import time
def foo():
print("foo....")
time.sleep(1)
def bar():
print("bar>>>")
time.sleep(2)
def timea(x):
starttime = time.time()
x()
overtime = time.time()
print("spend %s"%(overtime -starttime))
timea(foo)
timea(bar)
老板说，增加个time统计功能，好了，timea模块写完了~~~~~~~~~~~~
老板又说，其他员工投诉了，你改了调用方式，其他的程序都要重新写啊...
经过第二课时的学习，知道了，内存地址，用return 返回内存地址，然后赋值给原来的参数，那么，问题解决了！
import time def foo(): print("foo....") time.sleep(1) def bar(): print("bar>>>") time.sleep(2) def timea(x): def inner(): starttime = time.time() x() overtime = time.time() print("spend %s" % (overtime - starttime)) return inner foo = timea(foo) bar = timea(bar) foo() bar()
import time def timea(x): def inner(): starttime = time.time() x() overtime = time.time() print("spend %s" % (overtime - starttime)) return inner @timea def foo(): print("foo....") time.sleep(1) @timea def bar(): print("bar>>>") time.sleep(2) foo() bar()
后来老师又讲了很高大上的@方法，将“@”放到def的上表面就可以了， @timea 代表了 fo0= timea(foo)
