print function question

[Eric Bishop]

Why does this work:

# start
a = 5

print a, 'is the number'

#end, prints out "5 is the number"

But not this:

# start

a = 5

print a 'is the number'

#end, errors out

The difference here is the comma seperating the variable and the string
literal. Is the comma some sort of concatenation operator or is the comma
necessary in some form of a requirement in the print function, i.e is the
variable a an argument to print as well as 'is th number' another argument
to print?
