Most conditions you will use are comparisons, so it's important to discuss them in more detail. Comparisons are based on the following comparison operators:

• > (greater than);
• < (less than);
• >= (greater than or equal to);
• <= (less than or equal to);
• == (equal to);
• != (not equal to).

Moreover, you can combine multiple conditions and comparisons using the following logical operators:

• & (logical and);
• | (logical or).

If at least one of the conditions is True, then | returns True; otherwise, it returns False. If at least one of the conditions is False, then & returns False; otherwise, it returns True.

Note

Each condition should be put in parentheses () when combining them.

Don’t worry, here is an example to make everything clear:

Let's now take a look at the following visualization to understand the code better (purple squares represent the actual retrieved elements):
