I have a class MyThread. In that, I have a method sample. I am trying to run it from within the same object context. Please have a look at the code:
class myThread (threading.Thread):
def __init__(self, threadID, name, counter, redisOpsObj):
threading.Thread.__init__(self)
self.threadID = threadID
self.name = name
self.counter = counter
self.redisOpsObj = redisOpsObj
def stop(self):
self.kill_received = True
def sample(self):
print "Hello"
def run(self):
time.sleep(0.1)
print "\n Starting " + self.name
self.sample()
Looks very simple ain't it. But when I run it I get this error
AttributeError: 'myThread' object has no attribute 'sample' Now I have that method, right there. So what's wrong? Please help

Your indentation is goofed, and you've mixed tabs and spaces. Run the script with python -tt to verify.
If you’re using python 3+ this may also occur if you’re using private variables that start with double underscore, e.g., self.__yourvariable. Just something to take note of for some of you who may run into this issue.
These kind of bugs are common when Python multi-threading. What happens is that, on interpreter tear-down, the relevant module (myThread in this case) goes through a sort-of del myThread.
The call self.sample() is roughly equivalent to myThread.__dict__["sample"](self).
But if we're during the interpreter's tear-down sequence, then its own dictionary of known types might've already had myThread deleted, and now it's basically a NoneType - and has no 'sample' attribute.
This may also occur if your using slots in class and have not added this new attribute in slots yet.
class xyz(object):
"""
class description
"""
__slots__ = ['abc', 'ijk']
def __init__(self):
self.abc = 1
self.ijk = 2
self.pqr = 6 # This will throw error 'AttributeError: <name_of_class_object> object has no attribute 'pqr'
I got this error for multi-threading scenario (specifically when dealing with ZMQ). It turned out that socket was still being connected on one thread while another thread already started sending data. The events that occured due to another thread tried to access variables that weren't created yet. If your scenario involves multi-threading and if things work if you add bit of delay then you might have similar issue.
Python protects those members by internally changing the name to include the class name.
You can access such attributes as object._className__attrName.
I have encountered the same error as well. I am sure my indentation did not have any problem. Only restarting the python sell solved the problem.
The same error occurred when I had another variable named mythread. That variable overwrote this and that's why I got error
You can't access outside private fields of a class. private fields are starting with __ .
for example -
class car:
def __init__(self):
self.__updatesoftware()
def drive(self):
print("driving")
def __updatesoftware(self):
print("updating software:")
obj = car()
obj.drive()
obj.__updatesoftware() ## here it will throw an error because
__updatesoftware is an private method.
