Introduction
What is an event driven programming?
These events include user input events in user interfaces, these can be resolute by events that you apply such as mouse click, messages from programs. Event driven programming is the example used in the interfaces e.g. could be JavaScript these actions have a response to the user input.

found_coins = 20 magic_coins = 10 stolen_coins = 3 print(found_coins + magic_coins * 365 - stolen_coins * 52) stolen_coins = 2 print(found_coins + magic_coins * 365 - stolen_coins * 52) magic_coins = 13 print(found_coins + magic_coins * 365 - stolen_coins * 52)

The program tells us how to multiply the numbers that are put above, e.g. found coins = 20, magic coins =10 and stolen coins=3 which are from lines 1-3 and line4 shows us a question which consists of those numbers. Line 5 shows us that stolen coins value is now 2 instead of 3 and line7 shows us that magic coins has also changed its value from 10 to 13

Event 2

spaces = ''*25
Line 2 - print('%s12 Butts Wynd' % spaces) print('%sTwinklebottom Heath' % spaces) print('%sWest Snoring' % spaces) print() print() print('Dear Sir') print() print('I wish to report that tiles are missing from the') print('outside toilet roof.') print('I think it was bad wind the other night that blew away.') print() print('Regards') print('Malcolm Dithering')

Line 15 - 12 Butts Wynd
Twinklebottom Heath
West Snoring
()
()
Dear Sir
()
I wish to report that tiles are missing from the outside toilet roof.
I think it was bad wind the other night that blew away.
()
Regards
Malcolm Dithering

The above program tells us that when you add a % in front of a word or sentence that you input it adds spaces in-between as you can see from line 2 and its completed version in line 15. Also when you add () it just prints the same exact thing like it has breaks in the sentence to inform you that you have moved the text under another text.

Event 3

favorite_sports = {'Ralph Williams':'Football', 'Michael Tippett':'Basketball','Edward Elgar':
Line 2 - 'Baseball','Rebecca Clarke':'Netball','Ethel Smyth':'Badminton','Frank Bridge':'Rugby'}
Line 3 - print(favorite_sports['Rebecca Clarke'])
Line 4 - del favorite_sports['Ethel Smyth'] print(favorite_sports) favorite_sports['Ralph Williams']='Ice Hockey' print(favorite_sports) Line 8 - Netball
{'Ralph Williams': 'Football', 'Michael Tippett': 'Basketball', 'Edward Elgar': 'Baseball', 'Rebecca Clarke': 'Netball', 'Frank Bridge': 'Rugby'}
{'Ralph Williams': 'Ice Hockey', 'Michael Tippett': 'Basketball', 'Edward Elgar': 'Baseball', 'Rebecca Clarke': 'Netball', 'Frank Bridge': 'Rugby'}

The program above tell us that the favourite sports for each person e.g. 'Ralph Williams':'Football', 'Michael Tippett':'Basketball','Edward Elgar': 'Baseball','Rebecca Clarke':'Netball','Ethel Smyth':'Badminton','Frank Bridge':'Rugby'. The program also tells us that it print Rebecca Clarkes favourite sport and delete Ethel Symths favourite sport and this can be shown in Line 2, Line 3 and Line 4 and it can be shown that it’s been added and deleted in Line 8 and the following lines after that.

Event 4

furniture='%s: a device for finding furniture in the dark' bodypart1 = 'Knee' bodypart2 = 'Shin' print(furniture%bodypart1) print(furniture%bodypart2)

Knee: a device for finding furniture in the dark
Shin: a device for finding furniture in the dark
The above program tells us that furniture = a device for finding furniture in the dark' and there are to parts to this and they are for body part 1 and body part 2 when you print both of them separately obviously e.g. of a print can be print (furniture%bodypart1)’ and he answer you get is Knee: a device for finding furniture in the dark.

Event 5

single_quote_str='He said, "Aren\'t can\'t shouldn\'t wouldn\'t."' print(single_quote_str) double_quote_str="he said, \"Aren't can't shouldn't wouldn't.\"" print(double_quote_str) Line 5 - He said, "Aren't can't shouldn't wouldn't."
Line 6 - He said, "Aren't can't shouldn't wouldn't."

The above program tells us that when you add a single quote where the wording is integrated by slashes and when you also print the same thing but without slashes in tem the answer you still get is the same as you can see in lines 5 and 6.

Event 6

wizard_list=['spider legs','toe of frog','eye of newt','bat wing','slug butter','snake dandruff'] print(wizard_list) wizard_list[2]='snail tongue' print(wizard_list) print(wizard_list[2:5])
Line 6 - wizard_list.append('bear burp') print(wizard_list) Line 8 - wizard_list.append('mandrake')
Line 9 - wizard_list.append('hemlock')
Line 10 - wizard_list.append('swamp gas') print(wizard_list) del wizard_list[5] print(wizard_list) del wizard_list[8] del wizard_list[7] del wizard_list[6] print(wizard_list) ['spider legs', 'toe of frog', 'eye of newt', 'bat wing', 'slug butter', 'snake dandruff']
['spider legs', 'toe of frog', 'snail tongue', 'bat wing', 'slug butter', 'snake dandruff']
['snail tongue', 'bat wing', 'slug butter']
['spider legs', 'toe of frog', 'snail tongue', 'bat wing', 'slug butter', 'snake dandruff', 'bear burp']
['spider legs', 'toe of frog', 'snail tongue', 'bat wing', 'slug butter', 'snake dandruff', 'bear burp', 'mandrake', 'hemlock', 'swamp gas']
['spider legs', 'toe of frog', 'snail tongue', 'bat wing', 'slug butter', 'bear burp', 'mandrake', 'hemlock', 'swamp gas']
['spider legs', 'toe of frog', 'snail tongue', 'bat wing', 'slug butter', 'bear burp']

The above program tells us that there is a wizard list and it consists of =['spider legs','toe of frog','eye of newt','bat wing','slug butter','snake dandruff'] which is in line 1 and that in line there is a change of substance because instead of it being ‘eye of newt’ its changed to ‘snail tongue’ and from then on the wizard list has changed and also in lines 6,8,9 and 10 the words , 'bear burp', 'mandrake', 'hemlock', 'swamp gas’ are added to the wizard list and as we get towards the end it tells us to delete wizard lists 8,7 and 6 and the last line in the whole code doesn’t include , 'mandrake', 'hemlock', 'swamp gas'.

Event 7

Line 1 - numbers=[1,2,3,4]
Line 2 - strings=['I','kicked','my','toe','and','it','is','sore'] mylist=[numbers,strings] Line 4 - print(mylist)

[[1, 2, 3, 4], ['I', 'kicked', 'my', 'toe', 'and', 'it', 'is', 'sore']]

The above program tells us that there are number which include 1,2,3 and 4 which you can see in line 1 and the strings in line 2 and they are both put together to form a sentence which can be shown in line 4 of the code.
