I'm sure that many people have encountered the following (code for reproduction below) behavior: if during the execution of `@property`, an `AttributeError` is raised and the same class implements `__getattr__` then `__getattr__` is invoked with the name of the property resulting in a confusing message: `AttributeError: 'Foo' object has no attribute 'something'`. If we remove `__getattr__` then we get a more meaningful and correct message: `AttributeError: 'Foo' object has no attribute 'bar'`.

from dataclasses import dataclass

@dataclass
class Foo: val = 'foo_value'

class Test: 
    def __init__(self): 
        self.foo = Foo()

    def __getattr__(self, name):
        return getattr(self.foo, name)
    
    @property
    def something(self):
        return self.foo.bar

t = Test() t.something

The error message is misleading and the behavior catches many people (myself including) in surprise and results in many wasted hours of debugging. I've seen people recommend using a custom decorator (instead of `@property` that catches attribute error) or wrapping your `@property` bodies in `try/except`. But it seems to me that this should be dealt with on language level.

I'm trying to understand a few things:

1. Is this behavior in Python intentional (i.e. is there a good reason) or just stems from the fact that `__getattr__` is invoked when `AttributeError` is raised when an instance attribute is accessed?

2. If not intentional, is there a relatively easy way to detect `AttributeErrors` cause by `@property` execution in CPython? If so, why hasn't this been handled on language level?

3. I've searched CPython issues on Github and I saw someone trying to correct documentation but couldn't find issues asking about this behavior or suggestions to fix - am I missing something?

I've built a webscraper in python (Jupyter) to pull post content from a blog and I would like to use the csv file to create a wordcloud. This is the wordcloud code I am using:

%matplotlib notebook
from os import path
import matplotlib.pyplot as plt
import random

from wordcloud import WordCloud, STOPWORDS

# Open and read blog_stuff csv file
file = open("blog_stuff.csv",'r')
text = file.read()
file.close()

# Generate WordCloud 
# !!!make sure the path for the font is correct!!!
wordcloud = WordCloud(font_path='C:/Windows/Fonts/Calibri.ttf', relative_scaling = 0.25 ).generate(text)

# Save image
plt.savefig('wordcloud.png')

# Display Image
plt.show()

I keep running into an attribute error on all of the tutorials I follow. This is the error:

Would any of you fine folks know how I can remedy this issue?
