Analysis of the function of comma after the Python assignment statement

This example describes the role of a comma after a python assignment statement. Share to everyone for your reference. The specific analysis is as follows:

IDLE 2.6.2

>>> a = 1>>> b = 2,>>> print type (a)
 
 
  
  >>> print type (b)
  
  
   
   >>> c = []>>> d = [],>>> print type (c)
   
   
    
    >>> print type (d)
    
     
    
   
   
  
  
 
 

After a comma is added to the assignment expression, a tuple object is automatically obtained, and the desired result is not obtained when some type-related work or serialization is required. When you encounter a similar phenomenon in your work, you can put this into your own checklist.

>>> Print c[]>>> print D ([],) >>> print a1>>> print B (2,)
