Program for Hackerrank String Object Manipulation Code in Python

Python - Hackerrank String Object Manipulation Program

Python - Hackerrank String Object Manipulation Program

Source Code

Aim :

    To program a Hackerrank string object manipulation code in python.

Algorithm :

• Get the required input from the user by using input statement for 'q'(number of vehicle) and 'args'(Type of vehicle with respective speed limit).
• Instantiation the Car() and Boat() class and their function with passing parameter as 'args'.
• Write the required __str__ function definition for the class Car() and Boat().
• The required information is successfully updated in the given file (junk.txt).

Program :

#!/bin/python3

import math

import os

import random

import re

import sys

class Car:

    def __init__(self, max_speed, speed_unit):

        self.speed = max_speed

        self.unit = speed_unit

    def __str__(self):

            return "Car with the maximum speed of {} {}".format(self.speed, self.unit)

class Boat:

    def __init__(self, max_speed):

        self.speed = max_speed

    def __str__(self):

            return "Boat with the maximum speed of {} knots".format(self.speed)

if __name__ == '__main__':

    os.environ['OUTPUT_PATH'] = 'junk.txt'

    fptr = open(os.environ['OUTPUT_PATH'], 'w')

    q = int(input("Enter the number of vehicle : "))

    queries = []

    for _ in range(q):

        args = input("Enter vehicle with respective speed unit : ").split()

        vehicle_type, params = args[0], args[1:]

        if vehicle_type == "car":

            max_speed, speed_unit = int(params[0]), params[1]

            vehicle = Car(max_speed, speed_unit)

        elif vehicle_type == "boat":

            max_speed = int(params[0])

            vehicle = Boat(max_speed)

        else:

            raise ValueError("invalid vehicle type")

        fptr.write("%s\n" % vehicle)

    fptr.close()

Output :

Enter the number of vehicle : 

2

Enter vehicle with respective speed unit : 

car 100 kmph

Enter vehicle with respective speed unit : 

boat 82

Text That Appear On A Given File Are Below :

Car with the maximum speed of 100 kmph
Boat with the maximum speed of 82 knots
