The simplest statement is the empty statement i.e., a statement which does nothing. In python an empty statement is pass statement.

Whenever the python encounters a pass statement, python does nothing and move to next statement in the flow of control.

A pass statement is useful in those instances where the syntax of the language requires the presence of a statement but where the logic of the program does not.

syntax:-

for variable in sequence:
     pass

e.g.,

l =['A', 'B', 'C', 'D', 'E'] 
for i in l: 
	if(i =='A'): 
		pass
	else: 
		print(i)

output-
B
C
D
E

This is all about pass statement in python.
