36. Series to DataFrame

Write a Pandas program to convert given series into a dataframe with its index as another column on the dataframe.

Sample Solution :

Python Code :

import numpy as np
import pandas as pd
char_list = list('ABCDEFGHIJKLMNOP')
num_arra = np.arange(8)
num_dict = dict(zip(char_list, num_arra))
num_ser = pd.Series(num_dict)
df = num_ser.to_frame().reset_index()
print(df.head())

Sample Output:

  index  0
0     A  0
1     B  1
2     C  2
3     D  3
4     E  4

Explanation:

char_list = list('ABCDEFGHIJKLMNOP'): This code creates a list of characters called char_list. It contains the 16 uppercase letters from A to P. Each character in the list is a string of length 1. The list() function is used to convert the string of characters into a list of individual characters.

num_arra = np.arange(8): This code creates a NumPy array 'num_arra' containing the integers from 0 to 7 using the np.arange() function.

num_dict = dict(zip(char_list, num_arra)): This code creates a dictionary 'num_dict' using the dict() function and the zip() function.

num_ser = pd.Series(num_dict): This code creates a Pandas Series 'num_ser' using the pd.Series() function and the dictionary 'num_dict' created in the previous line of code.

df = num_ser.to_frame().reset_index(): This code converts the Pandas Series 'num_ser' to a Pandas DataFrame using the to_frame() method, which returns a DataFrame with the Series values as a single column and the Series index as the index of the DataFrame.
