Doesn't split string by delimiter in ruby ​​2.7.1p83?

Question

ruby

It is required to split a string in ruby ​​on the separator "\"

Here is an example of a string:
Server username: DESKTOP-AHDESI\Username

Here's how I try:
user_name = "DESKTOP-AHDESI\Username"
print user_name.split("\\")

I get:
Ruby Error: NoMethodError undefined method `gsub!' for ["DESKTOP-AHDESIUsername"]

Slightly late answer:

• In your case, to separate a string with a backslash, you need to put it in single quotes. Double quotes treat the backslash internally as a special character.
  
• I don't know how you got the string, but the method returns it inside an array, which is why we get an error about gsub!. Use user_name.join or username.first to return the value as a normal string.
