inDExError

一般外部输入的数据都可能存在问题。所以通常在readlines后要做一次处理 for line in file.readlines(): if not line.strip():continue r = line.split('\t') if len(r)

1.异常种类 python中的异常种类非常多,每个异常专门用于处理某一项异常!!! 下面是一些常用的异常: 2.异常基础 在编程过程中为了增加友好性、容错性和健壮性,在程序出现bug时一般不会将错误信息显示给用户,而是现实一个提示的页面,通俗来...

发代码,用编辑框的代码发,这样子没法看

>>> import random >>> random.randint(1000,9999) 这样不好吗……你这个写的和递归一样,很难理解的。 报的错是说你array3里面没有元素了,都删完了。

执行的哪个命令?

r1 = [] 是空数组,但是你对这个数组 r1[j] = 是怎么个意思?肯定越界嘛,用append吧

代码没什么问题 你看一下文件最后有没有空行导致split函数返回的tmp为空,所以tmp[0]导致了数组越界 分析思路: 1.报错信息里面已经提示了第12有误 2.提示为数组index越界,而12行的代码中tmp[0]涉及数组 3.找到tmp的定义,是split函数分解之后...

You try to index outside the range: for s in range(0, M+1): t[s] = t_min + k*s Change to: for s in range(M): t[s] = t_min + k*s And it works. You create t with length of M: t = np.linspace(t_min, t_max, M) So you can only acces...

winning_numbers[i] The error is that your list indices are out of range--that is, you are trying to refer to some index that doesn't even exist. Without debugging your code fully, I would check the line where you are adding gue...
