Example analysis of assert usage in Python

The example in this article describes the assert usage in Python. Share to everyone for your reference. The specific analysis is as follows:

1. The Assert statement is used to declare that a condition is true.

2. If you are very confident that there is at least one element in the list you are using, and you want to test this and throw an error when it is not true, then the Assert statement is the ideal statement to apply in this case.

3. When the Assert statement fails, a assertionerror is raised.

Test procedure:

>>> mylist = [' Item ']>>> assert Len (mylist) >= 1>>> mylist.pop () ' Item ' >>> assert Len (mylist) >= 1Traceback (most recent call last): File "
 
 
  
  ", line 1, in 
  
  
   
   ASSERTIONERROR>&G t;>
  
  
 
 

Hopefully this article will help you with Python programming.
