How to add line breaks to prevent overly long lines?

Question

I just read the best practices of Python scripts. I found recommended length should not exceed 80 characters per line.

So in my script more than 100 characters are exist.

I have break the lines and below are examples.

• Example 1

  self.remote_conn_pre.connect("self.hostname, "
      "username=self.username, password=self.password, "
       "look_for_keys=False, allow_agent=False")
  

• Example 2

   self.remote_conn.send(""create bigdata\n" "
      " .format(pending.upper(), (total) + 9)")
  

• Example 3

   print ("This is the first line of my text {} "
   "which will be joined to a second {}.".format(a,b))
  

Could any one please correct me if I am doing anything wrong and help me determine the best ways to break long lines into small lines.

Answer 1

Python supports splitting up lines using the backslash \ character, like so:

d = "one two three " \
    "four five six"

print d

Prints one two three four five six

Answer 2

You can use docstrings and escape the newline character.

print ("""
This is the first line of my text {} \
which will be joined to a second {}.
""").format(a,b)
