print ('Hello World')
x = 1
wood = 0
coal = 0
    
def found():
    x=0
    x=x+1
    global wood
    wood+=15
    global coal
    coal+=15
    
found()


The variables wood & coal look ambigious to python.

Wood & coal in func "found" are by default treated as local varibles.

use global keyword to fix.
