How Can I Get a File\'s Size in Python?

Checking File Size in Python

Determining the size of a file is a common task in programming. Python provides several ways to accomplish this, with the most straightforward being the use of the os.path.getsize() function.

Using os.path.getsize()

To get the size of a file in Python using os.path.getsize(), simply pass the file path as an argument to the function. The output will be the file size in bytes.

import os
file_size = os.path.getsize("/path/to/file.mp3")
print(file_size)  # Output: 2071611

Example Output

The following code demonstrates how to use os.path.getsize() to check the size of a file:

import os

# Get the size of a file in bytes
file_size = os.path.getsize("file.txt")

# Print the file size
print("File size:", file_size, "bytes")

If the file "file.txt" is 1000 bytes in size, the output will be:

File size: 1000 bytes

Note:

The size returned by os.path.getsize() is always in bytes. If you need the size in a different unit, such as kilobytes or megabytes, you will need to perform the appropriate conversion.
