Answer:

# In the new version of python is available the functions mean() an variance()

# In the module of statistics

i = 0 #Var to input the elements

l = [] #Var to store the elements on a list

while(i>0):

    print("In put a positive number to add in the list or negative to exit ")

    i = input()

    l.append(i)

    print("The mean of the all elements is: " + mean(l) )

    print("The variance of the all elements is: " + variance(i) )

Explanation:

At present, you can use in the <em>news python's verison</em> e.g. (python 3.7) the <em>statistics module</em> and use functions like <em>mean(), variance(), stdev()</em> and many others.

In the first step you create two variables, i to recieve the inputs of a loop and l to store all the elements recieved in the<em> i</em> variable. after that you pass as an argument the list that you stored before and get the <em>mean()</em> and <em>variance()</em> of the all elements in the list.

I hope it's help you.

What classes should I take in high-school for majoring in computer science?
Gala2k [10]

Answer:

Computer science are the disciplines that study information, computing and the applications or ecosystems where they are developed. It is a science that comes from applied mathematics and has 3 branches that are quite well known. On the one hand we have software engineering, secondly theory as such (primary study of algorithms and data, etc.) and finally the application of the amalgam of the first two, which end up resulting in disciplines such as big data, cybersecurity or computer security, machine learning, artificial intelligence, etc. However, we are talking about a very broad science with various branches of work. Technological advances that have improved the scope of education, now allow us to develop in specific skills and computer science is one of the macro careers that have benefited the most thanks to the diversity of subjects it encompasses. This is where the on-demand courses available on the edX platform come in. Computer scientists are in one of the best times for their career advancement. We invite you to be part of the technological development and information and computing technologies through online courses.
