The traceback says:
Traceback (most recent call last):
File "D:\Documents\PyCharm\Trader\Trader\core\outpost.py", line 18,
in run
with soup.select('div.stat_box
div.value')[0].get_text().replace(',', '') as trades, \
AttributeError: __exit__
As you can see, it does:
soup.select('div.stat_box div.value')[0].get_text()
which, presumably, returns a string, and then it calls the .replace
method on that string, which returns a string.
That string is then bound to 'trades'.
The problem is that this occurs in the expression part of a 'with'
statement.
If you look at this simpler example:
>>> with 'some string' as a_name:
... pass
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: __exit__
An even simpler example:
>>> with 'somestring':
... pass
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: __exit__
