![]() That is why when you print the “No_of_ems()” command, it prints (“Orange”: 196) pair. ![]() Here, key ‘orange’ is repeated therefore ems() will overwrite the value 150 by 196. The keys should be different otherwise the program will overwrite the previous value as shown in the above output window. Lets consider an example in which the ‘key’ and ‘value’ variables iterate over the dictionary. We can iterate over these tuples to access these key and value pairs. The function ems() returns the object items in the form of a (key, value) tuple. method 1: using for loop to get no of keys in dictionary Method 2: Use len() function to count and print keys.Method 1: Get number of keys in a Dictionary using for loop.In this article, we will discuss the following methods along with examples in detail Then, using for loop, traverse over the dictionary items. Another method is to declare and initialize a variable which holds the count of iterations. The len() function provides the length of items in a dictionary and thus providing the total number of keys. Using len() function or for loop, we can count the number of keys in a dictionary in python. ![]() ![]() If you want to learn more about Python Tutorials, See this. This tutorial covers different methods by which we can count the number of keys in a dictionary in python.īefore moving towards this article, you should have a basic understanding of dictionaries, how they are created, their syntax and uses, etc. Dictionaries are very useful data structures in python that can hold a collection of items in the form of a key-value pair. ![]()
