Give it some time to think, before you start code;

-

 Yesterday night, I was solving a problem. I had completed the task in python3. But the clients system runs in python2. So I need to resolve all the dependencies. 

The program runs smoothly, but suddenly I noticed that, the program is generating wrong results. Panic mode was on. I rechecked the code, it was perfect. Back to python3 code again and tested the program. Got the correct answer.  So I started debugging the whole code in python 2 line by line. 


After 5 hours I found the reason for the bug. 

In python2  5/2 will be treated as 2. But in python3  5/2 will be treated as 2.5

 


Yes  the value 0.5 wasted my 5 hours in the life.

Complementary Color

-
    The  wheel is a useful tool to visualize how colors relate to each other - it's a circle where similar hues are neighbors and different hues are farther apart. When two colors are opposite each other on the wheel, they are called complementary colors. They have the characteristic that if they are combined, they "cancel" each other out and create a gray colour. However, when placed side-by-side, these colors appear more vibrant and produce a strong visual contrast. example: red (#FF0000) and cyan (#00FFFF) green (#00FF00) and magenta (#FF00FF) blue (#0000FF) and yellow (#FFFF00)
