Maybe the loop and gsub are causing the confusion. If all you want to do is
replace the value associated with the key, you can simple assign it:

some_hash['Name'] = "New Name"

Is that what you are trying to do?

Jazak Allah Khayr Ammar for your reply.

Maybe your solution is a thing I was thinking of.

But, can you kindly tell me how the gsub! method is working on the
example?

It not a solution really, just the basic syntax.

The gsub! does not replace values in the hash, it is operating on the string
that is returned by gets. Consider the following:

str = "Some short string"
puts str # prints "Some short string"

str.gsub!('short', 'small')
puts str # prints "Some small string"


Adding some print statements can help you see what is going on. Try running
the following:

info = {
'Name' => 'Joe',
'Age' => '20'
}

template = "Name is Age years old"
puts "template = #{template}"

info.each do |key, value|
puts "replacing #{key} with #{value}"
template.gsub!(key, value)
puts "template = #{template}"
end


Hope that helps,
Ammar
