これをハッシュに挿入するにはどうすればよいですか

私のやり方は

%hash = map {chomp ; split /\s+=\s+[0-9]/} (@dblst);

ここで、dblst はデータを含む配列です

私がこれをするとき、私は得ます

いくつかの数値が左側にあることがわかります。すべての数値を右側に配置して、そのハッシュでいくつかの算術演算を実行したいのですが...助けていただければ幸いです

あなたの問題は、使用している正規表現と無制限の分割です。キーと値のみを探しているので、(おそらく) 分割を 2 つのフィールドに制限する必要があります。少数または多数のフィールドに分割されるフィールドが必要な場合は、ハッシュの割り当てが破損します。また、空白で囲まれた等号である区切り記号でのみ分割する必要があります。

あなたの正規表現:

/\s+=\s+[0-9]/

「空白の後に等号が続き、その後に空白が続き、数字が続く」で分割されます。桁が削除されます。のような行を想定するとfoo = 0、結果として のリストが得られます"foo", ""。

必要なものは次のとおりです。

split /\s*=\s*/, $_, 2;

これにより、等号の周りの空白が取り除かれ、最大 2 つのフィールド (おそらくキーと値) のみが返されます。先頭の空白を含むフィールドがまだいくつか見つかりますが、それは許容できると思います。

ステートメントを使用するmapと、リスト全体が返されるという欠点があり、ご覧のとおり、リストが破損する可能性があります。より賢明なアプローチは、for ループを使用することです。

my %hash;
for (@dblst) {
    chomp;
    my ($key, $val) = split /\s*=\s*/, $_, 2;
    $hash{$key} = $val;
}

このコードを使用すると、制御ステートメントを挿入して、空白のキー/値の挿入を防止したり、重複を防止したり、必要な他のあらゆる種類のテストを実行したりすることも簡単になります。
