Write a NumPy program to convert Pandas dataframe to Numpy array with headers
import numpy as np import pandas as pd np_array = np.random.rand(12,3) print("Original Numpy array:") print(np_array) print("Type: ",type(np_array)) df = pd.DataFrame(np.random.rand(12,3),columns=['A','B','C']) print("\nPanda's DataFrame: ") print(df) print("Type: ",type(df))
Sample Output:
