 # OO_Programming_Python
 ## Project 1
-Calculate Amortization, APR(annual percentage rate) and format them in a nicer and readable way from the given csv file about loan\
+1. Calculate Amortization, APR(annual percentage rate)
+2. Format them in a nicer and readable way
 
 ## Project 2
 ### Rules
-1. Initialize a 10x10 gridlines and randomly generate barrier in the path of the moving object.\
-2. The object will move one grid to the direction that the user clicks(namely, right, left, up, down).\
-3. Each time the object moves past a grid, the socre will be updated with +1. Each time the object moves past a barrier, the socre will be updated with +5.\
-### Functions:
-1. Display a panel containing previous top 4 scores, player names,and different functional buttons.\
-2. Display different contents as the user clicks different buttons. If the user wants to play, it will display grids(game panels) where user can click to move the object.\
-3. When the object hits the target area, the programme will calculate the score and display it in the beginning panel if it is among the new top 4 scores.\
-4. Get the top 4 game player's names and their scores after they move the object to a target area.\
-5. Update the panel containing top 4 scores, player names,and different functional buttons.\

+### General
+1. Display a panel containing previous top 4 scores, player names, and different functional buttons.
+2. Display corresponding contents as the user clicks different buttons. If the user wants to play, it will display grids(game panels) where user can click to move the object.
+3. When the object hits the target area, the program will calculate the score and display it in the beginning panel if it beats one of the existing top 4 scores.
+4. Get the top 4 game player's names and their scores after they move the object to a target area.
+5. Update the panel containing top 4 scores, player names, and different functional buttons.
 
-## Project 3: 
-1. Add diagnal movement function on the basis of project 2.\
-2. Sleep for a given time period defined by user.\
+## Project 3:
+### Improvements
+1. Add diagonal movement function on the basis of project 2.
+2. Sleep for a given time period defined by user.
 3. Display colorful alternating background when the object successfully reaches the target area within specific time periods.
 ### General
-This program is a game where the user has to complete a maze in the least amount of moves by avoiding tripwires.\
-It keeps track of players names, moves, and scores.\
-The home screen displays the top scores and enables the user to start new games while the field window is used for gameplay.
