Lesson Contents
One of the Python operator types are Python logical operators. We can combine conditional statements.
In the Python comparison operators lesson, we used operators to check if the result is true or false. For example:
The first operator returns true, the second one returns false. What if I want to check both conditions? That’s what we can do with logical operators:
- AND
- OR
- NOT
Let’s try these.
AND
The AND operator returns true when both conditions are true. Otherwise, it returns false.
| X | Y | Result |
| False | False | False |
| False | True | False |
| True | False | False |
| True | True | True |
Here’s an example:
Both conditions are true, so the operator returns true. One more example:
The second condition is false, so the operator returns false as the result. In the two examples above I used numbers but you can also check other items. Here’s an example:
The string “switch” equals “switch” and 10 is greater than 5, so the operator returns “true”.
OR
The OR operator returns true if at least one of the conditions is true.
| X | Y | Result |
| False | False | False |
| False | True | True |
| True | False | True |
| True | True | True |
Here’s an example:
Both conditions are true, so the operator returns true. One more example:
