Question
NEED HELP WITH THIS (PYTHON)
Create two lists containing names and averages (float values) of five students and plot a pie chart and a bar chart.
Pie chart example:
import matplotlib.pyplot as plt
import numpy as np
y = np.array([35, 25, 25, 15])
mylabels = ["Apples", "Bananas", "Cherries", "Dates"]
plt.pie(y, labels = mylabels)
plt.show()
Bar Chart example:
import matplotlib.pyplot as plt
import numpy as np
x = np.array(["A", "B", "C", "D"])
y = np.array([3, 8, 1, 10])
plt.bar(x,y)
plt.show()

- Write a program that animates the linear search algorithm. Create a list that consists of 20 distinct numbers from 1 to 20 in a random order. The elements are displayed in a histogram, as shown in Figure 10.17. You need to enter a search key in the text field. Clicking the Step button causes the program to perform one comparison in the algorithm and repaints the histogram with a bar indicating the search position. When the algorithm is finished, display a dialog box to inform the user. Clicking the Reset button creates a new random list for a new start.arrow_forward### Import section# 3 necessary statements for numerical plotting in Jupyterimport numpy as npimport matplotlib.pyplot as plt %matplotlib inline# Factorial comes from 'math' packagefrom math import factorial ### Initialization section#array of derivatives at 0 compute by handderiv = np.array([1, 0, -1, 0, 1, 0, -1, 0])# degree of Taylor polynomialN=len(deriv)-1 # Max abs. value of N+1 deriv on interval (Compute using calculus)# (used in the remainder formula)# @@@ The N+1 derivative will be proportional to cosine, and |cos| is always # @@@ less than 1maxAbsNplus1deriv=1 #array with h valuesh = np.arange(-3,3.005,0.01) # Give the expansion point for the Taylor seriesexpansion=0 # Create an array to contain Taylor seriestaylor = np.zeros(len(h)) ### Calculation section#calculate Taylor series for all h at once using a loopfor n in range(N+1): taylor = taylor + (h**n)/factorial(n)*deriv[n] #actual function values actualFn = np.cos(expansion+h) #error actual and taylor…arrow_forwardpython help, please show all steps and include comments Write a function largerLst() that takes a list of numbers (i.e., int or float values) as a parameter and returns a new list constructed out of it. The list returned has all the values in the parameter list that are larger than the element immediately to their right, that is, larger than their right neighbor. If the parameter list is empty or there are no values larger than their right neighbor, then the function returns an empty list. Note that the last element in the list will never be included in the list returned since it does not have a right neighbor. The function should not change the parameter list in any way. Note that a correct solution to this problem must use an indexed loop That is, one that makes a call to the range() function to generate indices into the list which are used to solve the problem (Review lecture notes 8-1). A solution that does not use an indexed loop will not be accepted. Note in particular that you…arrow_forward
