What is the python code for the function def readFloat(prompt) that displays the prompt string, followed by a space, reads a floating-point number in, and returns it. Here is a typical usage:
salary = readFloat("Please enter your salary:")
percentageRaise = readFloat("What percentage raise would you like?")
assume python does not define count method that can be applied to a string to determine the number of occurances of a character within a string. Implement the function numChars that takes a string and a character as arguments and determined and returns how many occurances of the given character occur withing the given string
Consider the ER diagram of online sales system above. Based on the diagram answer the questions below,

For the moment you can leave it empty while you work on creating classes that represents characters in the game. • Write an abstract class Fighter which has the following private fields: - A Tile field named position, representing the fighter's position in the game. A double field named health, representing the fighter's health points (HP). An int field named weaponType, representing the type of weapon the fighter is using. This value is used to rank different weapon types: higher values indicate higher weapon ranks. -An int field named attackDamage, representing the fighter's attack power.

We are not interested in information about a child once the parent leaves the company. Draw an ER diagram using Crows Foot notation that captures this information.
