Python Iterate Dictionary Key, Value

In this article we will show you the solution of python iterate dictionary key, value, Python dictionary also known as dict is a significant data structure that's operated to keep fundamentals in key- value pairs.

Each entryway in the dictionary is in the configuration of key- value pairs. A dictionary is a collection of fundamentals that's unordered, changeable, and doesn't permit duplicates in keys.

Dictionary values should exist boxed with{} and key value pair severed by commas. The dictionaries are listed by keys.

Another major characteristic of dictionaries is that they're changeable data types, therefore, that you can exist appended, deleted, and updated their key- value pairs from the dictionary.

Step By Step Guide On Python Iterate Dictionary Key, Value :-

Dictionary Key – As I adverted previously, Dictionary doesn’t permit copied keys and keys must exist of unchangeable type (similar as string, number, tuple).

In case, you append duplicates, it overrides the being keys of the dictionary.

Dictionary Value – The values can exist of any type of object and can exist permitted duplicates. To pick up a value from a Python Dictionary you hold to repeat over keys.

Dictionary in Python is an unordered library of data values, utilized to store data values like a chart, unlike distinct Data Types that hold simply a single value as an component, Dictionary holds the key value pair.

There are many ways to iterate over a dictionary by Python.

  • Access key using the build. keys()
  • Access key without using a key()
  • Iterate through all values using. values()
  • Iterate through all key, and value pairs utilizing items()
  • Access both key and value without utilizing items()
  • Print items in Key- Value in pair

Method 1 Access key utilizing the build. keys():

In this method, you'll know that we're utilizing an in- build. keys() technique which helps us to publish all the keys in the dictionary.

Method 2 Access key without using a key():

Repeating over dictionaries utilizing ‘ for ’ loops for repeating our keys and publishing all the keys present in the Dictionary.

Method 3 Iterate through all values utilizing. values():

In this method, we're utilizing the values() system to publish all the values carry in the dictionary.

Method 4 Iterate through all key, and value pairs using items():

In this method, we're publishing all the key and value pairs present in a dictionary utilizing a items() system.

Method 5 Access both key and value without using items():

In this method, we're utilizing a Python Loop Through a Dictionary, and with each replication, we're carrying the key of the directory after that, we're publishing key data and we're utilizing a key as an indicator to print values from the directory.

Method 6 Print items in Key- Value in pair:

In this method, we're publishing the key values data in the form of pairs and all the pair are boxed in a dictionary.

Method 7 Access key using unloading of dict:

In this method, you'll know that we're utilizing * to unload the dict. The * dict method which helps us to unload all the keys in the dictionary.

namesAndSurnames = {
    'Salman': 'Khan',
    'Ranbir': 'Kapoor',
    'Deepika': 'Padukone',
    'Bhavin': 'Bhanushali'
}
print('List of given names:\n')
for names in namesAndSurnames:
    print(names)
  1. In the first line of code we create dictionary named as namesAndSurnames.
  2. In that dictionary we create some key value pairs.
  3. After that we create the print function.
  4. Then we iterate dictionary by using for loop to get the keys.

Conclusion :-

Hence, we have successfully learnt how to iterate dictionary key, value in python.

I hope this article on python iterate dictionary key, value helps you and the steps and method mentioned above are easy to follow and implement.
