python code works fine on python shell but not thr

This question already has an answer here:

Why does this work in the Python IDLE shell but not when I run it as a Python script from the command prompt? 4 answers
Python csv import fails 2 answers

as said in the title I'm having problem runnig my code from cmd which is working just fine in python shell.

I have py2neo version 4.

here is my code:

from py2neo import Graph
print ("passed")

here is the output from python shell:

passed
>>>

here is the output from cmd command:

D:\py2neo>python py2neo.py

Traceback (most recent call last):
  File "py2neo.py", line 1, in <module>
    from py2neo import Graph
  File "D:\ALI\Desktop\ayten\mine-py2neo\py2neo.py", line 1, in <module>
    from py2neo import Graph
ImportError: cannot import name 'Graph'

I've been searching, the answer out there were the different versions of python that I have on my system, which has cause this problem. But I checked that out and realized that both of them have the same version.

here is how i figured out the versions:

opening the python shell:

Python 3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:54:40) [MSC v.1900 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.

>>>

in cmd:

D:\py2neo>python --version
Python 3.6.4

D:\py2neo>python
Python 3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:54:40) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

Thank you in advance.

Are you positive that py2neo is installed? What happens if you run pip install py2neo? I've had issues with pip and python versions in the past, so I would make sure that your pip is the same version as your python by running pip --version
