IndentationError: unexpected indent Python timeit() Method

Question

我是 python 的新手，当时正在学习时间复杂度概念，了解 time() 和 timeit() 方法。当我尝试执行下面的程序时出现错误 "IndentationError: unexpected indent"。有人可以阐明这里的问题吗

import timeit
setup_code = "from math import factorial"
 statement="""for i in range(10):
    factorial(i)"""   
 print(f"Execution time is: {timeit.timeit(setup = setup_code, stmt = statement, number = 10000000)}")

Answer 1

你的缩进有点不对

而不是：

import timeit
setup_code = "from math import factorial"
 statement="""for i in range(10):
    factorial(i)"""   
 print(f"Execution time is: {timeit.timeit(setup = setup_code, stmt = statement, number = 10000000)}")

尝试：

import timeit
setup_code = "from math import factorial"
statement="""for i in range(10):
   factorial(i)"""   
print(f"Execution time is: {timeit.timeit(setup = setup_code, stmt = statement, number = 10000000)}")
