Description

Python interpreter can not handle a syntax where function is called right after function definition is finished. (formatA). However, if a new line is added after function definition, that syntax works fine with python interpreter.

We should not need to add a line after function is defined. In python, we do not require to add a line after function is defined.
Thus, zeppelin interpreter is not handling this situation correctly.
Zeppelin user should be able to run above commandlines without additional space.

formatA

%python
def greet(name):
    print 'Hello', name
greet('Jack')
greet('Jill')
greet('Bob')

output

File "<stdin>", line 3

    greet('Jack')

        ^

SyntaxError: invalid syntax

 Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

NameError: name 'greet' is not defined

 Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

NameError: name 'greet' is not defined

formatB

%python
def greet(name):
    print 'Hello', name

greet('Jack')
greet('Jill')
greet('Bob')
