现在我如何将其插入哈希
我正在做的方式是
%hash = map {chomp ; split /\s+=\s+[0-9]/} (@dblst);
其中dblst是包含数据的数组

你看到左边有一些数字，我想要所有的数字都在右边，这样我想用那个哈希执行一些算术运算......感谢帮助
答案 0 :(得分：5)
你的问题是你正在使用的正则表达式，以及无限的分裂。由于您只查找键和值，因此您应该（可能）将拆分限制为两个字段。如果您应该有一个分成更少或更多字段的字段，您的哈希分配将被破坏。您还应该只在分隔符上拆分，分隔符是由空格包围的等号。
你的正则表达式：
/\s+=\s+[0-9]/
将拆分为“空格后跟一个等号后跟空格后跟一个数字”。该数字将被删除。假设foo = 0之类的行，您将获得"foo", ""的结果列表。
您需要的是：
split /\s*=\s*/, $_, 2;
这将剥离等号周围的任何空格，并且最多只返回两个字段（键和值，大概是）。你仍然会发现一些包含前导空格的字段，但我认为这是可以接受的。
使用map语句的缺点是它返回一个完整的列表，并且您看到该列表可能已损坏。更明智的方法是使用for循环：
my %hash;
for (@dblst) {
chomp;
my ($key, $val) = split /\s*=\s*/, $_, 2;
$hash{$key} = $val;
}
使用此代码，还可以轻松插入控制语句，以防止插入空白键/值，防止重复，并执行您想要的各种其他测试。
