Use simple python
Devise an experiment that compares the performance of the del operator on lists and dictionaries.
a graph displaying the timings of those operators
#source code:
import timeit
import matplotlib.pyplot as plt
list=["vishnu","vardhan","namana","siva","nagsai","sai"]
dict={"name":"vishnu","class":"sf","age":17,"nicename":"toms"}
#list element delete opeation
start=timeit.timeit()
del list[3]
end=timeit.timeit()
list_time=end-start
print("list delation time:",list_time)
#dictionary element delete opeation
start=timeit.timeit()
del dict["class"]
end=timeit.timeit()
dict_time=end-start
print("list delation time:",dict_time)
plt.plot(["list_time","dict_time"],[list_time,dict_time],"ro")
plt.show()

Deletion of List Elements The del statement removes an element or slice from a list by position. The list method list.remove(item) removes an element from a list by it value (deletes the first occurance of item) For example: a = ['one', 'two', 'three'] del a[1] for s in a: print(s) b = ['a', 'b', 'c', 'd', 'e', 'f', 'a', 'b'] del b[1:5] print(b) b.remove('a') print(b) # Output: ''' one three ['a', 'f', 'a', 'b'] ['f', 'a', 'b'] ''' Your textbook...
In Python Please use the same USPopulation.txt file from Project 8 as input data. For this project, read the data into a list of lists (a 2-dimensional list, 4 decades, each decade with 10 years). Compute the annual change in the population, and the year with the maximum and minimum population change. Using Anaconda, plot a graph for each decade's population change. The attached file USPopulation.txt contains the US population in thousands, during the years 1950 through 1990. The first...
Next, create a simple benchmark experiment using the timeit module as we did in class. • Run each of your functions 1 time (e.g. quad_timest timeit(number 1)) for list sizes ranging from 1,000 to 20,000 in increments of 1,000. You will notice that the quadratic time function really starts to slow down as the size of the list Increases Display a table the run times (should look something like this: ratio 906 Size Tinear 3000, 0.00000 15000 3000, 0.0001202000. 5000,...
Classification in Python: Classification In this assignment, you will practice using the kNN (k-Nearest Neighbors) algorithm to solve a classification problem. The kNN is a simple and robust classifier, which is used in different applications. The goal is to train kNN algorithm to distinguish the species from one another. The dataset can be downloaded from UCI Machine Learning Repository: https://archive.ics.uci.edu/ml/machine-learning-databases/iris/ (Links to an external site.)Links to an external site.. Download `iris.data` file from the Data Folder. The Data Set description...
Use python!!! need to match the execution result that is provided. Part One – Keyword Arguments and Default Values Write an invoice function. The function will generate a simple invoice and will have two required arguments and two keyword arguments. The two required arguments are unitPrice and quantity. The first keyword argument is shipping, and it has a default value of 10. The second keyword argument is handling, and it has a default value of 5. Test it twice from...

I need to make (yeast fermentation) lab
report.
This is the lab experiment and results:
This is a guide to making the lab report:
General Biology BIO121 Yeast Fermentation Lab Introduction Organisms stay alive by the utilization of energy through metabolism. The energy acquiring pathways in photosynthesis convert radiant energy from the sun into the chemical bond energy of carbohydrates. This photosynthetic process is limited to the producers or autotrophs, which include plants, photosynthetic bacteria and some protists....
This activity needs to be completed in the Python language. This program will simulate part of the game of Poker. This is a common gambling game comparing five-card hands against each other with the value of a hand related to its probability of occurring. This program will simply be evaluating and comparing hands, and will not worry about the details of dealing and betting. Here follow the interesting combinations of cards, organized from most common to least common: Pair --...
please use python and provide run result, thank you!

For this assignment you will have to investigate the use of the Python random library's random generator function, random.randrange(stop), randrange produces a random integer in the range of 0 to stop-1. You will need to import random at the top of your program. You can find this in the text or using the online resources given in the lectures A Slot Machine Simulation Understand...
Chapter 8
Python Case study Baseball Team Manager
For this case study,
you’ll use the programming skills that you learn in Murach’s
Python Programming to develop a program that helps a
person manage a baseball team. This program stores the data for
each player on the team, and it also lets the manager set a
starting lineup for each game. After you read chapter 2, you can
develop a simple program that calculates the batting average for a
player. Then,...
