Golang Read text file and take a slice from one of the read in values
问题
在下面的代码中，我希望读取一个文本文件，每行填写一个1-5的数字。我想要扫描每行并读取其中的一个值，然后判断它是否小于6，并执行相应的操作。不幸的是，我无法获取这些值的切片，它们只会以数组的形式打印出来。请问有什么建议可以修复我的代码吗？
//这部分程序将从名为"file"的文本文件中读取数据
//以了解上次选择的数字，以便第二周的食谱可以是全新的5个数字组合
f, err := os.Open("file")
if err != nil {
fmt.Println(err)
}
for {
var z int
var n int
n, err = fmt.Fscanln(f, &z)
if n == 0 || err != nil {
break
}
fmt.Println("int z:", z)
}

In my code below, I'm hoping to read a text file filled with a number 1-5 per line. I want it to scan the line and read one of values and see if its < 6 and perform an action. Unfortunately I'm unable to take a slice of the values, they only print as an array. Any advice on how i can fix my code please?
//This is the part of the program that will read from a text file named "file"
//To see what numbers were selected last time so the recipe for week two can be
//a completely new recipe group of 5
f, err := os.Open("file")
if err != nil {
fmt.Println(err)
}
for {
var z int
var n int
n, err = fmt.Fscanln(f, &z)
if n == 0 || err != nil {
break
}
fmt.Println("int z :", z)
}

你的代码在我的测试中运行良好。可能文件的格式稍有不同或者位置不同？
for {
var z int
var n int
n, err = fmt.Fscan(f, &z)
if n == 0 || err != nil {
break
}
fmt.Println("int z:", z)
}

Your code worked fine in my test. Likely the file is formatted slightly differently or is in a different location?
for {
var z int
var n int
n, err = fmt.Fscan(f, &z)
if n == 0 || err != nil {
break
}
fmt.Println("int z :", z)
}
