属性错误:模块“时间"在 Python 3.8 中没有属性“时钟" [英] AttributeError: module 'time' has no attribute 'clock' in Python 3.8

问题描述

我已经编写了代码来生成公钥和私钥.它在 Python 3.7 上运行良好，但在 Python 3.8 中失败.我不知道它在最新版本中是如何失败的.帮我解决一些问题.

I have written code to generate public and private keys. It works great at Python 3.7 but it fails in Python 3.8. I don't know how it fails in the latest version. Help me with some solutions.

代码如下:

from Crypto.PublicKey import RSA


def generate_keys():
    modulus_length = 1024
    key = RSA.generate(modulus_length)
    pub_key = key.publickey()
    private_key = key.exportKey()
    public_key = pub_key.exportKey()
    return private_key, public_key


a = generate_keys()
print(a)

Python 3.8 版本中的错误:

Error in Python 3.8 version:

推荐答案

来自 Python 3.8文档:

函数 time.clock() 已被删除，自 Python 3.3 起已被弃用:使用 time.perf_counter() 或 time.process_time() 相反，根据您的要求，具有明确定义的行为.(由 Matthias Bussonnier 在 bpo-36895 中贡献.)

The function time.clock() has been removed, after having been deprecated since Python 3.3: use time.perf_counter() or time.process_time() instead, depending on your requirements, to have well-defined behavior. (Contributed by Matthias Bussonnier in bpo-36895.)
