How to wrap code in python

How to wrap code in python: 1. Add the line continuation character "\" (i.e. space\) at the end of the code that needs to be wrapped; 2. Add brackets, "()", "{} There is no need to add newline characters in "[]". Python will implicitly connect the lines in parentheses, square brackets and curly brackets.

Python recommends that the length of each line of code should not exceed 80 characters . For codes that are too long, it is recommended to wrap the code.

1. Add the line continuation character "\" (space\) at the end of the line of code:

test = 'item_one' \
'item_two' \
  'tem_three'

Output result: 'item_oneitem_twotem_three'

2. Add parentheses, () {} [] do not need to add special line breaks:

We can use Python to add the characters in parentheses, square brackets and curly brackets This feature of implicitly connecting lines changes the display of overly long statements and adds a pair of parentheses outside the statements.

test2 = ('csdn '
'cssdn')

Output result: csdn cssdn

test3 =('Hello'
' '
'world')

Need to pay attention What's more, when statements in [], {} or () are wrapped, we no longer need to use parentheses for wrapping. The sample code is as follows:

total = ['item one', 'item two', 'item three'，
         'item four', item_five']
