py"print 'hello world'" fails in Julia 0.6

[rahulkp220]

I am trying to run this code, but it fails throwing these errors.

julia> py"print 'hello world'"
ERROR: PyError (ccall(@pysym(:Py_CompileString), PyPtr, (Cstring, Cstring, Cint), sb, fname, input_type)) <type 'exceptions.SyntaxError'>
SyntaxError('invalid syntax', ('/Users/rlakhanpal/.julia/v0.6/PyCall/src/pyeval.jl', 1, 5, "print 'hello world'"))

If you give py"..." a single-line input, then it is equivalent to the eval function in Python, and eval doesn't support the print statement even in Python:

>>> eval("print 'hello world'")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    print 'hello world'

To evaluate print in Python, you have to do exec, and this is done by py"""...""" when you give it a multiline string:

julia> py"""
       print 'hello world'
       """
hello world

I've updated the README to clarify this.

Thank you! This works.

julia> py"""
       print 'hello world'
       """
hello world
