However, nothing happens when the pass statement is executed, which is called no operation (NOP).

Let's look at an example:

# pass is just a placeholder for# functionality to be added later.sequence = {'paired,' axed, 'for val in sequence,' s'} for val in sequence: pass

We can also do the same in a function or class:
