Title: Parsing Query Strings in Python: A Comprehensive Tutorial
Introduction:
Let's start with a basic example. Suppose you have the following query string:
Use the parse_qs function to parse this query string into a dictionary.
The output will be a dictionary where keys are parameter names, and values are lists of parameter values.
Now that you have a dictionary with the parsed values, you can access individual parameters.
If a parameter can have multiple values, parse_qs returns a list for that parameter.
Query strings may contain URL-encoded values. Use the unquote function to decode these values.

Step 2: Create a Sample Query String
Let's start by creating a sample query string that we'll use for demonstration purposes.
Step 3: Parse the Query String
Use the parse_qs function to parse the query string into a dictionary.
Step 4: Accessing Values from the Parsed Query String
Now, you can access individual values using the keys of the dictionary.
Step 5: Handling Multiple Values for a Key
If a key in the query string has multiple values, parse_qs returns a list for that key.
Step 6: Handling Missing Keys
It's good practice to check if a key exists before trying to access its value to avoid potential errors.
Step 7: Putting It All Together
