Python write bytes to file

  • by

In Python, you can write bytes to a file using the built-in open() function in binary mode, and then use the write() method to write the bytes to the file.

To write bytes to a file in Python, you need to follow these steps:

  1. Open the file in binary write mode using the open() function with the mode 'wb'.
  2. Write the bytes data to the file using the write() method.
  3. Close the file to ensure proper file handling.

In Python, writing bytes to a file means saving binary data, represented as bytes, into a file on your computer’s filesystem. The data can be anything that can be represented as bytes, such as images, audio, video, compressed files, or any other binary data.

Python writes bytes to a file

Here’s a complete example of how to write bytes to a file in Python:

# Example bytes data (you can replace this with your actual bytes data)
bytes_data = b'\x48\x65\x6c\x6c\x6f\x20\x57\x6f\x72\x6c\x64'  # Bytes representation of "Hello World"

# Specify the file path where you want to write the bytes
file_path = 'example.bin'

# Open the file in binary write mode ('wb')
with open(file_path, 'wb') as file:
    # Write the bytes data to the file
    file.write(bytes_data)

# Confirm that the bytes have been written to the file
print(f"Bytes have been written to {file_path}")

Output:

Python write bytes to file

In this example, the bytes_data variable contains the bytes representation of the string “Hello World”. When you run this code, it will create a file named example.bin in the current working directory and write the bytes to it. The output will confirm that the bytes have been successfully written to the file.
