IndentationError: 意外缩进 Python timeit() 方法

Question

当我学习时间复杂性概念时，我是 python 新手，了解了 time() 和 timeit() 方法。当我试图执行下面的程序时，得到一个错误“IndentationError: unexpected indent”。有人能说明一下这里到底是什么问题吗

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

你的缩进有点错误

代替：

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)}")
