``` #declare two set the range
1.i = 1
2.j = 5
#use while loop for i
3.while i < 4:
#use while loop for j
4.while j < 8:
5.print(i, ",", j)
6.j = j + 1
7.i = i + 1
Output:
1 , 5
2 , 6
3 , 7
```
```days = 0
week = [‘Monday’, ‘Tuesday’, ‘Wednesday’, ‘Thursday’, ‘Friday’, ‘Saturday’, 3.‘Sunday’]
while day < 7:
print(“Today is” + week[days])
days += 1

```
```# Program to add natural
# numbers upto
# sum = 1+2+3+...+n

# To take input from the user,
# n = int(input("Enter n: "))

1.n = 10

# initialize sum and counter
2.sum = 0
3.i = 1

4.while i <= n:
5. sum = sum + i
6. i = i+1    # update counter

# print the sum
7.print("The sum is", sum)

When you run this code output will be:
Enter n: 10
The sum is 55
