TB1 Week 6

This week, completed a quiz on what I’ve learnt so far about python.

https://moodle.port.ac.uk/pluginfile.php/3804620/mod_resource/content/5/MoreQ.pdf 

Q1: c (Because things like easier to read and more modular scripts are good, especially if they are compliant with client requirements, however self explanatory is not a good reason as the code should be clearly written and commented rather than assumed to be legible)

The answer is d

Q2: d (Because a function has to be called to return the value it has, it needs to use the return keyword to do so)

Q3: d (Because there is one too many closed brackets when y is being defined, returning a syntax error)

Answer actually isn’t there and it isn’t a syntax error it will just go through the function then return it again making 9*9, making the answer 3,81

Q4: b (As you need to order variables by making them equal something to their right, and the brackets will make sure the values are stored for u and v both?)

A and b are both correct

Q5: a (items are added to dictionaries by using dictname[“item”] = “itemname”)

Cannot use curly brackets for dictionary functions

Q6: d (This will check if x is less than y and the colon at the end is used to show the end of that line)

Q7: d (loop prints out only i then prints out the target which has been combined with the max i value)

Q8: a (As append does not remove items from a list, and because there are no syntax errors)

Q9: b (As there is no syntax error and the if statement is not true as y does not equal and is not greater than 30)

Q10: d (You can not mix integer and string values)

Q11: b (You use the #)

Q12: b (Using bidmas in the brackets before multiplying by 2)

Q13: d (Using bidmas again)

Q14: a (As it would become 14 while going through ex2 then be divided by 2 and returned)

Q15: c (As it would not be greater than 20 by the time it would have 2 added to it and printed making it 21, once it checks again whether or not a is greater than 20 it would fail breaking the loop)

It’s b, pay closer attention to the order of the print and the loop

Q16: c (Comments do not do anything to the actual code of the script)

Q17: d (It’s how it works)

Q18: c (it is going to the nested list and then using the 3rd element inside of it which is 8/4 which is 2)

Q19: b (break stops loops)

Q20: b (bidmas)
