How to Check the Exact Match Dictionary in Python

The Python language lets you create an internal dictionary for keeping a list of values in a list variable. The dictionary list has a key value and the full-name matching word. You use the key value to call and "match" the key to the full-name value. You use the "lookup" function to do an exact match find on the dictionary list variable.

Instructions

1. Open your preferred Python editor and open the project you want to use to do a dictionary lookup. Open the source code file you want to use.

2. Create the dictionary list. You can create several lists if you need to have more than one dictionary list values. The following code makes a list of colors:

   color_dictionary= {
   'O': 'orange',
   'R': 'red',
   'B': 'blue'
   }

3. Perform a "get_key" lookup to determine the color that matches the color key. For instance, to return "orange" to the Python code, the following code performs a dictionary lookup:

   find = match('O')

4. Write the output to the screen. The following returns the value returned from the lookup function:

   print find
