If you’re a Python developer, then you know how important it is to handle files using Python. One of the essential tasks is to get the file size, which can sometimes be challenging. Fear not, as this article is here to provide you with useful tips on how you can retrieve the file size in Python.
Why Knowing File Size is Important
Knowing the size of a file is crucial in several situations. It may help you plan for storage capacity or determine if the file can be transmitted over a given network. Some applications only support specific file sizes, so it’s important to keep this information in mind during the development process.
Ways to Get File Size in Python
There are various ways to get the file size in Python, and we’ll dive into these different methods one by one.
Method 1: Using os.path.getsize()
The standard way to get the file size in Python is by using the os.path.getsize() function. This function returns the size of a file in bytes. Here’s a sample code:
import osfile_size = os.path.getsize(myfile.txt)print(file_size)
The code above will print the size of myfile.txt in bytes.
Method 2: Using os.stat()
You can also use the os.stat() function to retrieve the file size. This function provides more information about the file, such as its creation and modification dates. Here’s an example of how to use it:
import osfile_stat = os.stat(myfile.txt)print(file_stat.st_size)
The code will print the size of myfile.txt in bytes.
Comparing os.path.getsize() and os.stat()
The os.path.getsize() function and the os.stat() function both provide the file size, but they have some differences. The os.path.getsize() function is faster and more efficient than the os.stat() function for getting the file size. However, the os.stat() function returns more information about the file that may be useful.
|os.path.getsize()||Fast||File size in bytes|
|os.stat()||Slower||File size and additional information (creation/modification date, permissions, etc.)|
Tips for Efficient File Size Retrieval
Retrieving the file size can take some time, depending on the size of the file or the number of files you’re handling. Here are some tips to help make the process more efficient:
- Only retrieve the file size when you need it. Avoid calling the os.path.getsize() or os.stat() function unnecessarily.
- If you need to handle multiple files, use a loop to retrieve the file sizes.
- Avoid using the os.walk() function if you only need to retrieve the file size. This function can be slow if you’re processing many files.
- If you need to work with very large files, consider using a buffered approach instead of reading the entire file into memory.
Knowing how to retrieve the file size is an essential skill for any Python developer who works with files. Using the os.path.getsize() or os.stat() functions will give you the file size you need, and these functions are easy to use. Remember, if you’re working with many files, be sure to use efficient techniques to retrieve the file sizes to avoid slowing down your program.
Thank you for visiting our blog and reading our latest post about Python tips. We hope that our article on getting file size in Python has been helpful to you. As we come to a close, we’d like to highlight some key takeaways from this post.
First, we learned that there are multiple ways to get the file size in Python, but the most efficient method is by using the built-in os module. By importing this module and using the os.path.getsize() function, we can easily obtain the size of any file in our system.
Secondly, we also discussed some common errors that developers encounter when working with file sizes, such as data type conflicts and incorrect file paths. Addressing these issues beforehand can save you time and prevent unwanted errors in your code.
Lastly, we encourage you to explore more Python tips and tricks to improve your programming skills. The Python programming language is constantly evolving, and staying up-to-date with its latest features and functionalities can open up many new opportunities for your projects and career.

The easiest way to get file size in Python is to use the os module’s stat() method. You can do this by calling os.stat(filepath).st_size. This will return the size of the file in bytes.
To get the file size in megabytes, you need to divide the size in bytes by 1,048,576. You can use the following code to achieve this:
import osfilesize = os.path.getsize(myfile.txt)filesize_in_mb = filesize / (1024 * 1024)print(filesize_in_mb)
Yes, you can get the file size in gigabytes by dividing the size in bytes by 1,073,741,824. Here’s an example:
import osfilesize = os.path.getsize(myfile.txt)filesize_in_gb = filesize / (1024 * 1024 * 1024)print(filesize_in_gb)
You can use the following function to get the file size in a human-readable format:
import osdef convert_bytes(num): for x in ['bytes', 'KB', 'MB', 'GB', 'TB']: if num < 1024.0: return %3.1f %s % (num, x) num /= 1024.0print(convert_bytes(os.path.getsize(myfile.txt)))
