Python has the syntactical requirement that code blocks (i.e. after if, except, def, class etc.) cannot be empty. Empty code blocks are however useful in a variety of different contexts, such as when you are designing a new class with some methods that you don't want to implement yet.

class MyClass():

def meth_a(self):
pass
def meth_b(self):
print("I'm meth_b")

If you had left out the pass keyword, the code wouldn't run. You would get the below error:

IndentationError: expected an indented block

To summarize, the pass statement does nothing particular but can act as a placeholder to prevent IndentationError.
