Using Commas

[Back] <- - + - -> [Next]
A comma is used to separate consecutive values to be printed.
A comma at the end of a line allows printing to continue on that line.
The comma is not printed but appears as a single space.
A space after a comma can improve readability but is not printed.

print 'Hello', 'World'
print
print 'Hello',
print 'World'

Running the code produces this output:

Hello World Hello World
