When I am iterating through my variable it gives me an error which I show as below.
Traceback (most recent call last):

TypeError: 'NoneType' object is not iterable
Your function wenjian() does not have any return statements, so it will always return None, by default. That's why Names = wenjian(file) assigns the value None to Names, and so you can't iterate over Names with the for loop.
import os
def wenjian(file):
for root,dirs,files in os.walk(file):
for file in files:
filename = os.path.join(root,file)
print (filename[-28:])
file = ("C:\Users\ZHEN YUAN\Desktop\东航try")
Names = wenjian(file)
for i in Names:
print (i[1])

Above are the uiautomator object viewer screenshots with properties. I am using python package uiautomator installed through pip install uiautomator. I am trying to access the three-dotted settings button through UI automator objects. I have tried using the documentation listed at https://github.com/xiaocong/uiautomator#handler
Here is the code and error:

After all attempts, I am still not able to access the any of the UI objects. Please let me know what am I missing here?
Change:
import uiautomator as uia
d = uia.device()
To:
import uiautomator as uia
d = uia.device
This should solve your problem.
It is happening because you're calling the function device() inside a variable. So "d" is not a function, but use a function to receive a value.
When we call a function using parenthesis Python understands we are calling it and using this result on your variable "d". That's the reason why you're facing "object is not callable", because no object is being passed as parameter to "device()".
When we don't use parenthesis we not call the function, we make a reference to it and the parameters will be passed when we call it.
Hope it helps!
Not a solution to your problem but an alternative: using AndroidViewClient/culebra you can run
culebra -uG -o camera-options.py
once you have the window you can click on the options dots
see the result immediately
and at the same time, the script containing the code to reproduce this action will be generated

I am trying to write to a FieldFile of an instance of a model:
class SourceFile(models.Model):
file_name = models.CharField('File Name', max_length = 100, unique=True)
import_time = models.DateTimeField('Import Time', auto_now_add = True)
local_link = models.FileField(upload_to="ozio/uploaded_files/%Y")
Having no problem when I create the file with:
source_file = SourceFile.objects.create(file_name = source_file_name)
source_file.local_link.save(source_file.file_name, ContentFile('LINE1'))
However when I tried to append new lines:
source_file.local_link.open('a') # Open as append mode
source_file.local_link.write('LINE2')
It complains:
Traceback (most recent call last):
File "<console>", line 1, in <module>
io.UnsupportedOperation: write
When close it and reopen, everything looks ok. Grateful for any suggestion.
>>> source_file, created = SourceFile.objects.get_or_create(file_name = 'Manual.2014.Q2.csv')
>>> source_file.local_link

I have added an assert(0) in a function to understand the sequence of function calls to this function.
Ex:
def my_func():
...lines of code...
assert(0)
...more lines of code...
The logs show only this:
Traceback (most recent call last):
File "/var/www/folder/file.py", line 273, in my_func
assert(0)
AssertionError
I want to see the complete call trace - Example: first_func -> second_func -> my_func
I tried traceback library but it is showing me the same stacktrace.
Please let me know what I am missing here.
Use traceback module for this. I.e.
>>> import traceback
>>> def my_func():
... my_other_func()
...
>>> def my_other_func():
... my_third()
...
>>> def my_third():
... print "Stack"
... traceback.print_stack()
... print "Extracted"
... print repr(traceback.extract_stack())
...
>>>
>>> my_func()
Stack
File "<stdin>", line 1, in <module>
File "<stdin>", line 2, in my_func
File "<stdin>", line 2, in my_other_func
File "<stdin>", line 3, in my_third
Extracted
[('<stdin>', 1, '<module>', None),
('<stdin>', 2, 'my_func', None),
('<stdin>', 2, 'my_other_func', None),
('<stdin>', 5, 'my_third', None)]

Hello I have an Error and I don´t the reason:

I don´t know how to solve this error because I don´t understand it.
Thank you so much.
You have to open your filehandler in binary mode, use wb instead of w:
filehandler = open(b"fruits.obj","wb")
