inp = int(input("Enter an integer: "))
#print input
print("The integer is: ",inp)
break
#if input is not integer
except ValueError:
#print message
print("Wrong: try again.")

Check your DNS settings
Explanation:
Different errors may occur when setting up your computer to connect to the internet, one of which is described in the question above.
The DNS (Domain Name System) is responsible for redirecting domain names to their physical IP address. Instead of remembering every IP address of sites you visit frequently, domain names are used for easy remembrance, the DNS makes the matching of domain names to IP addresses possible.

- Check to see if "Obtain DNS server address automatically" is selected, if it is selected,
- Click on the radio button under it "Use the following DNS server address"
- Enter the DNS address you want to use
- Click Ok and close the window.
The problem should be resolved.
Answer:
Explanation:
The following code is written in Java, the function takes in a list with the previous day's values. The function then uses that list, loops through it and multiplies each individual value by 2 and returns the modified list. The first red square represents the test case for the function, while the second red square in the image represents the output.
public static ArrayList<Integer> doubleIt(ArrayList<Integer> mylist) {
for (int x = 0; x<mylist.size(); x++) {
mylist.set(x, mylist.get(x)*2);
}
return mylist;
}
