以下是从python2.7的 code.py 里复制出来的， 为什么 x=2 没执行到？
filename="<input>"
symbol="single"
from codeop import CommandCompiler, compile_command
compile = CommandCompiler()
x=3
print 'before:',x
code = compile('x=4\nx=2', filename, symbol)
exec code
print 'after:',x
结果是:
before: 3
after: 4
source如果有多行，正确格式应该是什么？
