During week 1 you have played a text based game and had a look at the Python code.
During week 2, you have learned and practiced using while loops.
For this assignment
1. Write lines of code for the following:
  1. ask user to input a number and store the input in a variable
  2. convert the input number to an integer
  3. if the number is greater or equal to 10, output "It's double digit number at least", else output "It's a small number"
2. Explain how this line of code works:
```
random.randrange(0,10)
```
3. The follow code is supposed to output numbers from 0 to 9. But it has an error in it. Please identify the error.

while x < 10:
	x = 0
	print (x)
	x += 1

1 2	for I in range(5): print("Welcome to the range")

The above code is a for loop - that is, the command indented underneath the for i in range(5) will be repeated. In this case, the Welcome to the range will be printed 5 times. Why?
It is becasue the number of times a loop repeats is specified by the number given in the range(5).
Range command works like this:
1. range(upToNumber) - it produce a sequence of numbers from 0 up to BUT NOT equal to the upToNumber. For example, range(5) will produce: 0,1,2,3,4, therefore, there are 5 numbers, for each number the loop going through, it prints out "Welcome to the range".
2. range(startNumber, upToNumber) - it produces a sequence of numbers from startNumber to BUT NOT equal to the upToNumber. For example, range(3,8) will produce: 3,4,5,6,7
3. range(startNumber, upToNumber, increaseBy)- it produces a sequence of numbers from startNumber to BUT NOT equal to the upToNumber, each time the next number increase by the number specified by increaseBy. For example, range(2,10,2) will produce: 2,4,6,8.
Your homework:
1. What numbers are produced in this loop:
  1 2
  for i in range(10, 20, 2): print(i)
2. What numbers are produced in this loop:
  1 2
  for i in range(100, 40, -5): print(i)
3. write a for loop that will print out all positive whole numbers (integers) up to 100 that are divisible by 5.
