Python: “List.append = ‘list’ object attribute ‘append’ is read-only”
Date : March 29 2020, 07:55 AM
seems to work fine I’m trying to write a response from a Solr server to a CSV file. I’m pretty new to python and have been given code to modify. Originally the code looked like this ... >>> list.append
<method 'append' of 'list' objects>
docstats = []
for doc in response.results:
docstats.append(json.loads(doc['status']))
docstats = [json.loads(doc['status']) for doc in response.results]

Prolog How to append new variable to list using predicate like append([Item], List)?
Tag : prolog , By : John Phipps

hop of those help? You need 3 elements: the element to be added, the list without element, the concatenation of these. Then you can't do with 2 elements only. Note that append([Item], List, Result) can be more conveniently written [Item|List] = Result, and Item will be the first element of Result. Then you're not appending. You can do with append(List, [Item], Result)

How to append an element in a list a declared in global , while list.append() statement is inside a function

I hope this helps you . corrected code for query , both var and result are global variables which are required to be accessed inside a function , Remove the word global from your append statement. You have: global result.append(var)
result.append(var)

Python list append to list "AttributeError: 'tuple' object has no attribute 'append'"

With these it helps Tuples are immutable meaning they can't be changed unless reassigned. You can however add tuples to a list because lists are mutable, meaning they can be changed. You need to edit the order of your append. listFollowedBy.append(row)
