The answer would be A.
The rest seem impractical.
True. If the list contains any elements that appear more than once, then it has duplicate elements and the variable has_dups is True.
What is variable?
Throughout computer programming, a variable is indeed a named container for a specific set of bits or type of data. A variable is indeed an abstract storage location with an associated symbolic name that holds some unidentified quantity of information made reference to as a value. Eventually, a memory address may be used to link or identify a variable. In addition to using the variable name or the variable itself, depending on circumstances, the stored value is typically referenced by the variable name. The name can be used independently of the precise information it represents thanks to the separation of name as well as content. During run time, a value can be bound to an identification number in computer source code.

Answer:
See Explanation
Explanation:
I'll assume the question is about the use of constants in QBasic because consonants do not have any special function or usage in QBasic.
In simple terms: In QBasic, constants are used to represent elements that do not change in value during program execution.
Take for instance, you intend to use 
in your program.
Its value is 
So, 3.142 will always be a constant in your program. One of the ways it can be used in a program is:
10 LET PI = 3.142
<em>The above represents a numeric constant. QBasic also have string constants.</em>
Answer:
from socket import *
hostname = input('Enter the host to be scanned: ')
ip_add = gethostbyname(hostname)
connections = [ ]
for i in range(133, 136):
s = socket(AF_INET, SOCK_STREAM)
conn = s.connect_ex((ip_add, i))
print(conn)
connections.append(conn)
if 0 in connections:
print ('Host is online')
s.close()
else:
print ('system is unreachable')
Explanation:
The python source code above scans for all the available range of ports in the provided hostname, if any port is available, the host is online else the program print the error message "system is unreachable.
