The section called Breaking Substitution Ciphers (p. 166) describes a "random substitution cipher," in which each letter of the

alphabet is randomly replaced with a different letter or character i.e. A→T, B→F… What makes a random substitution cipher more secure than a Caesar shift?

Answer: Compared to a Caesar shift, the random substitution cipher offers many more possibilities, because the encryption is randomly chosen.

Explanation:

A Caesar Cipher is also a type of substitution cipher, but instead of doing it randomly, it shifts the alphabet by a certain number of characters. Therefore, the answer to decrypt the message is simply to figure out that number.

For this problem, you will write a function standard_deviation that takes a list whose elements are numbers (they may be floats
Evgesh-ka [11]

Answer:

  1. import math  
  2. def standard_deviation(aList):
  3.    sum = 0
  4.    for x in aList:
  5.        sum += x  
  6.    
  7.    mean = sum / float(len(aList))
  8.    sumDe = 0
  9.    for x in aList:
  10.        sumDe += (x - mean) * (x - mean)
  11.    
  12.    variance = sumDe / float(len(aList))
  13.    SD = math.sqrt(variance)
  14.    return SD  
  15. print(standard_deviation([3,6, 7, 9, 12, 17]))

Explanation:

The solution code is written in Python 3.

Firstly, we need to import math module (Line 1).

Next, create a function standard_deviation that takes one input parameter, which is a list (Line 3). In the function, calculate the mean for the value in the input list (Line 4-8). Next, use the mean to calculate the variance (Line 10-15). Next, use sqrt method from math module to get the square root of variance and this will result in standard deviation (Line 16). At last, return the standard deviation (Line 18).

We can test the function using a sample list (Line 20) and we shall get 4.509249752822894

If we pass an empty list, a ZeroDivisionError exception will be raised.
