puts and print are pretty much the same thing. puts just creates a new (blank) line after whatever you wanted to display.
The print command just takes whatever you give it and prints it to the screen. puts (for "put string") is slightly different: it adds a new (blank) line after the thing you want it to print. You use them like this:
Either can be used for prompts since it’s just a text phrase. The consideration of which to use is where we wish to position the draw pencil for the next printed character to appear.
print "Enter some text: "
text = "#{gets.chomp} "
print "Enter more text: "
text += gets.chomp
puts "Words to redact (separate by space)"
redact = gets.chomp
redact = redact.split(' ')
which on the console will read, with given inputs, (and as a result of the redaction code, not shown)
Enter some text: Hello
Enter more text: World
Words to redact (separate by space)
Hello
Hello World
REDACTED World
Note the placement of the inputs when print is used, compared to when puts is used.

print "Enter some text: "
text = "#{gets.chomp} "
print "Enter more text: "
text += gets.chomp
puts text
z = text.dup
puts "Words to redact (separate by space)"
gets.chomp.split(' ').each {|x| z.gsub! /\b#{x}\b/i, "REDACTED"}
puts z
Enter some text: foo faz
Enter more text: bar baz
foo faz bar baz
Words to redact (separate by space)
faz baz
foo REDACTED bar REDACTED
I have tried several times but the code will not let me go through to the next section despite even using the prompted solution out of sheer frustration at the endless attempts to pass it. I’m begging here for my sanity, help me.
I got stuck too. The answer is to have a blank line (press enter twice) after you declare the text variable.
Literally adding an extra carriage return will let you proceed. As you rightly point out, it’s crazy because Ruby isn’t supposed to care about whitespace, and the very example on the previous page was laid out without blank lines.
Apparently, others have gotten stuck here on this REDACTED exercise. pasting the “solution” that still doesn’t let you move on… I tried adding the blank line, but that didn’t seem to help… what’s the deal???
puts "Enter some text: "
Can you upload a screenshot (there is an upload button in the post editor) showing a) your code, b) the error message/feedback that pops up at the bottom and c) what you have entered in the terminal ?
I don’t seem to be able to get back to the same place now. the problem I had was that when trying to use the suggested solution which I pasted into the original question, it still didn’t allow me to move on. i skipped to another section. Now, trying to get back to where I got stuck now looks different. Pretty sure I was on 2/6 and now I’m on 3/6 which is similar but is using additional operations. Apologies…
