funcname = "func"
func = "def %s():\n" % funcname
funccontent = 'print "hello,world"'
func += funccontent
evalcode = compile(func, '', 'eval')
exec (evalcode)
eval("%s" % funcname)
执行后编译错误：
eval_code = compile(func, '', 'eval')
File "", line 1
def func():
^
SyntaxError: invalid syntax
报错后使用 exec ：
funcname = "func"
func = "def %s():\n" % funcname
funccontent = 'print "hello,world"'
func += funccontent
evalcode = compile(func, '', 'exec')
exec (evalcode)
eval("%s" % funcname)
执行后编译错误：
Traceback (most recent call last):
File "/tmp/417881432/main.py", line 5, in <module>
evalcode = compile(func, '', 'exec')
File "", line 2
print "hello,world"
^
IndentationError: expected an indented block
exit status 1
修改缩进
funcname = "func"
func = "def %s():\n" % funcname
funccontent = ' print "hello,world"'
func += funccontent
evalcode = compile(func, '', 'exec')
exec (evalcode)
eval("%s" % funcname)
运行成功
