Let's move on to more complex conditions that combine several simple conditions. 

1. **and** - condition_1 and condition_2 -- works only if both `condition_1` and `condition_2` are true.
2. **or** - condition_1 or condition_2 -- works if **at least one** of the two specified conditions: `condition_1`, `condition_2` is true (or both at the same time).
3. **not** -- not `condition` it applies to one condition (not two as above) and inverts its value, works if the `condition` is false.

Look at the next examples.
Let's imagine that you passed exams in three subjects, and got the following result: `math_exam = 95`, `english_exam = 90`, `programming_exam = 100`.
And you have decided to submit your application to study at three different universities. And all these three universities have different conditions for admission. Let's look at them.

In order to enter the first university, you must have greater than or equal to 90 from all three subjects at the same time. Let's see if you can get into this university


```
Input:
# Your scores
math_exam = 95
english_exam = 90
programming_exam = 100

# Checking whether you will pass to the first university
if math_exam >= 90 and english_exam >= 90 and programming_exam >= 90:
    print('Congratulations! You are enrolled in our university')
Output:
Congratulations! You are enrolled in our university
```

As we can see, your scores from all exams are greater than or equal to 90, so our **if** statement worked.

Then move on to the next university. Here the condition is different, since this is the best university in your city, your scores must be greater than or equal to 95.


```
Input:
# Your scores
math_exam = 95
english_exam = 90
programming_exam = 100

# Checking whether you will pass to the second university
if math_exam >= 95 and english_exam >= 95 and programming_exam >= 95:
    print('Congratulations! You are enrolled in our university')
Output:

```

As we see that our condition is not fulfilled, since we have two objects that satisfy the condition, but the third object, namely `english_exam = 90`, it is less than 95. Therefore, we do not get anything as a result, and our **if** statement is not executed.

Moving on to the next university. Here the condition is quite simple. In order to pass here, you need to have **at least one** subject that has passed **100 points**.

It is obvious that for this case we need to use the **or** operator.


```
Input:
# Your scores
math_exam = 95
english_exam = 90
programming_exam = 100

# Checking whether you will pass to the third university
if math_exam == 100 or english_exam == 100 or programming_exam == 100:
    print('Congratulations! You are enrolled in our university')
Output:
Congratulations! You are enrolled in our university
```

As we can see that we still have one subject that was passed for 100 points. As we understand, for the operator **or** it is enough that one condition is **True**.

It is worth remembering that if not a single condition was **True**, then we would not get anything as a result, since the **if** statement would not work.

It's time to practice!

Here we get acquainted with the simplest representations of the conditional operator if. In addition, we get acquainted with the use of logical operators and the priorities for their use, after which we consolidate the knowledge of practice.

In this section, we are introduced to a more advanced form of the conditional operator - if-else. We will also learn what nested if-else statements are and practice on tasks.

At the end of the course, we will learn about the most advanced form of the conditional operator if-elif-else, get acquainted with the syntax of this construction and how it is applied correctly.
