Matrix of size 100*100- Meghna

Having trouble with Mock and exception side effects
Hello! I am using Mock to raise an exception in an function as a side effect.
However, Mock is completely redefining the exception itself turning it in to a
MagickMock object, which generates the Python exception
TypeError: catching classes that do not inherit from BaseException is not
allowed
This is my minimal reproducible test case.
# test_case.py
#!/usr/bin/python3
from unittest.mock import patch
import package.module
print('Before patcher start:', package.module.MyException)
patcher = patch('package.module')
mock_hvac = patcher.start()
print('After patcher start:', package.module.MyException)
try:
print('Right before raise:', package.module.MyException)
raise package.module.MyException
except package.module.MyException:
print('Got the exception')
package/__init__.py
# Empty
package/module.py
class MyException(BaseException):
pass
Output:
$ python3.6 --version
Python 3.6.9
$ python3.6 test_case.py
Before patcher start:
After patcher start:
Right before raise:
Traceback (most recent call last):
File "test_case.py", line 21, in
raise package.module.MyException
TypeError: exceptions must derive from BaseException
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "test_case.py", line 23, in
except package.module.MyException:
TypeError: catching classes that do not inherit from BaseException is not
allowed
This is also causing problems for Mock side effects. In this line of code in
mock.py (line 997 for me):
if effect is not None:
if _is_exception(effect):
raise effect
The _is_exception() function checks for an exception via:
return (
isinstance(obj, BaseExceptions) or
isinstance(obj, type) and issubclass(obj, BaseExceptions)
)
Which of course is false, because it's been replaced by a MagicMock object, so
exception side effects aren't properly raised.
According to https://docs.python.org/3.6/library/unittest.mock.html#calling
calling a function after setting the side_effect should raise the Exception,
not a MagicMock object.
https://docs.python.org/3.6/library/unittest.mock.html#unittest.mock.Mock also
says "Alternatively side_effect can be an exception class or instance. In this
case the exception will be raised when the mock is called."
So, this seems to be not behaving as design, or at least not as documented.
This is creating some really serious problems for testing our code, as we want
a function to have a side effect of an Exception, and catch that exception, but
we can do neither when it has been replaced by a MagicMock object.
Thanks for any tips, pointers, or "You're doing it wrong!" education. :)

[RELEASED] Python 3.5.10rc1 is released
On behalf of the Python development community, I'm pleased to finally announce the availability of Python 3.5.10rc1. Python 3.5 is in "security fixes only" mode. This new version only contains security fixes, not conventional bug fixes, and it is a source-only release. Important Notice: The latest releases of Linux (Ubuntu 20.04, Fedora 32) ship with a new version of OpenSSL. New versions of OpenSSL often include upgraded configuration requirements to maintain network security; this new version no longer finds Python 3.5's OpenSSL configuration acceptable. As a result, most or all secure-transport networking libraries are broken in this release on systems where this new version of OpenSSL is deployed. This means, for example, that seven (7) of the regression tests in the test suite now regularly fail. Older versions of Linux, with older versions of OpenSSL installed, are unaffected. We're aware of the problem. Unfortunately, as 3.5 is nearly completely out of support, it has become very low priority, and we've been unable to find the resources to get the problem fixed. It's possible that these problems simply won't be fixed in 3.5 before it reaches its end-of-life. As always we recommend upgrading to the latest Python release wherever possible. You can find Python 3.5.10rc1 here: https://www.python.org/downloads/release/python-3510rc1/ Cheers, //arry/ -- https://mail.python.org/mailman/listinfo/python-list
How do I use the data entered in a form?
I have a simple form that I copied/modified from a python web site. A lot
of it makes sense but I do not see how the form in activated.
Is there some call in there that I am just not seeing?
How do I use the information entered into the form. Everything works here
except for line 30 where I get a "fetch not defined" error. I can send the
entered information to the screen but I do not see how I can use the
information outside the functions defined.
Do I need a "return SR, TSR"?
def Data_Entry(entries):
SR = (entries['Sensor_Reading'].get())
print("SR: ", SR) #This line prints
TSR = (entries['Test_Strip_Reading'].get())
print("TSR: ", TSR) #This line prints
def SubmitForm(entries):
print("Form Submitted")
SR = entries['Sensor_Reading'].get()
print("SR inside = " + SR) #This line prints
def makeform(root, fields):
entries = {}
for field in fields:
row = Frame(root)
lab = Label(row, width=22, text=field+": ", anchor='w')
ent = Entry(row)
ent.insert(0,"0")
row.pack(side = TOP, fill = X, padx = 5 , pady = 5)
lab.pack(side = LEFT)
ent.pack(side = RIGHT, expand = YES, fill = X)
entries[field] = ent
return entries
if __name__ == '__main__':
root = Tk()
ents = makeform(root, fields)
# root.bind('', (lambda event, e = ents: fetch(e)))
#"fetch not defined" reported here
b1 = Button(root, text = 'Submit',
command=(lambda e = ents: SubmitForm(e)))
b1.pack(side = LEFT, padx = 5, pady = 5)
b2 = Button(root, text = 'Quit', command = root.quit)
b2.pack(side = LEFT, padx = 5, pady = 5)
root.mainloop()
SR = (entries['Sensor_Reading'].get())
print ("SR Outside = " + SR)
==
The last two lines were guesses but they still failed.

It will raise what you tell it to raise. You have to maintain a
reference to the original Exception object, so you can continue to use
it after mocking.

Your problem is entirely described by the fact that you point out: the
package.module.MyException name has been pointed to a MagicMock object.
If you don't want that, you have to restore the name to what you want.

[Always tell us how your code fails, please. If there's an exception include
it and the complete traceback in your post.]
In this case you probably get a NameError because 'entries' is a local
variable in makeform(). In the global namespace the person you copied the
code from used 'ents' -- so you have to either use ents, too,

ents = makeform(root, fields)
...
SR = ents['Sensor_Reading'].get()
or rename it

entries = makeform(root, fields)
...
SR = entries['Sensor_Reading'].get()

Again, the author of the original code probably defined a fetch() function;
if you want to use it you have to copy it into your script.
