Problem

There is a string that is very long. How to write it in multiple lines?

Solve

Method 1

Use a continuation character:

sql = "select * "\
" from a "\
" where b = 1"

However, the higher version of python may not support this method, and it is not concise to add a continuation character at the end of the line every time.

Method 2

Use parentheses:

sql = ("select *"
" from a "
" where b = 1")

Strings in parentheses can be written in multiple lines. It is recommended.
