In accordance with the following code, the output of the whole is 9,
And want is every cycle to create an object to accommodate different data, ask how can create a new object in each loop?

 

The class Comment () : 
Def __init__ (self) : 
Pass 


Def lop () : 
Comments=[] 
For I in range (10) : 
Comment=the comment 
The comment. Independence idx=I 
Comments. Append (comment) 

The return comments 


If __name__=="__main__ ': 
Comments=lop () 

# print (len (comments)) 

For independence idx in range (len (comments) : 
Print (comments) [r]. Independence idx independence idx)

Why not add parentheses, instantiation of the object can be referenced again? !

The comment. Independence idx=I 
Comments. Append (comment) 

The return comments 


If __name__=="__main__ ': 
Comments=lop () 

# print (len (comments)) 

For independence idx in range (len (comments) :

Line 9:

 
Comment=the comment (#) instantiated need to add brackets

You didn't add parentheses, assignment, the comment is equivalent to the comment, equal to give the comment to add static attribute independence idx

 
The Comment. Independence idx=I

So you append the Comment is a class object, not its instance, independence idx is the Comment of static properties, the final assignment

CodePudding user response:

 
For independence idx in range (len (comments) : 
Print (comments) [r]. Independence idx independence idx)

Look at this writing, is to turn to other language
