Unlock the Power of Python Dictionaries: Sorting Made Easy
When working with Python dictionaries, sorting becomes a crucial task to extract valuable insights from your data. But, did you know that sorting dictionaries can be a bit tricky? Fear not, as we’re about to demystify the process and take your Python skills to the next level!
Sorting by Values: The Lambda Way
In our first example, we’ll sort a dictionary based on its values using the lambda function. This powerful tool allows us to extract the values from each key-value pair and feed them into the sorted() function. The magic happens when we use key=lambda item: item[1], which returns the values of each pair. The sorted() function then takes these values and sorts them in ascending order.
The Result: A Sorted Dictionary
Here’s the output:
dt = {'apple': 5, 'banana': 7, 'cherry': 3}
sorted_dt = sorted(dt.items(), key=lambda item: item[1])
print(sorted_dt)
Output:
[('cherry', 3), ('apple', 5), ('banana', 7)]
Sorting Values Only: A Simpler Approach
What if you only want to sort the values of your dictionary? No problem! In our second example, we’ll use the sorted() function with dt.values() to achieve just that. This approach is straightforward and efficient, giving you the sorted values in no time.
The Code:
dt = {'apple': 5, 'banana': 7, 'cherry': 3}
sorted_values = sorted(dt.values())
print(sorted_values)
Output:
[3, 5, 7]
