I really don't understand what causes the problem, could someone point it out for me please?
with shelve.open(obj_path) as obj:
for as_num in obj['as_number_list']: # ignore warning, obj['as_number_list'] is a list
temp = charge_as(obj['as_' + str(as_num)]) # temp is an object
as_test = temp # doing like this is ok
print(type(as_test))
exec("as_{}_obj = {}".format(as_num, temp)) # **error here**
And it gives syntax error like this:
<class 'instruments.AS'>
Traceback (most recent call last):
File "...", line 45, in <module>
exec("as_{}_obj = {}".format(as_num, temp))
File "<string>", line 1
as_1_obj = <instruments.AS object at 0x000002A86732E290>
^
SyntaxError: invalid syntax
I tried
exec("as_{}_obj = {}".format(as_num, temp.__dict__))
no error is shown but now as_{}_obj is of class 'dict' instead of class 'instruments.AS'
line 45:
exec("as_{}_obj = temp".format(as_num))

class Student:
def __init__(self,first,last,id):
self._first_name = first
self._last_name = last
self._id_number = id
self._enrolled_in = []

In the code above, i am getting the error as:

return self._enrolled_in()
TypeError: 'list' object is not callable
I am trying to solve the error, but unable to do so. Can anybody help me here.
You have defined self._enrolled_in but you're adding it to self.enrolled_in
Missed the underscore (self._enrolled_in.append)
You have called the attribute _enrolled_in in your __init__() method. In the enroll_in_course() method you're trying to append to enrolled_in which does not exist. So try by adding the underscore in front.
You are missing an _ in the appended statement. You should write self._enrolled_in.append(course) on your enroll_in_course method.
I don't success to fix this error on my code. Python wrote me this error message:

I have pmatches as a separate dictionary, and I don't have the coding skills to fix this issue. (Line 145 is printPredictions(pmatches)
If you're getting 'str' object is not callable when you try to call printPredictions, that means that by the time your program reaches line 645, the name printPredictions was reassigned to a string. Somewhere in your code you have something like
printPredictions = someStringValueGoesHere
You should choose a different name for that variable, or delete the line entirely.
foobar = someStringValueGoesHere
I've tried two different versions of the same function:
def position_of(self, table_name, column_name):
positions = self.heading_positions()
position = positions['{t}.{c}'.format(t=table_name, c=column_name)]
return position
-
def position_of(self, table_name, column_name):
positions = self.heading_positions()
try:
position = positions['{t}.{c}'.format(t=table_name, c=column_name)]
except KeyError:
raise RuntimeError('No heading found for {t}.{c} in import profile "{ip}"'.format(t=table_name, c=column_name, ip=self))
return position
With the first version, I get the following error, which is fine:
Traceback (most recent call last):
File "./import.py", line 15, in <module>
g.process()
File "/home/jason/projects/mcifdjango/mcif/models/generic_import.py", line 39, in process
row.process()
File "/home/jason/projects/mcifdjango/mcif/models/csv_row.py", line 18, in process
self.save()
File "/home/jason/projects/mcifdjango/mcif/models/csv_row.py", line 26, in save
self.output("Phone: " + self.value('customer', 'phone'));
File "/home/jason/projects/mcifdjango/mcif/models/csv_row.py", line 60, in value
print self.generic_import.import_profile.position_of(table_name, column_name)
File "/home/jason/projects/mcifdjango/mcif/models/import_profile.py", line 22, in position_of
position = positions['{t}.{c}'.format(t=table_name, c=column_name)]
KeyError: 'customer.phone'
But the second version - the one that has the more informative error description - fails silently. Why is this?
The second version of position_of works fine for me. I have turned it into a minimal complete program as follows:
class Test(object):
def heading_positions(self):
return {}
def position_of(self, table_name, column_name):
positions = self.heading_positions()
try:
position = positions['{t}.{c}'.format(t=table_name, c=column_name)]
except KeyError:
raise RuntimeError('No heading found for {t}.{c} in import profile "{ip}"'.format(t=table_name, c=column_name, ip=self))
return position
a = Test()
a.position_of('customer', 'phone')
When I run this (using Python 2.6.6 on MacOS X) I get the following error message as expected:
Traceback (most recent call last):
File "./a.py", line 17, in <module>
a.position_of('customer', 'phone')
File "./a.py", line 13, in position_of
raise RuntimeError('No heading found for {t}.{c} in import profile "{ip}"'.format(t=table_name, c=column_name, ip=self))
RuntimeError: No heading found for customer.phone in import profile "<__main__.Test object at 0x100426ad0>"
This shows that catching the KeyError and turning it into a RuntimeError works fine. Does this example work for you? As Sven already writes, a possible explanation would be if you catch RuntimeError but not KeyError somewhere in the call chain.
