This beginner course covers essential Python programming concepts, laying the groundwork for more specialized courses on domain-specific Python libraries.

Python is an important programming language used in data science, machine learning, web scraping, and web application development, making it essential for modern developers.
This course starts with teaching fundamental programming concepts in Python 3, including conditional execution, repetition, and functions, before moving on to advanced topics like data structures and object-oriented programming. Quizzes and hands-on coding challenges along the way help reinforce what you have learned.

By the end of this course, you will have a solid foundation in Python programming, enabling you to write clean and efficient code and tackle more advanced topics and projects with confidence.

Learn Intermediate Python 3

Have a look at the `for` loop below:

```python
string_list = ["Anakin", "Luke", "Rey", "Leia", "Vader"]
for s in string_list:
 if len(s) < 5:
 print(len(s))
```
What will be the output on the terminal at the end of the loop?

Have a look at the <code>for</code> loop below:
<pre><code class="language-python">string_list = [&quot;Anakin&quot;, &quot;Luke&quot;, &quot;Rey&quot;, &quot;Leia&quot;, &quot;Vader&quot;]
for s in string_list:
 if len(s) &lt; 5:
 print(len(s))
</code></pre>
What will be the output on the terminal at the end of the loop?

```python
string_list = ["Anakin", "Luke", "Rey", "Leia", "Vader"]
i = 0
while i < len(string_list):
 if len(string_list[i]) < 5:
 print(len(string_list[i])) 
```

```python
string_list = ["Anakin", "Luke", "Rey", "Leia", "Vader"]
i = 0
while i < len(string_list):
 if len(string_list[i]) < 5:
 print(len(string_list[i]))
 i += 1
```

```python
string_list = ["Anakin", "Luke", "Rey", "Leia", "Vader"]
i = 0
while i < len(string_list):
 if len(string_list[i]) < 5:
 print(len(string_list[i]))
 i += 1 
```

```python
string_list = ["Anakin", "Luke", "Rey", "Leia", "Vader"]
i = 0
while i < len(string_list):
 i += 1
 if len(string_list[i]) < 5:
 print(len(string_list[i])) 
```

In the following code, how would we replace the `for` loop with a `while` loop?

```python
string_list = ["Anakin", "Luke", "Rey", "Leia", "Vader"]
for s in string_list:
 if len(s) < 5:
 print(len(s))
```

In the following code, how would we replace the <code>for</code> loop with a <code>while</code> loop?
<pre><code class="language-python">string_list = [&quot;Anakin&quot;, &quot;Luke&quot;, &quot;Rey&quot;, &quot;Leia&quot;, &quot;Vader&quot;]
for s in string_list:
 if len(s) &lt; 5:
 print(len(s))
</code></pre>

**(True or False)** A `while` loop runs as long as its condition holds `True`.

(True or False) A <code>while</code> loop runs as long as its condition holds <code>True</code>.

It only skips an iteration in a `while` loop.

What is the purpose of the `break` statement?

What is the purpose of the <code>break</code> statement?
