Pixel Grid (Problem 42) - InfyTQ Solution in Python

Pixel Grid (Problem 42)

InfyTQ Solution in Python

PROBLEM STATEMENT

CSE160-Midterm-2015 Spring

Write a function maxvalue_in_column(pixel_grid)
that, given a list of lists of integers, creates a list of integers that includes the maximum value found in each column of pixel_grid.

You can assume that pixel_grid will always contain at least one row and one column and that the values in pixel_grid will be between 0 and 255 and that each row will contain the same number of columns.

Here are a few examples. After the following code is executed:

If pixel_grid contains	Col_list will be
[ [ 4, 2, 3], [16, 5, 0], [ 3, 200, 6], [ 0, 10, 12] ]	[ 16, 200, 12 ]
[ [ 4 ], [ 16 ], [ 3 ], [ 0 ] ]	[ 16 ]
[ [ 4, 2, 3] ]	[ 4, 2, 3 ]
[ [6] ]	[ 6 ]

SOLUTION

#PF-Prac-42 def maxvalue_in_column(pixel_grid): #start writing your code here result_list = [] # For each column, find its max, append to result for col in range(len(pixel_grid[0])): max_val = 0 # Find max value over all rows, in this column for row in range(len(pixel_grid)): if pixel_grid[row][col] > max_val: max_val = pixel_grid[row][col] result_list.append(max_val) return result_list pixel_grid=[[ 4, 2, 3], [16, 5, 0], [ 3, 200, 6], [ 0, 10, 12]] pixel_grid1=[[ 4 ], [ 16 ], [ 3 ], [ 0 ]] pixel_grid2=[[ 4, 2, 3]] pixel_grid3= [[6]] print("Pixel grid is:") for i in pixel_grid: print(i) output=maxvalue_in_column(pixel_grid) print("The maximum values of each column are:",output)
