Answer 2

b = 5 # Sets Value of b to Integer 5
list=“” # Creates an emty String
while b < 11: # This Loop will continue as long as the value b is smaller than 11
b = b + 2 # Adds 2 to b. With the first Iteration b is 7
if b % 2 == 1 # Checks if b is an odd Number
list = str(b) + ” “ + list # Adds the current Value of b to the List if the Condition of the if-Statement is True
print (list) # Output of the final List
----
By the Way this Program makes not much sence. It starts with an odd number and adds 2 - it is logical that this must be an odd Number, too.

Answer 3

Because you add str(b) + list. If you want an ascending Order write
list = list + " " + str(b)

Answer 4

You can do it with a list comprehension
print([b for b in range(7, 13, 2) if b%2])

Answer 5

Python will execute your Code exactly in the Order you write it down:
list = list + str(b)
means that 'b' will be appended to the existing 'list'. The result is a 'list' in ascending Order.
list = str(b) + list
means that the existing 'list' will be appended to 'b'. The Result is a List in descending Order.

Answer 6

list is the Name of the Stirng you defined in Line 2.

Answer 7

You should define a List like that:
list = []
and add Items with
list.append()

Answer 11

@Sebastian KeBler
Thank you so much. But I’m confused about how it’s 11 9 7 and not 7 9 11. Why is it in reverse?

Answer 12

So does it mean that “list” is nothing?

Answer 13

What is list? I don’t know the value for list.
