We can get file size in Python using the os module.

File Size in Python

The python os module has stat() function where we can pass the file name as argument. This function returns a tuple structure that contains the file information. We can then get its st_size property to get the file size in bytes.

Here is a simple program to print the file size in bytes and megabytes.

# get file size in python
import them
 
file_name = "/Users/pankaj/abcdef.txt"
 
file_stats = os.stat(file_name)
 
print(file_stats)
print(f'File Size in Bytes is {file_stats.st_size}')
print(f'File Size in MegaBytes is {file_stats.st_size / (1024 * 1024)}')

If you look at the stat() function, we can pass two more arguments: dir_fd and follow_symlinks. However, they are not implemented for Mac OS.

Here is an updated program where I am trying to use the relative path but it’s throwing NotImplementedError.

Here's an updated program, I tried using relative paths, but it throws NotImplementedError.

# get file size in python
import them
 
file_name = "abcdef.txt"
relative_path = os.open("/Users/pankaj", os.O_RDONLY)
 
file_stats = os.stat(file_name, dir_fd=relative_path)

Output:
