The pass
statement is used only in the Python programming language. Basically, the pass statement does nothing as it is a null statement. This statement becomes useful in a large number of codes where the programmer just wants to write the function signature and left the function body for future implementation.
while True:
pass
# pass is nothing but a placeholder for any functionality to be added later point of time.
sequence = {'q', 'r', 's', 't'}
for val in sequence:
pass
def function(args):
pass # Remember to implement this later
