eval with print stmt

[Art]

Hello,

I can't seem to get eval or compile to accept the print stmt, or any
complicated statements.

The documentation I've looked out doesn't explain why this is.

ex:Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "<string>", line 1
print('foo')

but this works:foo

also, I can't get eval to make callable objects. is this possible?Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "<string>", line 1
def foo():
^
SyntaxError: invalid syntax

I'd like to have a command line parameter be turned into a callable
statement with an expected environment (a la awk) but I can't seem to
get this working. (I get the same behavior for compile.

Thanks,
A

eval only works with expressions, and `print ...` is a statement.
So is `def ...` .

exec should do what you want.
