It does the same than puts
but calls inspect
instead of to_s
on the object.

I am currently trying to parse a file in ruby and I ran into this example in the open uri module documentation (http://ruby-doc.org/stdlib-1.9.3/libdoc/open-uri/rdoc/OpenURI.html):
open("http://www.ruby-lang.org/") {|f|
f.each_line {|line| p line}
}
Do you guys know what the variable p in "|line| p line" is?
Thanks.

其他提示
p() → nil
For each object, directly writes obj.inspect followed by a newline to the program’s standard output.
That's method
