print is mandatory for print out in pyspark interpreter ?

[Jeff Zhang]

It is weird to me that I have to use print to get the output. Is it by
design or bug ? The behavior is strange to me as in jupyter user don't need
to use print.

e.g.

%pyspark

# no output
sc.parallelize(range(1, 10)).sum())

# output is printed
print(sc.parallelize(range(1, 10)).sum())

45
