The Magic Square is a grid with 3 rows and 3 columns with the following properties: • The grid contains every number from 1 to 9

. • The sum of each row, each column, and each diagonal all add up to the same number. This is an example of a Magic Square: 4 9 2 3 5 7 8 1 6 You can simulate a 3x3 grid using a two-dimensional list. For example, the list corresponding to the grid above would be: [[4, 9, 2], [3, 5, 7], [8, 1, 6]] Write a function that accepts a two-dimensional list as an argument and returns whether the list represents a Magic Square (either True or False). Create a program that tests the function on the following two-dimensional lists and prints out the results each on a separate line: [[4, 9, 2], [3, 5, 7], [8, 1, 6]] [[2, 7, 6], [9, 5, 1], [4, 3, 8]] [[1, 2, 3], [4, 5, 6], [7, 8, 9]] [[4, 9, 2], [3, 5, 5], [8, 1, 6]]

Answer:

Will have to run the net start spooler command.

Explanation:

  • The printer spooler seems to be accountable for overseeing incoming faxes that have been in effect intended for handling by the printer. Whether this device stops operating, your printer won't publish documentation as well as the machine may not notice it either.
  • To solve these problems, you'll need to run the net start spooler command using the least administrative effort.

A new laptop was delivered to your home and left on the porch while you were at work. It is very cold outside, and you don't kno
kifflom [539]

Answer:

Let the computer warm up to room temperature before turning it on.

Explanation:

The laptop has been shipped to the user's home when he were at work and found on the deck. Outside it is really cool and he don't remember how long it has been there. Then, the user open his laptop and want to know whether it is functioning properly. Instead, let the machine warm up while switching it on to room temperature.

When a computer is still in a cold climate, they have to let it heat up to room temperature apx. 6-24 hours before switching it on. Otherwise, its heat the elements generate could cause water moisture within the laptop. That water could then harm elements of the system.

Pick the 3 correct Python functions that parse and output only the date and time part of each log in log.txt as follows.
Mila [183]

Answer:

1, 4, 5

Explanation:

parse2:

. In this case it's passing "r" as an argument, which really does absolutely nothing, because whenever you call open("file.txt") it defaults to reading mode, so all you're doing is explicitly passing the "r". So let's look at the first line. Whenever you call str.split() without any arguments, by default it splits it by empty text, and filters any empty text. So str.split() is not the same as str.split(" ") although it has similar behavior. "     ".split(" ") will output ['', '', '', '', '', ''], while "     ".split() will output []. So in this case the line.split() will split the string '10.1.2.1 - car [01/Mar/2022:13:05:05  +0900] "GET /python HTTP/1.0" 200 2222' into the list<em> ['10.1.2.1', '-', 'car', '[01/Mar/2022:13:05:05', '+0900]', '"GET', '/python', 'HTTP/1.0"', '200', '2222'].</em> As you can see the the data is split into two pieces of text, AND they include the brackets in both strings. So when it gets the 3 index and strips it of the "[]" it will have the incomplete date

parse3:

 In this instance the "r" does nothing as mentioned before the "r" is already defaulted whenever you call open("file.txt") so open("file.txt") is the same as open("file.txt", "r"). So in this case we won't be working left to right, we're going inside the brackets first, kind of like in math you don't don't work left to right in equation 3 + 3(2+3). You work in the brackets first (inside brackets you do left to right). So the first piece of code to run is the line.split("[" or "]"). I actually kind of misspoke here. Technically the "[" or "]" runs first because this doesn't do what you may think it does. The or will only return one value. this is not splitting the line by both "[" and "]". The, or will evaluate which is true from left to right, and if it is true, it returns that. Since strings are evaluated on their length to determine if they're true. the "[" will evaluate to true, because any string that is not empty is true, if a string is empty it's false. So the "[" will evaluate to true this the "[" or "]" will evaluate to "[". So after that the code will run line.split("[") which makes the list: <em>['10.1.2.1 - car ', '01/Mar/2022:13:05:05  +0900] "GET /python HTTP/1.0" 200 2222']</em>. Now the [3:5] will splice the list so that it returns a list with the elements at index 3 (including 3) to 5 (excluding 5). This returns the list: [], because the previous list only has 2 elements. There are no elements at index 3 to 5 (excluding 5). So when you join the list by " ", you'll get an empty string

parse4:

  So I'm actually a bit confused here, I thought the "r+" would open the file in read-writing mode, but maybe this is a different version of python I have no idea, so I'm going to assume it is reading/writing mode, which just means you can read and write to the file. Anyways when you split the line by doing line.split(), as mentioned before it will split by empty spaces and filter any empty spaces. This line will return: <em>['10.1.2.1', '-', 'car', '[01/Mar/2022:13:05:05', '+0900]', '"GET', '/python', 'HTTP/1.0"', '200', '2222']</em>. and then you splice the list from indexes 3 to 5 (excluding 5). This will return the list: <em>['[01/Mar/2022:13:05:05', '+0900]']</em> which has the two pieces of information you need for the date. Now it joins them by a space which will output: '[01/Mar/2022:13:05:05 +0900]'. Now when you strip the "[]" you get the string: '01/Mar/2022:13:05:05 +0900' which is the correct output!

parse 5:

 So in this example it's using re.split. And the re.split is splitting by "[" or "]" which is what re.split can be used for, to split by multiple strings, which may be confused by string.split("[" or "]") which is not the same thing as explained above what the latter does. Also the reason there is a backslash in front of the [ and ] is to escape it, because normally those two characters would be used to define a set, but by using a \ in front of it, you're essentially telling regex to interpret it literally. So in splitting the string by "[" and "]" you'll get the list: <em>['10.1.2.1 - car ', '01/Mar/2022:13:05:05  +0900', ' "GET /python HTTP/1.0" 200 2222']</em> which has 3 elements, since it was split by the [ and the ]. The second element has the date, so all you need to do is index the list using the index 1, which is exactly what the code does
