Create a Python project fly_drone. Add a Python file drone. py to this project. Define a class Drone in this file. This class has the following five methods: (a) init : Create two instance variables to store the speed and the height of the drone. Initialize them to 0.0. This method has no parameters other than self and no return value. (b) accelerate : Increase the speed of the drone by 10. This method has no parameters other than self and no return value. (c) decelerate : Decrease the speed of the drone by 10. The new speed cannot be negative. This method has no parameters other than self and no return value. (d) ascend : Increase the height of the drone by 10. This method has no parameters other than self and no return value. (e) descend : Decrease the height of the drone by 10. The new height cannot be negative. This method has no parameters other than self and no return value.

Following are the python code to this question:

class Drone: #define class

def __init__(self): #define constructor

self.speed = 0.0 #define variable speed and assign value

self.height = 0.0 #define variable speed and assign value

def accelerate(self): #define method accelerate

self.speed += 10 #add value 10 in speed

def decelerate(self): #define method decelerate

if(self.speed >= 10): #define condition that checks speed value is greater then equal to 10

self.speed -= 10 #subtract value of speed by 10

else: #else block

self.speed = 0 #assign value 0 in speed variable

def ascend(self): #define method ascend

self.height += 10 #add value 10 in height

def descend(self): #define method descend

if(self.height>=10): #define condition that checks height value is greater then equal to 10

self.height -= 10 #subtract value of height by 10

else: #else block

self.height = 0 #assign value 0 in variable height

drone = Drone() #create class object

f = True #define variable f and assign bool value

while(f): #define that calculate value

c = int(input("please select by your choice: for accelerate = 1, for decelerate = 2, for ascend = 3,for descend = 4,for exit = 0: "))

#define variable that take input from user and convert value in integer

if(c==1): #check c value is equal to 1

drone.accelerate() #call accelerate method

Output:

Please find the attachment.

Explanation:

In the code part there are some code which can't inserted in so, we give the image of the full code, please find in attachment.

In the python code, a class "Drone", is declared, inside the class, a constructor, and four methods "accelerate, decelerate, ascend, and descend" is declared.

In the "accelerate and descend" method we increment and decrements its variable value by 10, and method "decelerate and ascend" uses conditional statement that checks speed and height variable value is greater then equal to 10, if the value is true it will subtract the value by 10, otherwise set the value 0, and in next line, the class object is created. In the last step, a c variable is declared, that input from the user according to choice, and convert the value into the integer. In this, a conditional statement is used, that checks "c" value and call the above method, which can be described in the given example:if the value is 1, it will call accelerate method, otherwise it will go to else if section. In this else if value is equal to 2, it will call decelerate method, if this condition is false, it will check another value, that is value is equal to 3, in this, it will call ascend method.if the value is equal to 4, it will call descend method.If above condition is false, it will print speed and height value.
