ALTER TABLE user ADD CONSTRAINT user_number_unique UNIQUE (user_number); 

Common mistakes with adding the UNIQUE constraint to an existing column include not having ( ) around the column names, omitting the keyword UNIQUE, incorrectly spelling the column name, and not including the constraint name.

Debugging a code involves locating the errors in a code segment, and fixing them.

When the program was run on GDB, the program give the following error

Main.java:62: error: reached end of file while parsing

This means that we need to add a closing brace to the end of the program.

A second run after fixing this error gives another set of errors:

Main.java:4: error: class Contribution is public, should be declared in a file named Contribution.java

It should be noted that GDB only allows you to create a program with the file name Main i.e. Main.java

This means that we change the Contribution keywords in the program to Main.

After this has been done, the program gives the following output:

It took 17 contributions to reach the goal.

The maximum contribution received was $189.0.

The minimum contribution received was $3.0

The average contribution amount was $60.0.

A total of $1012.0 was collected.

Explanation:

Method 1 :

Using If else statements: If the condition checks whether num1 is smaller than num2 if so it will print 'Smallest of these two integers is num1'.

else it will print 'Smallest of these two integers is num2'

Method 2:

Using the 'min' method: using the method min(num1,num2), the program finds the smallest value and prints it directly to the user.

Python Program using method 1

#PYTHON PROGRAM TO FIND SMALLEST INTEGER VALUE FROM TWO INPUTS FROM USER - Method 1

#Accepts inputs from user

num1 = int (input ("Enter your first number:")) #Gets the first integer input from user and stores in num1

num2 = int (input ("Enter your second number: ")) #Gets the second integer input from user and stores in num2

#Finding output by if else

#Checks num1 smaller than num2

if (num1 < num2):

#assign num1 to small

small = num1

else:

#assign num2 to small

small = num2

print ("Smallest of these two integers is", small)

Python Program using method 2

#PYTHON PROGRAM TO FIND SMALLEST INTEGER VALUE FROM TWO INPUTS FROM USER - Method 2

#Accepts inputs from user

Answer:num1 = int(input())

An important factor between qubits and normal bits is that a lot of qubits can show quantum entanglement.

ansList = [int(i) for i in ansList if int(i)>0] #turn string to integer,and get all positive integers

print(ansList)

Explanation: I think this would work for you. I leace comments in the answer.

The program that reads a list of integers into a list as long as the integers are greater than zero is coded in the source code.

Source code:

user_numbers = []

user_input = int(input("Enter an integer (enter a non-positive integer to stop): "))

while user_input > 0:

   user_numbers.append(user_input)

   user_input = int(input("Enter an integer (enter a non-positive integer to stop): "))

print(user_numbers)

In this program, we initialize an empty list user_numbers to store the integers entered by the user. We then use a while loop to repeatedly prompt the user to enter an integer.

If the entered integer is greater than 0, it is appended to the user_numbers list. If the entered integer is non-positive (less than or equal to 0), the loop terminates.

You might need to click Browse or Computer, and navigate to the location for your new folder. In the Save As dialog box that opens, click New Folder.

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 ['10.1.2.1', '-', 'car', '[01/Mar/2022:13:05:05', '+0900]', '"GET', '/python', 'HTTP/1.0"', '200', '2222']. 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: ['10.1.2.1 - car ', '01/Mar/2022:13:05:05  +0900] "GET /python HTTP/1.0" 200 2222']. 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: ['10.1.2.1', '-', 'car', '[01/Mar/2022:13:05:05', '+0900]', '"GET', '/python', 'HTTP/1.0"', '200', '2222']. and then you splice the list from indexes 3 to 5 (excluding 5). This will return the list: ['[01/Mar/2022:13:05:05', '+0900]'] 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: ['10.1.2.1 - car ', '01/Mar/2022:13:05:05  +0900', ' "GET /python HTTP/1.0" 200 2222'] 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

If this answer helped consider rating and marking brainliest :)

Answer:

user_num >= 0 or 0 <= user_num

Explanation:

You want to use one of the comparison operators, to solve this problem, and in this case you're going to specifically use: >= or <=, which is "greater than or equal to" and "less than or equal to", either can be used, it just depends where you place the numbers, kind of like how 10 >= 3 and 3 <= 10 are both true.

So in this case it says "non negative" number, this means that the number is greater than or equal to 0, The reason the equal to is included is because 0 is not negative. this means that you want to include it as well. So don't do user_num > 0, since that would exclude 0, which is not negative. So you're solution for the while loop will be:

while user_num >= 0:

   # code

or you can do

while 0 <= user_num:

   # code

Although I would probably go with user_num >= 0, since it seems to be the most understandable at a glance, although both should work.
