title: python tutorial - iterating a dictionary sorted by values
introduction:
in python, dictionaries are unordered collections of items. however, there might be scenarios where you need to iterate through a dictionary based on its values in a sorted order. this tutorial will guide you through the process of iterating a python dictionary sorted by values, along with code examples.
step 1: create a sample dictionary
let's start by creating a sample dictionary for demonstration purposes.
step 2: sorting the dictionary by values
to iterate the dictionary sorted by values, you need to convert the dictionary items into a list of tuples and then use the sorted() function. the key parameter of the sorted() function is used to specify the sorting criterion, which, in this case, is the second element of each tuple (the values).
step 3: iterate through the sorted dictionary
now that we have a sorted list of tuples, we can iterate through it using a simple for loop.
putting it all together:
here's the complete code:
output:
conclusion:
this tutorial has demonstrated how to iterate through a python dictionary sorted by values. sorting the dictionary items as tuples and then using a loop to iterate through the sorted items allows you to achieve the desired order based on values. this technique can be useful in various scenarios where a sorted representation of a dictionary is required.
