How to Split Long Strings in Python

In programming, it is often necessary to split long strings over multiple lines for readability. While JavaScript offers a simple solution using the operator, Python requires a different approach.

To split a string in Python, you can use either triple quotes (''' or """) or parentheses (()). Triple quotes allow you to include newlines and spaces within the string, as seen in the following example:

s = ''' this is a very
        long string if I had the
        energy to type more and more ...'''

Parentheses, on the other hand, create a string without any extra spaces or newlines, as shown below:

s = ("this is a very"
      "long string too"
      "for sure ..."
     )

The choice of method depends on your specific needs. Triple quotes are best for strings containing newlines and spaces, while parentheses are preferred for strings that require more flexibility in combining multiple lines.

In the provided example, the query string can be split using triple quotes, as it contains both newlines and spaces:

query = '''
SELECT action.descr as "action",
role.id as role_id,
role.descr as role
FROM
public.role_action_def,
public.role,
public.record_def,
public.action
WHERE role.id = role_action_def.role_id AND
record_def.id = role_action_def.def_id AND
action.id = role_action_def.action_id AND
role_action_def.account_id = ' + account_id + ' AND
record_def.account_id=' + account_id + ' AND
def_id=' + def_id + '''

This approach ensures readability and eliminates the need for awkward sequences to split the string.
