In this course, you will get a comprehensive overview of Python. You will start by laying the foundation and learning the introductory topics like operators, conditional statements, functions, loops, assignment statements, and more. You will then move onto more advanced topics such as classes and inheritance, iterators, list comprehensions, and dictionaries. Along with this, you will also get to explore the concept of testing and take a look at how GUI applications can be designed using Tkinter, Python's standard GUI library. 

By the time you're done, you'll be able to hit the ground running and be equipped with the tools that will allow you to be productive in Python.

Python 3: From Beginner to Advanced

def student_names(filename):
    mylist = []

    with open(filename) as f:
        for line in f:
            k = line.split(' : ')
            myval = []
            
            for num in k[1].split():
                num = int(num)
                myval.append(num)

            total = sum(myval)
            if (total > 10):
                mylist.append(k[0])
    return mylist

filename = 'test.txt'
result = student_names(filename)
print(result)

## Explanation

The first thing we need to do is read the text file using the `open` command. Observe this in **line 4** of the above code. Next, at **line 5**, we can use a `for` loop to traverse over the contents of the text file.

> **Note:** Since we are using the `with` keyword, we don't need to **close** the text file. 

At **line 6**, we use the `split` method with **space-colon-space** (`:`) as the **delimiter** to split the contents of the text file into two portions. An example of this is shown below:

```python
['Jim', '1 5 4 3']
```

> **Note:** As you can see in the example above, the `split` method creates a list. 

After this, at **line 9**, we use the `split` method on the student marks (these can be accessed by indexing) to separate each of them from one another. Next, we use a `for` loop to iterate over them. A **lines 10 and 11**, we convert these marks to the integer data type using the `int` conversion function (since reading from a text file returns its contents in the form of a string) and add them to the `myval` list, which we declared at **line 7**. 

Now, from **lines 13 to 14**, we simply sum all the contents of this `myval` list and check to see if the sum is greater than 10 or not. If it is, we add the name of that student to `mylist`, which will contain our final results.
