Given a square, each point in the grid is composed of an open space, lawn, and a wall. A robot can be placed in each blank space, and each robot can scan the laser in four directions, therefore, a solution should be given to place enough robots on the board. The laser can pass through the lawn but cannot pass through the wall.

An existing string, you need to remove the first paragraph separated by a space, as follows
>>> Product_model = ' ws-c2960g-24tc-l–fixed Module 0′>>> product_model.split (") [0]' Ws-c2960g-24tc-l '
Split () with no parameters takes all spaces (spaces, tabs, newline characters) as delimiters, and if these are "spaces," you can write
>>> Product_model = ' ws-c2960g-24tc-l–fixed Module 0′>>> product_model.split () [0]
The use of filter is more filter
