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

What will the output of the following code be?

```python
class Class_Blue:
	def blue_tag(self):
		print("B", end=' ')

class Class_Orange:
	def orange_tag(self):
		print("O", end=' ')

class Class_Green(Class_Orange, Class_Blue):
	def green_tag(self):
		print("G", end=' ')

class Class_Yellow(Class_Orange):
	def yellow_tag(self):
		print("Y", end=' ')

CG = Class_Green()
CY = Class_Yellow()

CG.blue_tag()
CY.yellow_tag()
```

What will the output of the following code be?
<pre><code class="language-python">class Class_Blue:
	def blue_tag(self):
		print(&quot;B&quot;, end=' ')

class Class_Orange:
	def orange_tag(self):
		print(&quot;O&quot;, end=' ')

class Class_Green(Class_Orange, Class_Blue):
	def green_tag(self):
		print(&quot;G&quot;, end=' ')

class Class_Yellow(Class_Orange):
	def yellow_tag(self):
		print(&quot;Y&quot;, end=' ')

CG = Class_Green()
CY = Class_Yellow()

CG.blue_tag()
CY.yellow_tag()
</code></pre>

What will the output of the following code be?

```python
class Gold:
	def __init__(self):
		self.my_function(100)

	def my_function(self, num):
		self.num = num / 2

class Silver(Gold):
	def __init__(self):
		super().__init__()
		print("Value:", self.num)

	def my_function(self, num):
		self.num = num / 5

s = Silver()
```

What will the output of the following code be?
<pre><code class="language-python">class Gold:
	def __init__(self):
		self.my_function(100)

	def my_function(self, num):
		self.num = num / 2

class Silver(Gold):
	def __init__(self):
		super().__init__()
		print(&quot;Value:&quot;, self.num)

	def my_function(self, num):
		self.num = num / 5

s = Silver()
</code></pre>

What will the value of `mylist` be at the end of the following code?

```python
mylist = ["Apple", "Ball", [1, 2]]
mylist_new = mylist
mylist_new[1] = "Coffee"
print(mylist)
```

What will the value of <code>mylist</code> be at the end of the following code?
<pre><code class="language-python">mylist = [&quot;Apple&quot;, &quot;Ball&quot;, [1, 2]]
mylist_new = mylist
mylist_new[1] = &quot;Coffee&quot;
print(mylist)
</code></pre>

You can access the overridden method in a subclass by using `super()` as a prefix in the `init` function.

You can access the overridden method in a subclass by using <code>super()</code> as a prefix in the <code>init</code> function.

AttributeError: 'Silver' object has no attribute 'function_a'

What is the following code's output?

```python
class Gold:
	def function_a(self):
		print("AA")

	def function_b(self):
		print("BB")

class Silver(Gold):
	def function_c(self):
		print("CC")

s = Silver()
s.function_a()
```

What is the following code’s output?
<pre><code class="language-python">class Gold:
	def function_a(self):
		print(&quot;AA&quot;)

	def function_b(self):
		print(&quot;BB&quot;)

class Silver(Gold):
	def function_c(self):
		print(&quot;CC&quot;)

s = Silver()
s.function_a()
</code></pre>
