Write a program to Student height record program for a school in Python

The Python code defines a class called SchoolHeightRecords that allows you to manage height records of students. Here's a breakdown of the code:

The SchoolHeightRecords class is defined with the following methods:

__init__: Initializes an empty dictionary called student_records to store student names and their corresponding heights.
add_student: Adds a new student's height to the student_records dictionary.
remove_student: Removes a student's record from the student_records dictionary by providing the student's name.
find_student_height: Retrieves the height of a student by providing their name. If the student is not found, it returns None.
display_records: Displays all the student height records stored in the dictionary.

An instance of the SchoolHeightRecords class is created with the variable school_records.
A menu is displayed to the user with the following options:

1. Add Student Height
2. Remove Student Height
3. Find Student Height
4. Display All Records
5. Quit

The program enters a loop where the user is prompted to enter their choice.
Depending on the user's choice, the corresponding method of the SchoolHeightRecords instance is called to perform the desired operation. The user can add, remove, find, or display student height records, or quit the program.
If the user provides an invalid choice, they are notified with the "Invalid choice" message and prompted to try again.

The code allows you to interactively manage student height records, and it will continue running until the user chooses to quit (option 5).

One note is that the heights are stored as strings in the student_records dictionary. If you need to perform numerical operations with the heights, you should convert them to integers or floats before using them in calculations.
