问题描述

我试图从文件中读取每行包含一些整数



但是,当我给这样的

  

错误来自 code>是一个函数,你试图用

您的代码中的另一个问题是 int(a) - 因为您有一个 Int64 ,你也应该在解析时指定相同的类型,例如, push!(arr,parseint(Int64,a)) p>

I am trying to read from a file where each line contains some integer

But when I gave like this

f=open("data.txt")
a=readline(f)
arr=int64[]
push!(arr,int(a))

I am getting

ERROR: no method getindex(Function)
 in include_from_node1 at loading.jl:120
解决方案

The error comes from int64[], since int64 is a function and you are trying to index it with []. To create an array of Int64 (note the case), you should use, e.g., arr = Int64[].

Another problem in your code is the int(a) - since you have an array of Int64, you should also specify the same type when parsing, e.g., push!(arr,parseint(Int64,a))
