如何使用python-selenium截取屏幕截图？

Question

here is my simple code of python that I wrote to save the screenshot of a webpage.

from selenium import webdriver
import time
driver=webdriver.Firefox()
driver.get("https://www.google.co.in")
driver.implicitly_wait(2)
driver.save_screenshot("D\amanulla\test.png")
driver.quit()

Though, the program running without any errors, I do not see any screenshots saved on my machine. Can someone help me on this?

Answer 1

You are missing : from "D\\amanulla\\test.png" and you need to escape the \\ as well, so effectively the line will be either:

"D:\\amanulla\\test.png"

or

"D:/amanulla/test.png"

Answer 2

I do not see any screenshots saved on my machine

Look for a file named Dmanulla est.png in the default Downloads location for your browser... because that is what you are instructing WebDriver to do with the line:

driver.save_screenshot("D\\amanulla\\test.png")

Explanation:

The string "D\\amanulla\\test.png" will be interpreted as "Dmanulla est.png" . This is because backslashes are escape sequences within Python strings. Your directory separators will be interpreted as \\a (bell) and \\t (tab).

Also, the : separator is missing between the drive letter and the file path, so it is treating the entire string as a filename. In the absence of a directory name, it should save to browser's default "Downloads" directory.

Solution:

driver.save_screenshot(r"D:\\amanulla\\test.png")

This uses a raw string so the backslashes are not interpreted as escape sequences, and it adds the missing : as the drive letter separator.
