I know the pass is a reserved keyword which does nothing when interpreted by the python interpreter. I am just curious to know what is the real purpose of it.

Let's say

for i in [1,2,3]:
   pass
   print(i)

When it is interpreted it gives nothing, then what is the purpose of existence of this reserved keyword. I researched a little but not able to find the exact purpose of the pass keyword, Just curious to know.

That for loop isn't valid, so I would expect it to throw an error. – erip Nov 27 '18 at 13:10

To make it possible to use indentation to denote blocks (and not something like { } ) and still make it possible to have empty blocks. There must be some duplicate of this... – RemcoGerlich Nov 27 '18 at 13:13

`pass` is the empty statement, it does *nothing*. You use it when you *must* have a statement syntactically. Like defining an empty function: `def foo(): pass`. You can't leave a function definition empty, you must have at least one statement, so you use `pass`. – Martijn Pieters Nov 27 '18 at 13:13
@RemcoGerlich: already handled. – Martijn Pieters Nov 27 '18 at 13:13
@RanjithUdayakumar Your original code was not valid; it was subsequently fixed. – chepner Nov 27 '18 at 14:42
@chepner, I just missed " : " so that I added it, I was mentioned "it is valid" because erip mentioned "Pass is not valid in Loop". – Ranjith Udayakumar Nov 27 '18 at 14:45
He never mentioned `pass`; he just said the loop wasn't valid, which it wasn't without the `:`. – chepner Nov 27 '18 at 14:50
@chepner oh okay, I misunderstood... – Ranjith Udayakumar Nov 27 '18 at 14:56
