Hi Everyone, I have just received a project in order to build a python program for a safari park including being tickets (adding discounts), keeping note of their time (one car is maximum allowed for two hours ) and making sure everything works well, like the safety of the lions when they visit a lion, etc. Like I need to make sure that all the windows of the passengers are closed when they visit them. Any suggestions on how I can do so and an example code will be really appreciated.

Write a program that prompts the user to input a string. the program then uses the function substr to remove all the vowels from the string. for example, if str = "there", then after removing all the vowels, str = "thr". after removing all the vowels, output the string. your program must contain a function to remove all the vowels and a function to determine whether a character is a vowel.

Pp 4.1 design and implement a class called sphere that contains instance data that represents the sphere’s diameter. define the sphere constructor to accept and initialize the diameter and include getter and setter methods for the diameter. include methods that calculate and return the volume and surface area of the sphere (see pp 3.5 for the formulas). include a tostring method that returns a one-line description of the sphere. create a driver class called multisphere, whose main method instantiates and updates several sphere objects.
