import cv2 doesn't give error on command-Prompt but error on IDLE on Windows 10, Python 3.6.4

Question

I have Installed Python 3 (32bit) on Windows.

I have read this answer, but I can't install cv2 using pip install opencv_python-3.4.1-cp37-cp37m-win32.whl and it gives error as

opencv_python-3.4.1-cp37-cp37m-win32.whl is not a supported wheel on this platform.

when I tried Python shell, and run the command import cv2 it doesn't give error, but when I try it as import cv2 in IDLE terminal, then It gives error as

>>> import cv2
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    import cv2
ModuleNotFoundError: No module named 'cv2'

You could also install opencv in these three easy steps

Type py -m pip install opencv-python
In the same window type python or open IDLE python.
Now type import cv2. there you go... simple and easy i hope it helps.

1)Download OpenCV from here

2)Extract the zip file to Root drive(mostly 'C'Drive)

3)Goto folder opencv\build\python\2.7\x86 and copy cv2 file to your main Python directory,

in my case Python directory is

C:\Users\Deshmukh Brothers\AppData\Local\Programs\Python\Python36-32\Lib\site-packages

and paste cv2 file there.

4)Run command as python -m idlelib and now it will prompt idle-shell.

5)now it will work as import cv2, it nothing occurred and cursor went to next line then it is successfully installed.
