求帮我把代码改成可以运行并告诉我错误的点

def encounter(stest,ytest):
red = []
Stests = []
Ytests = []
for line in stest.splitlines():
if not line.isspace() and line != "":
Stests.append(line)

for line in ytest.splitlines():
    if not line.isspace() and line != "":
        Ytests.append(line)

smax = len(Stests)
ymax = len(Ytests)
for step in range(max(smax,ymax)):
    try:
        sworld = Stests[step].split
    except:
        sworld.append("")

    try:
        yworld = Ytests[step].split
    except:
        yworld.append("")
if sworld != yworld:
    red.append((step),sworld[step],yworld[step])
    print(red)

encounter("red demons dragon","star dust dragon")

split() 这个后面的括号没了
还有最后面red.append方法没这样写的吧

先把代码格式贴好吧，这样看都是缩进错误，而且有很多循环条件语句不清楚你的嵌套
