    To write your first software application using Python, you can follow these steps:

    1. Install Python: First, you need to install Python on your computer. You can download the latest version of Python from the official website at python.org and follow the installation instructions.

    2. Choose a text editor or IDE: You can write Python code in any text editor like Notepad or use an Integrated Development Environment (IDE) like PyCharm, Visual Studio Code, or IDLE.

    3. Write your Python code: Open your text editor or IDE and start writing your Python code. Here is an example of a simple “Hello, World!” program in Python:

    

    

    print("Hello, World!")
    

    

    
4. Save your Python file: Save your Python code with a “.py” extension, for example, “hello.py”.
    

    
5. Run your Python program: Open a terminal or command prompt, navigate to the directory where your Python file is saved, and type `python hello.py` to run your program. You should see the output “Hello, World!” displayed on the screen.
    

    By following these steps, you can create and run your first software application using Python.

    One way to remove duplicates from a list in Python is to convert the list to a set, which automatically removes duplicates due to its nature of storing unique elements. Then, you can convert the set back to a list if needed. Here is a simple example:my_list = [1, 2, 2, 3, 4, 4, 5]unique_list = list(Read more

    print(unique_list)
    

    ```
    

    Alternatively, you can use a list comprehension to create a new list with unique elements:
    

    ```python
    

    my_list = [1, 2, 2, 3, 4, 4, 5]
    

    unique_list = []
    

    [unique_list.append(x) for x in my_list if x not in unique_list]
    

    print(unique_list)
