How to Determine If a File is Empty
Often, it is necessary to verify whether a file contains any data. Python provides efficient ways to perform this check.
Checking File Size
One simple method to check if a file is empty is to examine its file size. A file with a size of zero bytes is considered empty. The os.stat() function can be used to obtain the file's size.
In the provided example, we import the os module and use os.stat() to retrieve the file stat object. We then access the st_size attribute of the stat object to retrieve the file size. If the file size is zero, as in our example, the file is indeed empty and the condition os.stat("file").st_size == 0 will evaluate to True.
This technique is straightforward and suitable for smaller files. However, for larger files, it may involve unnecessary loading of the entire file into memory, potentially affecting performance.
