为什么我的python代码提交之后全是RE

str=input()
istr=x.split(" ")
for i in range(len(istr)):
    istr[i]=int(istr[i])
N=istr[0]
t = 0
zoo=0;
for i in range(N):
    for j in range(N):
        if(istr[t+1]==0):
            t+=1
            zoo=1 if zoo==0 else 0
            print(t)
        print(zoo,end="")
        istr[t+1]-=1
    print()

可以参考一下下面的代码?

str_ = input().split(' ')[:-1]
long_ = int(str_[0])
before = ''

for i in range(1, len(str_)):
    if int(str_[i])>0:
        if i % 2 == 1:
            before = before + int(str_[i]) * '0'
        else:
            before = before + int(str_[i]) * '1'

for i in range(len(before)):
    if i % long_ == 0 and i>0:
        print()
    print(before[i], end='')

另外，提醒一下，洛谷的输入最后是有一个空格的，split之后还要去掉最后一个空格。

ps.别用关键字作变量！
