ExplicitWait.py

# Sometimes selenium needs to wait few seconds for the elements to appear or to finish loading etc
# it is a bad practice to use time.sleep() aka Thread.sleep in java because it is a static wait
# that is why its always a good practice to use dynamic waits like implicit wait or explicit waits
# Implicit Wait -> global wait for the whole driver object applicable to each step the driver do
# Explicit wait -> target only specific element for a condition to be happened
# pause the test for few seconds -> time.sleep # BAD PRACTICE and its python not a selenium
