Pandas and NumPy require absolute paths when reading or saving files, and there are specific format requirements. Below is an example:

data = pd.read_csv('E:/a/b/data.csv')np.savetxt('E:/a/b/data.csv', data, delimiter=',')

Why Absolute Paths?

  • Absolute paths ensure that the same file can be accessed from any working directory, avoiding confusion or file not found errors.
  • They are particularly useful for cross-platform compatibility, as they do not rely on the current working directory’s relative structure.

File path formatting tips:

  • Use double backslashes (\) in Windows environments, while Unix-based systems use single backslashes (\) or forward slashes (\/).
  • Ensure the file name and directory structure are explicitly defined.

Example usage:

import pandas as pdimport numpy as np# Load datadata = pd.read_csv(r'C:\path\to\file\filename.txt')# Save datanp.savetxt(r'C:\path\to\file\filename.txt', data, delimiter=',')

This formatting ensures consistent file access regardless of the operational environment. Always verify file paths before running scripts to prevent errors.
