使用python装饰器验证配置文件示例

def VerifyInt(data):
assert(int(data) > 0)

def VerifyString(data):
assert(len(data) > 10)

def inner(*args, **kvargs):

print args
print kvargs

assert(len(args) > 1)
if args[1] == "int.txt":
VerifyInt(args[0])
elif args[1] == "string.txt":
VerifyString(args[0])

func(*args, **kvargs)

return inner

@VerifyData
def WriteData(text, filepath):
print "WriteData"
print text
print filepath

WriteData("1234567890", "int.txt")
