The nightly build status was a SUCCESS\n\nBuild File: http://www.python.org\n\n Build Results File: http://10.51.54.57/sandboxes/", project, "\n")

这显示了一条线，我希望有更好的方法来做到这一点。我已经尝试了下面的代码，但它不工作

msg = MIMEText("The nightly build status was a SUCCESS\n\nBuild File: ")
msg += MIMEText("http://www.python.org\n\n Build Results File: ")
msg += MIMEText("http://10.51.54.57/sandboxes/", project, "\n")

谢谢你的帮助

我尝试了以下代码，但得到：

msg = MIMEText("""The nightly build status was a SUCCESS\n\n
   Build File: """,  
   build_file, """
   \n\n 
   Build Results File: """, 
   build_file, """
   \n\n
   Sandbox Folder:""", 
   sandbox, """ 
   \n\n
   Antibrick File: """,
   antibrick, "\n\n")

现在我明白了：

Traceback (most recent call last):
  File "test_email.py", line 45, in <module>
    if __name__ == '__main__': myObject = email_success()
  File "test_email.py", line 32, in email_success
    antibrick, "\n\n")
TypeError: __init__() takes at most 4 arguments (10 given)

尝试：

如果每行开头的额外空格有问题，请使用regexp（

r'^\s+'

）删除它们。

您可以使用三重引号

>>> s="""The nightly build status was a SUCCESS

Build File: http://www.python.org

Build Results File: http://10.51.54.57/sandboxes/"""

>>> msg=MimeType(s,project,"\n")

怎么样

msg = MIMEText(
"The nightly build status was a SUCCESS\n\n"
"Build File: http://www.python.org\n\n"
"Build Results File: http://10.51.54.57/sandboxes/"
, project
, "\n"
)

或

或

更新：因为OP添加了另一个问题

msg=MIMEText("""The nightly build status was a SUCCESS\n\n
    Build File: %s
    \n\n 
    Build Results File: %s
    \n\n
    Sandbox Folder: %s 
    \n\n
    Antibrick File: """ % (build_file,build_file,sandbox),
    antibrick, 
    "\n\n"
)

Python支持使用三重引号的多行字符串：

text = """The nightly build status was a SUCCESS\n\nBuild File: 
http://www.python.org\n\n Build Results File: 
http://10.51.54.57/sandboxes/"""
msg = MIMEText(text, project, "\n")

为什么不呢

msg= MIMEText("The nightly build status was a SUCCESS\n\nBuild File: "+ \
  "http://www.python.org\n\n Bu..... ") 

等等

（即，使用直线延续反斜杠）

还要注意的是，以下每一项都给出了abcdef

而且

 s="""xyz
    wvu"""

给你

'xyz\nwvu'

嗯，你使用的模块是什么？我猜，这是不推荐的，因为现代界面是（如果我猜对了你的意图的话）。更具体地说，创建您使用的

MIMEText

对象。签名是

email.mime.text.MIMEText(_text[, _subtype[, _charset]])

---

请指定您遇到的错误。可能无法像那样将

MIMEText

连接在一起。错误说明了一切！！您有10个参数传递给MIMEText。正确构建您的消息。

msg= MIMEText("The nightly build status was a SUCCESS\n\nBuild File: "+ \
  "http://www.python.org\n\n Bu..... ") 

s ="abc" "def"

s= "abc" \
     "def"

 s="""xyz
    wvu"""

'xyz\nwvu'

email.mime.text.MIMEText(_text[, _subtype[, _charset]])
