Conversion of string to dictionary - python

I have captured a string from a REST get request and have placed it in a variable. The string is:
{"name":"na1mailboxarchive","objectCount":49564710,"dataBytes":36253526882451},{"name":"na1mailboxarchive2","objectCount":17616567,"dataBytes":13409204616615}
I am trying to convert it to a dictionary so I can increment through it and capture the bucket name, size and object count. I have tried eval()
bucket_dict = eval(bucket_info)
but the program errors out with a:
Traceback (most recent call last):
File "./test.py", line 83, in <module>
for k,b in bucket_dict.items():
AttributeError: 'tuple' object has no attribute 'items'
When I print the value of bucket_dict I get:
({'name': 'na1mailboxarchive', 'objectCount': 49564710, 'dataBytes': 36253526882451}, {'name': 'na1mailboxarchive2', 'objectCount': 17616567, 'dataBytes': 13409204616615})
I think the foul up is the () at the beginning and the end of the dictionary. Nothing else I have tried works either.

Try this instead
import ast
string = '{"name":"na1mailboxarchive","objectCount":49564710,"dataBytes":36253526882451},{"name":"na1mailboxarchive2","objectCount":17616567,"dataBytes":13409204616615}'
result = ast.literal_eval(string)
print(result)
result is returned as a dictionary

I got it figured out.
Firstly the json return from the REST API get is badly formatted. I will take that up with the vendor. Secondly I used some iof the infrmation form #PrashantKumar and #MisterMiyagi to sus out the issue I was having. In my original code I had loaded the list with:
bucket_info = [acct_string[acct_string_start+11:acct_len-4]]
The variable was capturing the leading "[" and trailing "]" as a part of the string. Once I removed them then the list behaved correctly and I now can work with it. Thank you for the information and the trail markers.

Python - parking JSON file and stucked at empty .items()

So I am parsing some JSON file and it always breaks when code gets to one that has empty '' value for .items():
for i,n in v['objects'].items():
I get:
AttributeError
'str' object has no attribute 'items'
Whenever code gets to some item that has field:
"objects": ""
Does anyone know how to handle this? I tried with checking first if it is empty, but no success.
I tried with this before my FOR:
objects_empty = ""
if not v['objects'].items() == objects_empty:
Thanks!
[From the earlier comment]
v['objects'] is the value that can be an empty string instead of a dictionary. Hence, you want to check whether this value equals the empty string and not its .items(). A string doesn't have items, that's what the error message complains about.
You can change it to this:
if v["objects"] != "":

Problem with making a Reddit bot in python

I'm trying to program a reddit bot, but get this error message:
Traceback (most recent call last):
File "main.py", line 64, in <module>
run_bot(r, comments_replied_to)
File "main.py", line 34, in run_bot
comments_replied_to.append(comment.id)
AttributeError: 'filter' object has no attribute 'append'
Here is my code: https://pastebin.com/caz14jm7
I think I have to change append into a list, but I don't know how to do that
Part of this is a version difference. In Python 2, filter returned a list. In Python 3, filter returns a generator, which you are treating like a list. The filter generator does not have an append method.
So, you just need to turn it into a list:
comments_replied_to = list(filter(None, comments_replied_to))
Or, even better (in the opinion of many):
comments_replied_to = [k for k in comments_replied_to if k]
I have 2 potential solutions for you,
solution 1:
Line 55 You can change like this
comments_replied_to = List(filter(None, comments_replied_to))
so that, your get_saved_comments() will return a list.
This will help you use the append method and comments_replied_to.append(comment.id) should work without any error
Solution 2:
Line 60: You can change like this
comments_replied_to = list(get_saved_comments())
As long as comments_replied_to is a list type, it will allow you to append method without any issues.

Object has no attribute 'split()' Python

Having an error where i'm trying to get the first work from a string that is passed in to a method within a class. But i am getting AttributeError: 'Deck' object has no attribute 'split' when I run. The 'new_card' that is passed in will be for example 'Two of Hearts'. and new_Card is a string and self.values is a dictionary
# returns integer value of a card
def get_card_value(self, new_card):
return self.values[new_card.split()[0]]
and the error:
Traceback (most recent call last):
File "/home/andypaling/Documents/Programming/python/random/card_game/game.py", line 146, in
if not Game.check_same_cards(player1_deck, player2_card):
File "/home/andypaling/Documents/Programming/python/random/card_game/game.py", line 87, in check_same_cards
if card1.get_card_value(card1) == card2.get_card_value(card2):
File "/home/andypaling/Documents/Programming/python/random/card_game/game.py", line 40, in get_card_value
split_string = new_card.split(' ')
thanks for any help
Hey it seems like you are using a diffrent data type and not a string in your case judging that your making a card game i am guessing you are using a tuple. Try converting the data to a string then split it using the .split() function.
I hope this can help.

Edit embedded document in mongodb using python(pymongo)

I am getting following error while updating a document inside a collection in mongodb using python using pymongo. Any help is greatly appreciated.
x = 4
str = "ratings.${x}.rating"
db.amitava1.update({"_id":1},{"$inc":{[str]:1 } } )
Traceback (most recent call last):
File "", line 1, in TypeError: unhashable type:
'list'***
Youre getting that error because you're doing {"$inc":{[str]:1 }}. Namely, trying to assing [str] as the key in the in the dictionary {[str]:1 }.
It says that because you cannot use a list as a key for a dictionary, because a list is unhashable. You can only use hashable types (types that have a __hash__ function defined) key values.
It looks like you have some other issues with your code though. I think you need to use
str = "ratings.${x}.rating".format(x=x)
or something in order to replace the x in your string.

Find Hyperlinks in Text using Python (Follow-up to another post)

In regards to (Extracting a URL in Python) I have a follow-up question. Note: I'm new to SO and Python, so feel free to correct me on etiquette.
I pulled the regex from the above post and this works fine for me:
myString = """ <iframe width="640" height="390" src="http://www.youtube.com/embed/24WIANESD7k?rel=0" frameborder="0" allowfullscreen></iframe> """
print re.search("(?P<url>https?://[^\s]+)", myString).group("url")
However what I really need to do is loop through a data set that I have previously retrieved from a database. So I did the below, which gives me a strange error, also below.
# Note: "data" here is actually a list of strings, not a data set
for pseudo_url in data:
print re.search("(?P<url>https?://[^\s]+)", str(pseudo_url)).group("url")
Error:
Traceback (most recent call last):
File "find_and_email_bad_press_urls.py", line 136, in <module>
main()
File "find_and_email_bad_press_urls.py", line 14, in main
scrubbed_urls = extract_urls_from_raw_data(raw_url_data)
File "find_and_email_bad_press_urls.py", line 47, in extract_urls_from_raw_data
print re.search("(?P<url>https?://[^\s]+)", str(pseudo_url)).group("url")
AttributeError: 'NoneType' object has no attribute 'group'
When I Google this I find tons of irrelevant posts, so I was hoping SO could shed some light. My hunch is that the regex is blowing up on some null data, special character, etc., but I don't know enough about Python to figure it out. Casting to a string didn't help either.
Any ideas or workarounds to power through this would be much appreciated!
Your regex is not finding a url in every string in data. You should check to make sure you have a match before making the call to group:
for pseudo_url in data:
m = re.search("(?P<url>https?://[^\s]+)", pseudo_url)
if m:
print m.group("url")
You don't need the call to str() either if pseudo_url is already a string.
And as #Blender suggested in his comment, if data is really lines read from an HTML file, you may want to consider using Beautiful Soup instead of regex for this.
