Styling multi-line conditions in 'if' statements?

In Python, there are a few different ways to style multi-line conditions in if statements, depending on the complexity of the condition and personal preference.

One way is to use parentheses to group the different parts of the condition, making it easier to read:

if (condition1 and
    condition2 and
    condition3):
    # Do something

Another way is to use the backslash \ at the end of each line to indicate that the statement continues on the next line:

if condition1 and \
   condition2 and \
   condition3:
    # Do something

You can also use explicit line continuation character '' to continue the statement in the next line.

if (condition1 and \
        condition2 and \
        condition3):
    # Do something

Finally, you can also use the and operator to chain the conditions together, making it clear that they are all part of the same if statement:

if condition1 and condition2 and condition3:
    # Do something

It's important to note that, when using the backslash \ or parentheses, you should be consistent in your use of white space.

You should choose the one that you find most readable and easy to understand, and be consistent with it throughout your codebase.
