Ruby Study Notes (10)-differences between puts, P, and print

In common: it is used for screen output.

Differences:
After puts outputs the content, it will automatically wrap the text (if the content parameter is blank, only one line feed is output). If the content parameter contains an escape character, the output will first process the escape and then output
P is basically the same as puts, but does not process escape characters in parameters.
Print is basically the same as puts, but the line break is not automatically added to the end after the output content

S = "AAAA \ NBB \ TBB" p sp "*****************" puts SP "******** * ******* "Print s

The output result is (scite Editor Environment ):
"AAAA \ NBB \ TBB"
"****************"
Aaaa
Bb
"****************"
Aaaa
Bb BB> exit code: 0

In addition, when outputting double-byte characters, such as full-width English or Chinese characters, P will output the numbers corresponding to the two bytes instead of the characters.

S = "medium" P sputs sprint s

Running result:
"\ 326 \ 320"
Medium
Medium> exit code: 0
