New Feedback for Day 1

Nobody has claimed this yet.

#### Readme
- All good!

#### Python_GUI_day1.py

- [x] Further break down the code in functions based on the logic of what they do. For example, you could have the following functions:
- `create_data`
- `create_window1` (internally calls `create_plot`)
- `create_window2`
- `create_plot` (internally calls `create_data`)
- `create_menu`
- [x] Then, in the `if __name__ == "__main__":` section at the end, you call these in sequence:

```python
if __name__ == "__main__":
dpg.create_context()
dpg.create_viewport()
create_window1()
create_window2()
create_menu()
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()
```

- [x] Document each function with docstrings:

```python
def create_window1():
"""Create window 1

This window contains several widgets like buttons, checkboxes, texts...
as well as an static plot to illustrate the capabilities of dearpygui.

For each widget, parameter pos=[x,y] (x is the horizontal position and
y is the vertical position) can be used to set the position of the widget.
If not set, the widget will be placed automatically. In this case, the
radio button will be set below the checkbox widgets rather than side by side.
"""
# And here goes the code...
```

Review Python_GUI_day1.py against the completed checklist, starting with the function breakdown and the if __name__ == "__main__": section. Confirm that the listed functions and docstrings are present; the issue text marks all requested work as complete.
