<SYSTEM_TASK:>
Given the following text description, write Python code to implement the functionality described below step by step
<END_TASK>
<USER_TASK:>
Description:
Step1:  repeat(1,10000)重复一次，每次10000遍
Step2:  这个就没有重复多少次，就一次，一次10000遍
注意这里timeit.timeit的函数声明，第三个参数是timer，为了避过该参数，到了number这里，显式的声明该参数
<ASSISTANT_TASK:>
Python Code:
setup_sum='sum=0'
run_sum=
for i in range(1,1000):
    if i % 3 ==0:
        sum = sum + i
print(timeit.Timer(run_sum, setup="sum=0").repeat(1,10000))
Explanation: repeat(1,10000)重复一次，每次10000遍
End of explanation
t=timeit.timeit(run_sum,setup_sum,number=10000)
print("Time for built-in sum(): {}".format(t))
start=time.time()
sum=0
for i in range(1,10000):
    if i % 3==0:
        sum+=i
end=time.time()
print("Time for trading way to count the time is %f"%(end-start))
Explanation: 这个就没有重复多少次，就一次，一次10000遍
注意这里timeit.timeit的函数声明，第三个参数是timer，为了避过该参数，到了number这里，显式的声明该参数
