Anchor based activity is used in RPA to locate elements on a screen based on a fixed reference point.

• Anchor based activity uses a fixed reference point called an anchor to locate other elements on a screen.

• The anchor can be a nearby label, image, or any other element that remains constant.

• By using the anchor, the RPA bot can accurately identify and interact with other elements relative to the anchor.

• This technique is useful when the position of elements on a screen may vary b...read more

The '#' symbol is used to comment code in Python.

• Use the '#' symbol to comment a single line of code.

• Use triple quotes (''' or ") to comment multiple lines of code.

• Comments are ignored by the Python interpreter and are used to explain the code.

• Python 3.9.0 also included performance optimizations and security updates.

The output of Len("Yash") is 4.

• Len() is a function in many programming languages that returns the length of a string.

• In this case, the string is "Yash" which has 4 characters.

• Therefore, the output of Len("Yash") is 4.

Python scripting is a way to automate tasks using Python programming language.
