Explanation / Answer

1. 7//2 would give the output of integer division of 7 and 2. that is 3
2. Boolean literals in python are True and False

3. var = (num>=0 and num<=10)

4. While loop stops when the condition specified in the while is not satisfied

5. range() function creates a list of numbers to loop through using for loop

6. range(5) will produce the list [0,1,2,3,4]

7. range(1,5) will give the list [1,2,3,4]

8. range(1,10,2) will give the list [1,3,5,7,9]

9. Argument specify the uppper bound (Exclusive) for the list, where as the lower bound is 0

10. *= is the operator. num*=10 will multiply num by 10 and store the result in the num

11. def max(a,b)

12. Variable defined inside a function in python is known as local variable, Unless it is explicitly declared using 'global' keyword, which makes in global. A local variable can be accessed from the function only.

13. When a variable is defined inside a function, no code outside the function can use that variable unless the variable is defined using the keyword global, which makes it global variable

14. Variables defined outside a function are known as global variables

15. parameters of a function get values , when we invoke them.
Whenever we invoke a function eg. sum(list), the passed value is assigned to the parameter and used in the method
