#### S-4: Explanation
30+
When you divide one number by another you get two things. One is called the integer part of the division. Another is the remainder.
31+
32+
To get the quotient (result without the remainder), you can use two-division symbols.
33+
34+
print(37//10)
35+
36+
#### S-5: Think different
37+
Another alternative approach is to use the floor method from the math module. If you pass a number with a fraction to the math.floor function, it will return you the integer part of the number.
38+
39+
For example,
40+
```python
41+
import math
42+
result = math.floor(3.4)
43+
print(result)
44+
```
45+
**[Try It:](/https://play.google.com/store/apps/details?id=com.learnprogramming.codecamp)**
46+
47+
#### S-6: Alternative Solution
48+
Now, you can use the floor function to get the floor the division. Like below-
49+
```python
50+
import math
51+
num1 = int(input('Enter the first number: '))
52+
num2 = int(input('Enter the second number: '))
53+
54+
result = math.floor(num1//num2)
55+
print(result)
56+
```

59+
#### S-7: Quiz
60+
How will you get a floor division?
61+
62+
1. //
63+
2. /
64+
3. %
65+
66+
**The answer is: 1**
67+
68+
#### S-8: Take Away

Use // to get floor division.

## 1.5: Swap two variables

**S-1: The problem**
5+
> Swap two variables.<br><br>To swap two variables: the value of the first variable will become the value of the second variable. On the other hand, the value of the second variable will become the value of the first variable.

## S-4: Shortcut
28+
You can use a python shortcut to swap two variables as well. How this works, would be a little bit tricky for you. So, for now, just remember it.
29+
30+
```python
31+
x = 12
32+
y = 33
33+
print('x, y', x, y)
34+
#swap these two
35+
x, y = y, x
36+
print('x, y', x, y)
37+
```

**[Try It:](/https://play.google.com/store/apps/details?id=com.learnprogramming.codecamp)**
39+
40+
#### S-5: Another solution
41+
If both the variable is number, you can apply other tricks. Like the one below-
42+
43+
```python
44+
a = 5
45+
b = 7
46+
print('a, b', a, b)
47+
# swap these two
48+
a = a + b
49+
b = a - b
50+
a = a - b
51+
print('a, b', a, b)
52+
```

54+
55+
#### S-6: Quiz
56+
How would you swap two variables?
57+
58+
1. Using two temporary variables
59+
2. My family doesn’t permit swapping
60+
3. Use something like: a, b= b, a
61+
62+
**The answer is: 3**
63+
64+

## 2.3: Average of numbers
3+
4+
**S-1: The problem**
5+
Take numbers from a user and show the average of the numbers the user entered.
6+
7+
<details>
8+
<summary><b>S-2: Click Here For Show Hints</b></summary>
9+
<p>To solve this problem.
10+
11+
First, ask the user - How many numbers you want to enter?
12+
13+
Then, run a for-loop. Each time, take input from the user and put it in a list.
14+
15+
Once you get all the numbers, you can send the list to the sum function. The sum function will add all the numbers and give you the total.
16+
17+
Finally, divide the total by the number of elements the user entered.
18+
19+
That’s it, you will get the answer.

#### S-3: Solution
30+
```python
31+
len = int(input("How many numbers do you want to enter? "))
32+
33+
nums = []
34+
35+
for i in range(0, len):
36+
element = int(input("Enter element: "))
37+
nums.append(element)
38+
39+
total = sum(nums)
40+
avg = total/len
41+
print("Average of elements you entered",round(avg,2))
42+
```
43+
44+
**[Try It:](/https://play.google.com/store/apps/details?id=com.learnprogramming.codecamp)**
45+
46+
#### S-4: Explanation
47+
First, ask the user how many numbers he/she wants to enter. Once we have the number, run a for loop. To collect the numbers.
48+
49+
While collecting the numbers, we are adding those in the list called nums.
50+
51+
Then we pass the list to the sum function. The sum function returns us the sum of each number in the list
52+
53+
Eventually, we divide the total by the number of elements to get the average.
54+
55+
#### S-5: Another Solution
56+
```python
57+
len=int(input("How many numbers you want to enter: "))
58+
59+
total = 0
60+
61+
for i in range(0,len):
62+
elem=int(input("Enter element: "))
63+
total += elem
64+
65+
avg = total/len
66+
print("Average of elements you entered",round(avg,2))
67+
```
68+

69+
70+
#### S-6: Explanation
71+
In the second approach, other than directly adding to the list, we are adding it to the total variable. And then we are dividing it by the number of input the user entered.
72+
73+
#### S-7: Take Away
74+
> To get the average, calculate the total and divide by the number of elements.
