How to Automate File Uploads in Python with Selenium and PyAutoGUI

Introduction

In a recent Python community discussion, a member asked how to automate the file‑upload dialog that appears when using Selenium.

Implementation

One suggestion was to use Selenium to move the mouse to the screen coordinates of the file‑selection window and click, which works but is brittle.

Another, more reliable approach uses the pyautogui library to control the OS dialog. The following code demonstrates how to locate the “File Upload” window, type a file path, and click the “Open” button.

# -*- coding: utf-8 -*-
import pyautogui
import pywinauto

app = pywinauto.Desktop()
dlg = app['文件上传']
dlg['Edit'].type_keys("Hello, World!", with_spaces=True)
dlg['打开(&O)'].click()

Conclusion

The article presents a concrete solution for automating file uploads in Selenium using pyautogui, helping Python developers overcome this common obstacle.

When posting questions, it is recommended to provide a small, anonymized data sample, the relevant code, and any error screenshots; for longer scripts, attach a .py file.
