Answer 1

Code:

#matplotlib is a module that contains ploting functions
import matplotlib.pyplot as plt
#MAT = Monthly Average Temperature
#x1 is the MAT of the year 2001
x1=[42, 43, 55, 50, 56, 54, 60, 48, 53, 50, 69, 55]
#x2 is the MAT of the year 2002
x2=[75, 75, 89, 56, 63, 55, 61, 53, 62, 55, 58, 43]
#x3 is the MAT of the year 2003
x3=[73, 55, 57, 53, 60, 47, 53, 65, 64, 74, 52, 73]
#these are used to add additional properties for the plot
i,j = plt.subplots()
#all the names of months are stored to label them on the X axis
months=['Jan', 'Feb', 'Mar', 'Apr', 'May','Jun','Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
#please open the output graph in full screen
#bar function is used to plot bar graph
#1st parameter is the X axis values
#2nd parameter is the Y axis values
#color is used to define the color of the bar
#label is used to define the colors for the resective years
plt.bar(list(range(1,13)),x1,color="green",label="2001")
plt.bar(list(range(13,25)),x2,color="red",label="2002")
plt.bar(list(range(25,37)),x3,color="blue",label="2003")
#set_xticklabels is used to set labels for X axis
#as there are 3 years each year has 12 months so months*3
j.set_xticklabels(months*3)
#xticks is used to define 36 labels
plt.xticks(list(range(1,37)))
plt.xlabel('Months of respective year')
plt.ylabel('Monthly average temperature')
plt.title('Temperature vs Months')
#legend is used to disply the label
plt.legend()
#show is used to display the plot
plt.show()
Screenshot:

Output:
