The program based on the information given is illustrated below.
<h3>How to illustrate the program?</h3>
It should be noted that a computer program is a set of instructions in a programming language for the computer to execute.
Based on the information, the program is illustrated thus:
Code:
import pickle
#function to read birds data
def readBirdsData():
try:
birdsFile = open("birdsData","rb")
birdWatcher = pickle.load(birdsFile)
birdsFile.close()
birdWatcher ={}
except EOFError:
birdWatcher ={}
return birdWatcher
#function to write the data into file using pickle
def writeBirdsData(birdWatcher):
if birdWatcher == {} :
return
sorted(birdWatcher)
birdsFile = open("birdsData","ab")
pickle.dump(birdWatcher,birdsFile)
birdsFile.close()
#function to display birds data in sorted order
def displayBirdsData(birdWatcher):
print("Name\t\tCount")
print("========\t===========")
for key in sorted(birdWatcher.keys()):
print("{}\t\t{}".format(key,birdWatcher[key]))
#main function
def main():
birdWatcher = readBirdsData()
print("Bird Counter Program")
print ("\nEnter 'x' to exit\n")
name = input("Enter name of bird: ")
while True:
#break the loop if x is entered
if name == 'x':
#if the name exists in dictionary then increase the value
if the name in birdWatcher.keys():
birdWatcher[name] = birdWatcher[name] + 1
else:
#dd it otherwise
birdWatcher[name] = 1
name = input("Enter name of bird: ")
displayBirdsData(birdWatcher)
writeBirdsData(birdWatcher)
#driver code
if __nam__ == '__main__':
main()
