Issues with Python

[Ode Idoko]

Hi, I am new to Python and though I have been able to download the 3.6 version on my laptop , I still have issues with the syntax. While writing a program to execute, it will display syntax error with different shades of color usually green or yellow. 
What can I do about this? How do I know the error and effect it? Can't it be programmed like we have in excel that will tell you error and prompt you if you wish to accept the right formula format? 
Please I need more information on this. 
Thanks.
