If you want to handle multiple tabs using an automation test in Python-selenium on LambdaTest, you can use the follwing steps. You can refer to sample test repo here.

To open a new tab, you can use the following line of code:

driver.execute_script("window.open('about:blank','secondtab');")

To switch to the new tab, you can use the following line of code:

#by using tab name
driver.switch_to.window("secondtab")

or

#by using tab id
driver.switch_to.window("2")

python lambdatest.py
