I've created a pandas DataFrame with data from loops (data saved here). Now, I want to iterate over this DataFrame. However, when I try to access the items() function like this:
frame = pandas.read_csv(data_path + '/file1.csv')
frame.items()
I get this error:
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "C:\Python27\ArcGIS10.7\lib\site-packages\pandas\core\generic.py", line 2668, in __getattr__
return object.__getattribute__(self, name)
AttributeError: 'DataFrame' object has no attribute 'items'
This is especially weird since PyCharm offers me the option to fill in items if I just type frame.it
What does this mean?
Check your pycharm interpreter. Normally the attribute 'items' works well in Python 3.x but gives the error "AttributeError: 'DataFrame' object has no attribute 'items'" in Python 2.7.
I also faced the same error until I realized that I was using Python 2.7 instead of Python 3.9 that I intended to use.

I am trying to execute the following code and it keeps giving me the error 'DataFrame' object has no attribute 'DATE'. So I can investigate and prevent a future error message, can someone define what is happening in the line of code I am executing?
Here is the code I am running:
final = summary[(summary.DISPATCH_DATE >=dt.date(2022,1,1)) & (summary.DISPATCH_DATE <=dt.date.today())]
I want to do correspondence analysis for the categorical features in my dataset but get this error.
import mca
mca_counts = mca.MCA(test.drop('ID', axis=1))
Traceback (most recent call last):
File "<pyshell#22>", line 1, in <module>
mca_counts = mca.MCA(test.drop('ID', axis=1))
AttributeError: 'module' object has no attribute 'MCA'
Apparently, the latest version of the library in PyPI is 1.0, where the class is called mca.mca. It was renamed to mca.MCA only in 1.0.1, but that version for some reason has never made it to PyPI. Consider either using mca.mca, or reinstalling it from git, or finding something less abandoned.
I get the following error when trying to execute the following in Python with the PuLP library
for i in range(0, items):
print('x{0} = {1}'.format(i+1, value('x{0}'.format(i+1))))
That is my code which throws the following error
Traceback (most recent call last):
File "C:/Python34/knapsack.py", line 81, in <module>
print('x{0} = {1}'.format(i+1, value('x{0}'.format(i+1))))
File "C:\Python34\lib\site-packages\pulp-1.6.1-py3.4.egg\pulp\pulp.py", line 1990, in value
else: return x.value()
AttributeError: 'str' object has no attribute 'value'
My question is why does this not work. Splitting the print statement tends to work correctly.
The value method expects a PuLP variable object, not a string with the same name as one.
In order to evaluate your string back to a python variable, you need to eval it, so that would look like.
value(eval('x{0}'.format(i+1)))
I'm writing a program that solves a tetravex and I encountered this error:
AttributeError: 'list' object has no attribute 'PlacementList'.
I tried everything I know but don't know why I'm getting that error. Could you please tell me what I did wrong?
This is a pastebin link to my code: http://pastebin.com/d1WdbCUu
It happens when you are trying to get PlacementList attribute of a list, obviously.
Here is the example:
>>> a = []
>>> a.PlacementList
Traceback (most recent call last):
File "<pyshell#49>", line 1, in <module>
a.PlacementList
AttributeError: 'list' object has no attribute 'PlacementList'
Just find the code where something similar happens - you are trying to get PlacementList attribute of the object that can be of type list.
I wrote this tiny Python snippet that scrapes a feed and prints it out. When I run the code, something in the feed triggers the error message you see here as my question. Here's the complete console output on error:
> Traceback (most recent call last):
> File "/home/vijay/ffour/ffour5.py",
> line 20, in <module>
> myfeed() File "/home/vijay/ffour/ffour5.py", line
> 15, in myfeed
> sys.stdout.write(entry["title"]).encode('utf-8')
> AttributeError: 'NoneType' object has
> no attribute 'encode'
> sys.stdout.write(entry["title"]).encode('utf-8')
This is the culprit. You probably mean:
sys.stdout.write(entry["title"].encode('utf-8'))
(Notice the position of the last closing bracket.)
Lets try to clear up some of the confusion in the exception message.
The function call
sys.stdout.write(entry["title"])
Returns None. The ".encode('utf-8')" is a call to the encode function on what is returned by the above function.
The problem is that None doesn't have an encode function (or an encode attribute) and so you get an attribute error that names the type you were trying to get an attribute of and the attribute you were trying to get.
