How to use pandas DataFrame In Python
By using pandas dataframe we will convert list of dict to dict of list
Syntax: pandas.DataFrame(list_of_dictionary).to_dict(orient=”list”)
Where:
- list_of_dictionary is the input
- to_dict() method is to convert into dictionary
- orient parameter is to convert into list
Example:
Python3
#import pandasimport pandas as pd# consider the list of dictionarydata = [{'manoj': 'java', 'bobby': 'python'}, {'manoj': 'php', 'bobby': 'java'}, {'manoj': 'cloud', 'bobby': 'big-data'}]# convert into dictionary of list# with list as values using pandas dataframepd.DataFrame(data).to_dict(orient="list") |
Output:
{‘bobby’: [‘python’, ‘java’, ‘big-data’], ‘manoj’: [‘java’, ‘php’, ‘cloud’]}
Time Complexity: O(n), where n is the length of the given list of dictionary
Auxiliary Space: O(n)
