About how ICODE of 50 close solution, turn to for help-CodePudding

Small robots==Dev craft Spaceship flying plate=Flyer,1,2,3,4 [0]
Rule: before and after the Dev can turn right or left, forward and backward step (a) or step (a)
The ship can carry Dev, fly plate can only be the direction of arrow,
Using a for loop makes Dev to collect all chips,

Question: 1. The cycle of flying plate 4321 how to simplify?
2. Finally a=a - 1 why not execute cycle?

For I in range (4) : 
Flyer [I]. Step (4 - I) 
Spaceship. Step (1 + I) 
Dev. Step (- 2 - I) 
Dev. Step (2 + I)
