In a typical office, biometric authentication might be used to control access to employees and registered visitors only. We know the system will have some false negatives, some employees falsely denied access, so we need a human override, someone who can examine the employee and allow access in spite of the failed authentication. Thus, we need a human guard at the door to handle problems as well as the authentication device; without biometrics, we would have had just the guard. Consequently, we have the same number of personnel with or without biometrics, plus we have the added cost to acquire and maintain the biometrics system. Explain the security advantage in this situation that justifies the extra expense.
The security advantage in this situation that justifies the extra expense is that these Biometric devices is one that separates the handling of issues regarding biometric information from the system operating system.

Explanation:
>>> A = [21, 'dog', 'red'] >>> B = [35, 'cat', 'blue'] >>> C = [12, 'fish', green'] >>> E = [A, B, C] What is the value of E1 2
The value of E[1][2] is 'blue'
How to determine the value of E?The code segment is given as:
A = [21, 'dog', 'red']
B = [35, 'cat', 'blue']
C = [12, 'fish', 'green']
E = [A, B, C]
The above code segment is written in Python, and the lists A, B and C are merged to form list E
This means that list E would be a two-dimensional list.
So, the value of E is [[21, 'dog', 'red'], [35, 'cat', 'blue'], [12, 'fish', 'green']]
Rewrite as:
E = [[21, 'dog', 'red'],
[35, 'cat', 'blue'],
[12, 'fish', 'green']]
The element at E[1][2] is the element at the second row and the third column.

A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is:
1712 the output is: 1712 is a leap year. Ex: If the input is: 1913 the output is: 1913 is not a leap year
Your program must define and call the following function. The function should return true if the input year is a leap year and false otherwise. def is_leap_year(user_year) Note: This is a lab from a previous chapter that now requires the use of a function,
Based on the fact that the program should be able to return true if the input is a leap year, and false if the input is not, the program is shown below.
What program will return true if it is a leap year?In order to make a program that tells whether a year is a leap year or not, you need to start off with the definition:
def is_leap_year(user year):
Then continuing the program, the full code would be:
def is_leap_year(user_year):
if(user_year % 400 == 0):
return True
elif user_year % 100 == 0:
return False
elif user_year%4 == 0:

if __name__ == '__main__':
user_year = int(input())
if is_leap_year(user_year):
print(user_year, "is a leap year.")
else:
print(user_year, "is not a leap year.")
