Python newest file in a directory

newest = max(file , key = os.path.getctime) 

This is iterating over the characters in your filename instead of your list of files.

You are doing something like max(«usdfdsf.xls», key = os.path.getctime) instead of max([«usdfdsf.xls», . ], key = os.path.getctime)

You probably want something like

files = [x for x in os.listdir('E:\\Downloads') if x.endswith(".xls")] newest = max(files , key = os.path.getctime) print "Recently modified Docs",newest 

You may want to also improve the script so that it works if you’re not in the Downloads directory:

files = [os.path.join('E:\\Downloads', x) for x in os.listdir('E:\\Downloads') if x.endswith(".xls")] 

You can use glob to get a list of xls files.

import os import glob files = glob.glob('E:\\Downloads\\*.xls') print("Recently modified Docs", max(files , key=os.path.getctime)) 

If you prefer the more up-to-date pathlib solution, here it is:

from pathlib import Path XLSX_DIR = Path('../../somedir/') XLSX_PATTERN = r'someprefix*.xlsx' latest_file = max(XLSX_DIR.glob(XLSX_PATTERN), key=lambda f: f.stat().st_ctime) 

Python select last 12 hours new generated files in a folder, os.path.getmtime(path) gives you the modification time for that file. – Tim Roberts. Jul 26, 2021 at 6

Finding latest file in a folder using python

It should be ok if the list is not empty, but it seems to be. So first check if the list isn’t empty by printing it or something similar.

I tested this code and it worked fine:

import os import glob mypath = "C:/Users//Downloads/*.*" print(min(glob.glob(mypath), key=os.path.getmtime)) print(max(glob.glob(mypath), key=os.path.getmtime)) 

glob.glob has a limitation of not matching the files that start with a .

So, if you want to match these files, this is what you should do — (assume a directory having .picture.png in it)

import glob glob.glob('.p*') #assuming you're already in the directory 

Also, it would be an ideal way to check the number of files present in the directory, before operating on them.

How to get the latest file from folder using python, Use import glob import os files = glob.glob(‘/path/to/folder/*’) latest_file = max(files, key=os.path.getctime) print(latest_file).

Get second newest file in a folder

Looks like you actually want getmtime , not getctime (since you’re showing us a screenshot showing modification times).

sorted_files = sorted(list_of_files, key=os.path.getmtime) print sorted_files[-2] 

Hmm, here are a couple ways to possible go about it.

1. Reverse the sort. Sort it in the other direction and try accessing sorted_list[0] and sorted_list[1] . Maybe that will give you a more promising result
2. Access file in the list and sort yourself. You could loop through the list, run os.path.getctime on them, and use that data to find the recent and second most recent items yourself.
3. Continue to google or wait on another answer. Or use getmtime as Stefan mentioned.

Python Script to Get the Newest File in a Directory — Tips and Best Practices

Learn how to use Python to get the newest file in a directory with code examples and best practices. Get tips on working with CSV files, sorting files by date and time, and using context managers.

As technology continues to evolve, businesses and organizations are finding it increasingly important to manage their files in an efficient and organized manner. Python, a popular programming language , is a great tool to help manage files and directories. In this article, we will explore how to use Python to get the newest file in a directory.

Introduction

When managing files, it can be difficult to keep track of the latest version of a file. This is where Python comes in handy. With Python, you can easily write a script to get the newest file in a directory, which will save you time and effort. In this post, we will cover the following topics:

• Listing the newest file ending with .xls in a Python script
• Importing a CSV file using the os module
• Returning the name of the latest file in a folder
• Getting the list of all files and directories in a specified directory
• Additional methods and best practices for working with files

By the end of this post, you will have a good understanding of how to use Python to get the newest file in a directory and also learn some best practices for working with files .

Listing the newest file ending with .xls in a Python script

If you have a directory with multiple files and you need to get the newest file ending with .xls, you can use Python to make it easy. To accomplish this, we will use the max() function with the os.path.getctime key to get the newest file. Here is the code example:

import ospath = '/path/to/directory' newest_file = max([f for f in os.listdir(path) if f.endswith('.xls')], key=os.path.getctime) print(newest_file) 

In this example, we first specify the directory path. Then, we use a list comprehension to get all the files ending with .xls in the specified directory. Finally, we use the max() function with the os.path.getctime key to get the newest file.

Importing a CSV file using the os module

If you need to import a CSV file, you can use the os module to accomplish this. However, it is important to have Pandas installed to work with CSV files. Here is the code example:

import os import pandas as pdpath = '/path/to/file.csv' df = pd.read_csv(os.path.abspath(path)) print(df.head()) 

In this example, we first specify the path to the CSV file. Then, we use the os.path.abspath method to get the absolute path of the file. Finally, we use the pd.read_csv method to import the CSV file into a Pandas DataFrame.

Returning the name of the latest file in a folder

To return the name of the latest file in a folder, we can use the iterdir() method to get all files and directories in a specified path. Then, we can use the os.path.getctime method to get the creation time of a file. Here is the code example:

import ospath = '/path/to/directory' latest_file = max(os.scandir(path), key=lambda entry: entry.stat().st_ctime) print(latest_file.name) 

In this example, we first specify the directory path. Then, we use the os.scandir method to get all files and directories in the specified directory. Finally, we use the max() function with a lambda function that returns the creation time of the file using the entry.stat().st_ctime method.

Getting the list of all files and directories in a specified directory

To get the list of all files and directories in a specified directory, we can use the os.listdir() method. Additionally, we can use the os.path.splitext method to split a filename and extension. Finally, we can use the sorted() function to sort files by date and time. Here is the code example:

import ospath = '/path/to/directory' files = [os.path.join(path, f) for f in os.listdir(path) if os.path.splitext(f)[1] == '.txt'] files.sort(key=lambda x: os.path.getmtime(x)) print(files) 

In this example, we first specify the directory path. Then, we use a list comprehension to get all files ending with .txt in the specified directory. We also use the os.path.splitext method to split the filename and extension. Finally, we use the sorted() function with a lambda function that returns the modification time of the file using the os.path.getmtime method.

Additional methods and best practices for working with files

There are many additional methods and best practices for working with files in Python. For example, the glob module can be used to get all files with a certain extension. The os.path.getmtime method can be used to get the modification time of a file, while the os.path.getatime method can be used to get the access time of a file. Additionally, the os.path.join method can be used to join a directory and filename. It is important to use the datetime module to convert timestamps to dates . Finally, it is important to close files after use and handle errors appropriately. Here are some tips and tricks for working with files:

• Use context managers to ensure files are closed properly
• Use relative paths when possible to avoid hardcoding paths
• Use descriptive filenames to make it easy to find files later

Other code examples for getting the newest file in a directory using Python

In Python , python get newest file in directory code sample
