When using argparse, the error
AttributeError: 'Namespace' object has no attribute 'property'
means that the property is not defined in the args parameter. In this case, you expected to define an argument of the name url, but looking at your code:
parser.add_argument('-u', '--url mongodb://192.168.32.11:27017/test', ...
you created a property called '--url mongodb://192.168.32.11:27017/test'. Your declaration should be:
parser.add_argument('-u', '--url', ...
You can't put a value in with the declaration; maybe you meant to define a default instead?
parser.add_argument('-u', '--url',
type=str,
required=False,
default='mongodb://192.168.32.11:27017/test',
help='Mongo DB URL for Backups')
The same applies for the other argument defined.

Python list with Vcenter vm

import python with __main__ method

I have a python script that have __main__ statement and took all values parametric.
I want to import and use it in my own script.
Actually I can import but don't know how to use it.
As you see below, __main__ is a bit complicated and rewriting it will take time because I even don't know what does most of code mean.
Want to know is there any way to import and use the code as a function?

No, there is no clean way to do so. When the module is being imported, it's code is executed and all global variables are set as attributes to the module object. So if part of the code is not executed at all (is guarded by __main__ condition) there is no clean way to get access to that code. You can however run code of this module with substituted __name__ but that's very hackish.
You should refactor this module and move whole __main__ part into a method and call it like this:
def main():
do_everything()
if __name__ == '__main__':
main()
This way consumer apps will be able to run code without having to run it in a separate process.
Use the runpy module in the Python 3 Standard Library
See that data can be passed to and from the called script
# top.py
import runpy
import sys
sys.argv += ["another parameter"]
module_globals_dict = runpy.run_path("other_script.py",
init_globals = globals(), run_name="__main__")
print(module_globals_dict["return_value"])
# other_script.py
# Note we did not load sys module, it gets passed to this script
script_name = sys.argv[0]
print(f"Script {script_name} loaded")
if __name__ == "__main__":
params = sys.argv[1:]
print(f"Script {script_name} run with params: {params}")
return_value = f"{script_name} Done"
by what your saying you want to call a function in the script that is importing the module so try:
import __main__
__main__.myfunc()

Python: launch default mail client on the system

I'm fairly new to Python and I'm trying to write a plugin for a text editor.
I want to know if there is a way to launch default system E-Mail client from python code.
With pywin32:
import win32api
win32api.ShellExecute(0,'open','mailto:',None,None ,0)
Update
Ah, I misread your question and presumed you're on Win platform.
A platform independent solution would be open mailto link in a browser, like
import webbrowser
webbrowser.open('mailto:', new=1)
Update 2

Enjoy.
The above-mentioned code only works in Python 2.
I've modified it to work for Python 3. The "attach" parameter is no longer supported for security reasons.
