Unlock the Power of Python Dictionaries: Sorting Made Easy
Sorting by Values: The Lambda Way
When working with Python dictionaries, sorting becomes a crucial task to extract valuable insights from your data. One way to sort a dictionary is 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.
dt = {'apple': 5, 'banana': 7, 'cherry': 3}
sorted_dt = sorted(dt.items(), key=lambda item: item[1])
print(sorted_dt)The output will be:
[('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! You can 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.
dt = {'apple': 5, 'banana': 7, 'cherry': 3}
sorted_values = sorted(dt.values())
print(sorted_values)The output will be:
