Read data from a CSV file into a Pandas DataFrame and convert to NumPy array
NumPy: I/O Operations Exercise-15 with Solution
Write a NumPy program that reads data from a CSV file into a Pandas DataFrame and then converts it to a NumPy array.
Sample Solution:
Python Code:
import pandas as pd
import numpy as np
# Define the path to the CSV file
csv_file_path = 'data.csv'
# Read the CSV file into a Pandas DataFrame
df = pd.read_csv(csv_file_path)
# Convert the DataFrame to a NumPy array
data_array = df.to_numpy()
# Print the DataFrame and the NumPy array
print("Pandas DataFrame:")
print(df)
print("\nNumPy Array:")
print(data_array)
Output:
Pandas DataFrame: 10 Shaun Hephzibah 95 0 11 Zayden Jeremiah 90 1 12 Luna Marciano 85 2 13 Kord Shanene 96 3 14 Coeus Zorana 95 NumPy Array: [[11 'Zayden Jeremiah' 90] [12 'Luna Marciano' 85] [13 'Kord Shanene' 96] [14 'Coeus Zorana' 95]]
Explanation:
- Import Pandas and NumPy Libraries: Import the Pandas and NumPy libraries to handle DataFrames and arrays.
- Define CSV File Path: Specify the path to the CSV file containing the data.
- Read CSV File into DataFrame: Use pd.read_csv() to read the contents of the CSV file into a Pandas DataFrame.
- Convert DataFrame to NumPy Array: Use the to_numpy() method of the DataFrame to convert it into a NumPy array.
- Print DataFrame and NumPy Array: Output both the DataFrame and the resulting NumPy array to verify the data has been read and converted correctly.
