How do you do this? Make sure each step is clear and have functions. PYTHON Statisticians use the concepts of mean and standarddeviation to describe a collection of numbers. The mean isthe average value of the numbers and the standard deviationmeasures the spread or dispersal of the numbers about themean. The formally, if X1, X2, X3, ..., Xn is a collection ofnumbers then the mean is:m= X1+X2 txgtint Xnnand the standard deviation is:(x q-m]?+(xz= m)²+ (X3-m) t.+&m m Have the user enter number of exam scores you would like to find the average and standard deviation.Write a program to calculate the mean standard deviation of the exam scores, assign letter grades toeach exam score, ES, as follows, and then display information about the exam scores and grades:ESZmtl.5s>A$$m+o.5s\le ES$ $ m-0.5s\le ES$ $ m-1.5sl le ES$ $ ESShow your answers with at least 10 grades entered to validate your code works. Below is an example ofhow your outputs can be displayed but not required.Number of scores: 14Average score: 71.0Standard deviation of scores: 14.42GRADE DISTRIBUTION AFTER CURVING GRADES.А:2B:1 C:6 D:4F:1

Write a program that accepts two four-digit binary numbers, converts them to decimal values, adds them together, and prints both the decimal values and the result of the addition. Requirements: Functionality. (80pts) No Syntax Errors. (80pts*) *Code that cannot be compiled due to syntax errors is nonfunctional code and will receive no points for this entire section. Clear and Easy-To-Use Interface. (10pts) Users should easily understand what the program does and how to use it. Users should be prompted for input and should be able to enter data easily. Users should be presented with output after major functions, operations, or calculations. All the above must apply for full credit. Users must be able to enter a 4-bit binary number in some way. (10pts) No error checking is needed here and you may assume that users will only enter 0’s and 1’s, and they will only enter 4 bits.

About beginner python programming: - Imagine that you want to send a congratulations message and would like to repeat those congratulations many timestimes in the message. Something like “Happy Birthday!! Happy Birthday!! Happy Birthday!! ..." until fullyour friend's screen. You can write once and copy and paste. Then you notice, there in the middleof the way, that you typed wrong...Ouch! Now that you know how to use Python to make it work for you,do a function that receives as input a text and the desired number of repetitions and returns astring composed of n repetitions of this text. - so I know how to input a specific word in python and multiply it by a number but not how to input a string as a variable (which can be any word, text, expression) and multiply it.
fast in python thanks
