返回： 哈希的字符串表示法。

例子 #1 :

# Ruby code for Hash.inspect() method
 
# declaring Hash value
a = {a:100, b:200}
 
# declaring Hash value
b = {a:100, c:300, b:200}
 
# declaring Hash value
c = {a:100}
 
 
# inspect Value
puts "Hash a inspect form : #{a.inspect()}\n\n"
 
puts "Hash b inspect form : #{b.inspect()}\n\n"
 
puts "Hash c inspect form : #{c.inspect()}\n\n"

输出:

Hash a inspect form : {:a=>100, :b=>200}

Hash b inspect form : {:a=>100, :c=>300, :b=>200}

Hash c inspect form : {:a=>100}

例子 #2 :

# Ruby code for Hash.inspect() method
 
# declaring Hash value
a = { "a" => 100, "b" => 200 }
 
# declaring Hash value
b = {"a" => 100}
 
# declaring Hash value
c = {"a" => 100, "c" => 300, "b" => 200}
 
 
# inspect Value
puts "Hash a inspect form : #{a.inspect()}\n\n"
 
puts "Hash b inspect form : #{b.inspect()}\n\n"
 
puts "Hash c inspect form : #{c.inspect()}\n\n"

输出:

Hash a inspect form : {"a"=>100, "b"=>200}

Hash b inspect form : {"a"=>100}

Hash c inspect form : {"a"=>100, "c"=>300, "b"=>200}
