Program to flatten a nested list in Python

The python program to flatten a nested list is as follows:

 

# Owner : TutorialsInhand Author : Devjeet Roy

import pandas as pd
nested_list = [22,11,[34,[56,78]],61,[35,91,77,59]]

print("The new list:",list(pd.core.common.flatten(nested_list)))
        

The output of the python program to flatten a nested list is as follows:

 

PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py
The new list: [22, 11, 34, 56, 78, 61, 35, 91, 77

Few important tips about the program

1. To run this program, we will need to have pandas library installed into our system. If it is not, in the terminal type:

"pip install pandas" and wait.

2. The flatten() method in the pandas.core.common package flattens a list, irrespective of its dimensionality.
