Dear all,
I want to generate a list composed by rules. That is,
I have two list
First one:
list1={1, 2, 3}
The elements of this list are Integers.
Map[Head, list1] = {Integer, Integer, Integer}
Second one:
list2= {"file1", "file2", "file3"}
The elements of this list are Strings.
Map[Head, list2] = {String, String, String}
What I want is to have a new list like
list3= {1 -> "file1", 2 -> "file2", 3 -> "file3"} Map[Head, list3] = {Rule,
Rule, Rule}
Yes, of cause I can generate a list of rule manually. But what I have are
two big list of many elements and they are the output of other codes. So, in
real life this would be a part of big program. That is why I want to
generate the rule list automatically from list1 and list2. How could I do
this in a simple way? Thank you for your help.
Best regards,
Joug
