How to check whether a file is empty or not in python

You can check whether a file is empty or not in Python by using the os.path.getsize() function, which returns the size of a file in bytes. If the size is zero, it means the file is empty. Here's how you can do it:

import os def is_file_empty(file_path): return os.path.getsize(file_path) == 0 # Example usage file_path = 'example.txt' if is_file_empty(file_path): print(f'The file {file_path} is empty.') else: print(f'The file {file_path} is not empty.')

In this code:

  1. We import the os module, which provides functions for interacting with the operating system.

  2. We define a function is_file_empty(file_path) that takes a file path as an argument.

  3. Inside the function, we use os.path.getsize(file_path) to get the size of the file specified by file_path.

  4. We compare the file size to zero, and if it's equal to zero, we return True, indicating that the file is empty; otherwise, we return False.

  5. We demonstrate the usage of this function by checking if a file called 'example.txt' is empty or not.

Remember to replace 'example.txt' with the actual path to the file you want to check. This code will correctly determine whether a file is empty or not based on its size.

Examples

  1. "Python check if file is empty" Description: This query seeks a Python solution to determine whether a file is empty or not. Code:

    def is_file_empty(file_path): return os.path.getsize(file_path) == 0 # Example usage file_path = '/path/to/file.txt' if is_file_empty(file_path): print("File is empty.") else: print("File is not empty.")

  2. "Python detect empty file" Description: This query looks for Python code to detect whether a file is empty or not. Code:

    def detect_empty_file(file_path): return os.stat(file_path).st_size == 0 # Example usage file_path = '/path/to/file.txt' if detect_empty_file(file_path): print("File is empty.") else: print("File is not empty.")

  3. "Python check file emptiness" Description: This query aims to find Python code to check whether a file is empty or contains data. Code:

    def check_file_emptiness(file_path): return os.path.isfile(file_path) and os.path.getsize(file_path) == 0 # Example usage file_path = '/path/to/file.txt' if check_file_emptiness(file_path): print("File is empty.") else: print("File is not empty.")

  4. "Python determine if file is empty" Description: This query seeks a Python method to determine if a file is empty. Code:

    def determine_empty_file(file_path): return os.path.getsize(file_path) == 0 # Example usage file_path = '/path/to/file.txt' if determine_empty_file(file_path): print("File is empty.") else: print("File is not empty.")

  5. "Python check if file has no content" Description: This query aims to find Python code to check if a file has no content, i.e., it is empty. Code:

    def has_no_content(file_path): return os.path.getsize(file_path) == 0 # Example usage file_path = '/path/to/file.txt' if has_no_content(file_path): print("File has no content (empty).") else: print("File has content.")

  6. "Python determine empty file presence" Description: This query looks for a Python method to determine the presence of an empty file. Code:

    def determine_empty_file_presence(file_path): return os.path.getsize(file_path) == 0 # Example usage file_path = '/path/to/file.txt' if determine_empty_file_presence(file_path): print("File is empty.") else: print("File is not empty.")

  7. "Python check if file is devoid of data" Description: This query seeks Python code to check if a file is devoid of any data, indicating it is empty. Code:

    def is_file_devoid_of_data(file_path): return os.stat(file_path).st_size == 0 # Example usage file_path = '/path/to/file.txt' if is_file_devoid_of_data(file_path): print("File is devoid of data (empty).") else: print("File contains data.")

  8. "Python identify empty file" Description: This query looks for a Python function to identify whether a file is empty or not. Code:

    def identify_empty_file(file_path): return os.path.getsize(file_path) == 0 # Example usage file_path = '/path/to/file.txt' if identify_empty_file(file_path): print("File is empty.") else: print("File is not empty.")

  9. "Python check if file lacks content" Description: This query seeks Python code to check if a file lacks content, indicating it is empty. Code:

    def lacks_file_content(file_path): return os.path.getsize(file_path) == 0 # Example usage file_path = '/path/to/file.txt' if lacks_file_content(file_path): print("File lacks content (empty).") else: print("File contains data.")

  10. "Python find out if file is empty" Description: This query aims to find Python code to determine if a file is empty or not. Code:

    def is_file_empty(file_path): return os.path.getsize(file_path) == 0 # Example usage file_path = '/path/to/file.txt' if is_file_empty(file_path): print("File is empty.") else: print("File is not empty.")
