In this tutorial, I going to explain the basics of python dictionary operations and methods. <\/p>\n\n\n\n
INTRODUCTION<\/h4>\n\n\n\n
Python dictionary is an unordered collection of items and also it contains key-value pairs and enclosed by curly-braces { }.<\/p>\n\n\n\n
Each key-value pair in a python dictionary is separated by a colon(:) and each key is separated by a \u2018comma\u2019.<\/p>\n\n\n\n
Most importantly python dictionary, keys should not be repeated and values can be any datatype.<\/p>\n\n\n\n
<\/p>\n\n\n\n
Create an empty dictionary: <\/strong><\/h4>\n\n\n\n First of all we can create the dictionary using the variable name for that we can use empty curly-braces. It will create an empty dictionary in python.<\/p>\n\n\n\n

<\/figure><\/li><\/ul>\n\n\n\nCreate a dictionary with the<\/strong> element<\/strong>:<\/h4>\n\n\n\n we can add items inside curly braces {} and separated by a comma for creating a dictionary with element.<\/p>\n\n\n\n

<\/figure><\/li><\/ul>\n\n\n\nAccess elements from the dictionary<\/strong>:<\/h4>\n\n\n\nWe can access the dictionary elements using the key.<\/p>\n\n\n\n

<\/figure><\/li><\/ul>\n\n\n\nUpdate dictionary value:<\/strong><\/h4>\n\n\n\nWe can add new items into the dictionary and also we can update the existing item.<\/p>\n\n\n\n

<\/figure><\/li><\/ul>\n\n\n\nAdd element into the dictionary:<\/strong><\/h4>\n\n\n\nWe can add the new element into the existing dictionary with the new key-value pair.<\/p>\n\n\n\n

<\/figure><\/li><\/ul>\n\n\n\nRemove element from the dictionary:<\/strong><\/h4>\n\n\n\nWe can remove the element from the dictionary using the pop() method, for that, we can give key name within the pop method.<\/p>\n\n\n\n
<\/p>\n\n\n\n

<\/figure><\/li><\/ul>\n\n\n\nRemove all item from the dictionary:<\/strong><\/h4>\n\n\n\nWe can use clear() method to remove all element from the dictionary. It will display the empty dictionary.<\/p>\n\n\n\n

<\/figure><\/li><\/ul>\n\n\n\nDelete dictionary<\/strong>:<\/h4>\n\n\n\nWe can use the del<\/strong> method to delete the full dictionary.<\/p>\n\n\n\n![\"\"](\"https:\/\/blog.pheonixsolutions.com\/wp-content\/uploads\/2019\/09\/dict8.png\")
