Get dict key by max value in python

Get dict key by max value in python

To get the key associated with the maximum value in a dictionary in Python, you can use the max function with a custom key function that compares values. Here's an example:

my_dict = {'apple': 3, 'banana': 5, 'cherry': 1, 'date': 5} # Find the key with the maximum value max_key = max(my_dict, key=lambda k: my_dict[k]) print(f"The key with the maximum value is '{max_key}' with a value of {my_dict[max_key]}.")

In this example, we use the max function with a custom key function that takes each key k from the dictionary and compares the corresponding values my_dict[k]. This will return the key with the maximum value.

When you run this code, it will output:

The key with the maximum value is 'banana' with a value of 5.

So, the key 'banana' has the maximum value of 5 in the my_dict dictionary.
