Question

How to write this code in python？

Linear Interpolation Write a program that will create a linear interpolation between two pixels. You are to read in two pixel values and generate a number of pixels specified between them. Input for the program 1 Enter the first pixel value: 0x002222 2 Enter the second pixel values: OxFFDD3:3 3 Enter the number of pixels to generate inbetween: 3 Using the 2 pixels specified it will generate 3 new pixels between the first and second pixel. You will need to round the difference of each channel between the larger and smaller pixel. You will find the channel (Red, Green, Blue) difference between the two pixels and divide by the number of total pixels create the new pixels 1 Colours: 2 0x002222 3 0x405126 4 0x80802a 5 0xc0af2e 6 Oxffdd33 Your program will use the smallest pixel (integer representation of the pixel) as the starting point Example 1 $ python3 ріх.ру 2 Enter the first pixel: 0x002222 3 Enter the second pixel: 0xFFDD33 4 Enter the number of colours to generate in between: 3 5 Colours: 6 0x002222 7 0x40S126 8 0x80802a 9 0xc0af2e 10 0xffdd33

#some values generated are slightly different by 1
#for example for the 5 the value i have got bf but in the question it is c0
#that's it all the values got the right answers
#for some values it is differed by 1
#pix.py
#function that returns the r,g,b values or else returns -1
