This highly interactive and advanced course will give you insight into the most common Python tricks and tips. This course is for practicing Python programmers who are aiming for proficiency in Python 3. If you want to switch from Python 2 to Python 3, this is your go-to course. 

This course will help you learn the Pythonic Way of writing code and leveraging advanced robust features to become more proficient than the average developer. You’ll start by covering Python’s built-in data structures, and then you’ll move on to different programming paradigms like functional programming and object-oriented programming. 

In the latter half of the course, you’ll focus on iterables, generators, and coroutines. You’ll also have the opportunity to work on two projects to help strengthen what you learn. In all, this course is perfect for anyone who wants to become a confident and competent Pythonista by picking up the idioms and practical tips.

Mastering the Art of Programming in Python 3

It will generate an error, as tuples are _immutable_ datatypes.

Deduce the output of the following program.
```python3
tuple1 = ('a', 'b', [1, 2])
tuple2 = ('a', 'b', [1, 2])
print(tuple1 == tuple2)
tuple1[-1].append(3)
print(tuple1 == tuple2)
```

Deduce the output of the following program.
<pre><code class="language-python3">tuple1 = ('a', 'b', [1, 2])
tuple2 = ('a', 'b', [1, 2])
print(tuple1 == tuple2)
tuple1[-1].append(3)
print(tuple1 == tuple2)
</code></pre>

Deduce the output of the following program.
```python3
l1 = [1, 2, 3]
l2 = list(l1)

l1[0] = 4
print(l2)
```

Deduce the output of the following program.
<pre><code class="language-python3">l1 = [1, 2, 3]
l2 = list(l1)

l1[0] = 4
print(l2)
</code></pre>

An `is` expression evaluates to `True` if two variables point to the same (identical) object.

An `==` expression evaluates to `True` if the objects referred to by the variables are equal (have the same contents).

If `a == b` evaluates to `True`, then `a is b` will always be `True`.

If `a is b` evaluates to `False`, then `a == b` can be `True`.

Deduce the output of the following program.
```python3
class CountedObject:
  num_instances = 0
  def __init__(self): 
    self.num_instances += 1

print(CountedObject.num_instances)
print(CountedObject().num_instances)
print(CountedObject().num_instances)
print(CountedObject().num_instances)
print(CountedObject.num_instances)
```

Deduce the output of the following program.
<pre><code class="language-python3">class CountedObject:
 num_instances = 0
 def __init__(self): 
 self.num_instances += 1

print(CountedObject.num_instances)
print(CountedObject().num_instances)
print(CountedObject().num_instances)
print(CountedObject().num_instances)
print(CountedObject.num_instances)
</code></pre>

 A(n) _______ method can modify class state.
