用了sys.stdin来处理多组样例

import sys
for line in sys.stdin:
    alist=line.strip().split(';')
    blist=[0,0]
    for each in alist:
        if 2<=len(each)<=3 and (each[0] in "ASWD")and each[1:].isdigit():
            if each[0]=='A':
                blist[0]=blist[0]-int(each[1:])
            if each[0]=='S':
                blist[1]=blist[1]-int(each[1:])
            if each[0]=='W':
                blist[1]=blist[1]+int(each[1:])
            if each[0]=='D':
                blist[0]=blist[0]+int(each[1:])
print(blist[0],end=",")
print(blist[1],end="")
