# Calculator

 A calculator made with Python 3.8

 

 ## What have I learned with the project?

 #### GUI Design

 While using the PyQt5 Designer tool, I was able to learn about the software's workplace and how to use it in code to display whatever I want.

 #### Counting, separating and controlling strings

My calculator software was made in such a way that everytime you press a button, it adds it to a string displayed on top of the window, or it manipulates the string to involve certain numbers within functions.

```python

count = count[:index] + 'sqr(' + count[index:] + ')'

# the code above puts latest numbers after an operator (+, -, * or /) in between square function

# 'index' represents those numbers 

```

Once you press `=` the program uses `eval()` to calculate the string

 

 ## Setting up

  Assuming you already have Python and `pip` installed, to run the program you will need to get the following packages:

  * PyQt5

  * Regex

  * Math

  For that, you just need to use the commands bellow in your Command prompt:

  ```

  > pip install pyqt5 regex math

  ```

Now you should be able to use it by running `script.py`
