Iterating over dictionaries using ‘for’ loops is a process that can be used to traverse through the key-value pairs contained in a dictionary.
This can be useful for performing operations on each pair, or for extracting specific information from the dictionary.
In this guide, we will discuss how to iterate over dictionaries using ‘for’ loops in Python and provide some examples of how it can be done.
Iterating over dictionaries using ‘for’ loops: A detailed guide
When iterating over a dictionary using a ‘for’ loop, the variable that you use will represent each key-value pair in the dictionary.
In order to access the keys and values from this variable, you can use the methods dict.items() and dict.keys(), respectively.
The syntax for this is as follows:
# python with Wholeblogs for key, value in dict.items(): # do something with the key and value or # python with Wholeblogs for key in dict.keys(): # do something with just the keys
