I am having trouble with this python question. I am in a beginner level class also so any solution that isn't too complex would

The code:

filename = input("> ")

with open(filename, "r") as file:

items = file.read()

items = items.split("\n")

for index, item in enumerate(items):

items[index] = item.split("\t")

for item in items:

if item[3] == "Available":

print(f"{item[1]} ({item[0]}) -- {item[2]}")

Explenation:

1. We make the user enter the file's path, in our case "food.txt". This does only work if the .txt file is in the <u>same</u> directory as our code.

2. We get the content of our .txt file with the "open" function. If we use the "open" function inside of a "with" statement we don't have to deal with closing the file after we opened it. The file will close as soon as we exit the statement. The argument "r" indicates that we only want to read the file, not do anything else with it.

3. However the variable "file" doesn't contain the <u>contents</u> of "food.txt", only the class object of our file (if you try "print(file)" you'll only get nonsense). We can simply get the content of the file by calling ".read()" after.

4. We can separate this long str using the ".split()" function. The split function seperates a string by another sertain string (in our case "\n", since the different items are seperated by a newline). Now "items" is a list of strings.

5. Next we go through all items in "items" and separate them by "\t", again using the ".split()" function. Enumerate makes a list of indexes and values from another list (in our case, "items").

6. Now we have a list of lists of strings. The only thing left to do is go through every item and print it if the item's third item is equal to "Available" (notice that this is case-sensative). And print out the result in the desired format.

The code works for me, please ask me if there is anything you don't understand (or if the code is incorrect). Happy to help :D

Look at the following code.int x = 7;int *iptr = &x;What will be displayed if you send the expression *iptr to cout ? What h

masha68 [24]

Answer:

The answer to the given question can be given as:

The value of *iptr is 7. and the value of iptr is dynamic.

Explanation:

In the c++ code, it is defined that x is an integer variable that assigns a value which is 7. Then we define a pointer variable that is *iptr. This variable holds an address of the x variable. When we print the value of the iptr variable. if we use the expression *iptr to print value of the pointer variable by cout that is used in c++ for pint values. so the value of the iptr is 7. If we use the expression iptr sent to cout so we show the address of the variable x. In the pointer, it manages the addresses of dynamically allocated so the address of the variable is changed on execution time.
