Scientific Computing with Python

About the Projects

This repository contains my solutions to the projects in "Scientific Computing with Python" course from freeCodeCamp.

Project list:

Arithmetic Formatter

A Python program that provides a function for formatting a list of arithmetic problems vertically and side-by-side. Optionally, it can display the answers alongside the problems.

Example

Function Call:

arithmetic_arranger(["32 + 698", "3801 - 2", "45 + 43", "123 + 49"])

Output:

   32      3801      45      123
+ 698    -    2    + 43    +  49
-----    ------    ----    -----

Function Call:

arithmetic_arranger(["32 + 8", "1 - 3801", "9999 + 9999", "523 - 49"], True)

Output:

  32         1      9999      523
+  8    - 3801    + 9999    -  49
----    ------    ------    -----
  40     -3800     19998      474

Time Calculator

A Python program to add time to a 12-hour clock format, with optional day of the week support.

Example

Function Call:

add_time("3:00 PM", "3:10")
# Returns: 6:10 PM

add_time("11:30 AM", "2:32", "Monday")
# Returns: 2:02 PM, Monday

add_time("11:43 AM", "00:20")
# Returns: 12:03 PM

add_time("10:10 PM", "3:30")
# Returns: 1:40 AM (next day)

add_time("11:43 PM", "24:20", "tueSday")
# Returns: 12:03 AM, Thursday (2 days later)

add_time("6:30 PM", "205:12")
# Returns: 7:42 AM (9 days later)

Budget App

A Python program to initialise a budget category object which allows depositing, withdrawing, as well as transferring funds to another budget category object.

Additionally, it can also return a formatted string representation of the category ledger as well as creating visual charts that depict the percentage of spending in each category.

Example

Here is an example of the output when printing out the Category object:

*************Food*************
initial deposit        1000.00
groceries               -10.15
restaurant and more foo -15.89
Transfer to Clothing    -50.00
Total: 923.96

Here is an example of the output when printing out Percentage spent by category chart:

Percentage spent by category
100|          
 90|          
 80|

 60| o        
 50| o        
 40| o        
 30| o        
 20| o  o     
 10| o  o  o  
  0| o  o  o

Polygon Area Calculator

A Python project with a Rectangle class and a Square class, showcasing object-oriented programming. The Rectangle class handles width, height, area, perimeter, diagonal, picture representation, and fitting calculations. The Square class, a subclass of Rectangle, adds single-side handling and method access while maintaining string representation integrity.

Example

Function Call:

rect = shape_calculator.Rectangle(10, 5)
print(rect.get_area()) # Returns: 50

rect.set_height(3)
print(rect.get_perimeter()) # Returns: 26
print(rect) # Returns: Rectangle(width=10, height=3)

"""
Returns: 

**********
**********
**********

"""
print(rect.get_picture())


sq = shape_calculator.Square(9)
print(sq.get_area()) # Returns: 81

sq.set_side(4)
print(sq.get_diagonal()) # Returns: 5.656854249492381
print(sq) # Returns: Square(side=4)

"""
Returns:

"""
print(sq.get_picture()) # Returns:

rect.set_height(8)
rect.set_width(16)
print(rect.get_amount_inside(sq))
