Python is already used in the backend of most web applications, but sadly it does not work with web browsers to drive the frontend of those applications. Transcrypt can help by creating more coherent web-based projects, using Python to write both the backend and the frontend.

This course builds on the lessons in Using the Python Transcrypt Transipler for Front-end Coding to implement a complete React and Python web-based project. In each chapter, we will refactor existing code to add new functionality, building up the application as you go. Each chapter ends with a running application that includes all of the features we added up to that specific point.

What is the equivalent expression for `print_it(‘caps’, ‘chicago’)` given the functions below?
```py
def print_low(val):
    print(val.lower())

def print_caps(val):
    print(val.upper())

def print_it(key, val):
     my_dict = {'lower': print_low, 'caps': print_caps}
     my_dict[key](val)
```

What is the equivalent expression for <code>print_it(‘caps’, ‘chicago’)</code> given the functions below?
<pre><code class="language-py">def print_low(val):
 print(val.lower())

def print_caps(val):
 print(val.upper())

def print_it(key, val):
 my_dict = {'lower': print_low, 'caps': print_caps}
 my_dict[key](val)
</code></pre>

```py
{key: val for key, val in my_dict if len(val) > 0}
```

```py
{key: val for key, val in my_dict.items() if len(val) > 0}
```

```py
{key: val for key, val in my_dict.items()} if len(val) > 0
```

```py
{key: val for key, val in my_dict.values() if len(val) > 0}
```
