2) Loop through a dictionary to print the values only To print the values only of a dictionary, we use thevalues()method. When we loop through a dictionary using thevalues()method – it returns the values of the dictionary one by one. ...
How to Loop Through a Dictionary in Python? Before diving into iteration methods, let’s briefly recap dictionaries in Python. A dictionary is an unordered collection of key-value pairs. Each key must be unique, and it maps to a specific value. Dictionaries are defined using curly braces{},...
Loop through sequences: used for iterating over lists, strings, tuples, dictionaries, etc., and perform various operations on it, based on the conditions specified by the user. Example: Calculate the average of list of numbers numbers = [10, 20, 30, 40, 50] # definite iteration # run...
In the above code, we create an empty dictionarymy_dict, then loop through the listmy_listApplying theenumerate()function. Theenumerate()functionreturns a tuple incorporating the value and index of every individual element in the list. We use the index as the key and the value as the value...

Dictionaries in Python In this quiz, you'll test your understanding of Python's dict data type. By working through this quiz, you'll revisit how to create and manipulate dictionaries, how to use Python's operators and built-in functions with them, and how they're implemented for efficient...
In Python, we use a for loop to iterate over various sequences, such as lists, tuples, sets, strings, or dictionaries. The for loop allows you to iterate through each element of a sequence and perform certain operations on it. In this tutorial, we will e
This method should return a new iterator object, which allows you to iterate through all the items in the underlying container type.For Python dictionaries, .__iter__() allows direct iteration over the keys by default. This means that if you use a dictionary directly in a for loop, Python...
Method 7: Using A For Loop Add key-value pairs to a nested list and loop through the list to add multiple items to a dictionary. For example: my_dictionary = { "one": 1, "two": 2 } my_list = [["three", 3], ["four", 4]] ...
# loop through a dictionary for key, value in my_dict.items(): print(key, value) Copy This will output the following: apple 3 banana 5 pear 4 Conclusion: In this comprehensive guide, we have covered everything you need to know about dictionaries in Python, including how to create them...
