Example analysis of pass statement usage in python

This article is an example of pass statement usage in python. Shared for your reference. Specific analysis is as follows:

1. Empty statements do nothing

2. Ensure that the format is complete

3. Ensuring semantic integrity

4. Take the if statement as an example:

Write in C/C++:

if(true)
; // do nothing
else
{} // do nothing

Write method in python:

if true:
pass # do nothing
else:
print "do something."

Test program: define an empty function

>>> def nullfunc():
...   pass
...
>>> nullfunc()
>>>

I hope that what I have described in this article will help you in your Python programming.
