可以通过以下两种方式读取 .py 文件并导入自定义模块:使用 importlibimportlib 模块提供了 import_module() 函数,可动态导入文件,并返回指向导入模块的引用。 使用 open()open() 函数可打开文件并返回指向文件对象的引用,文件对象具有 read() 方法,可读取文件内容。

Python 教程:读取 .py 文件

导入必要的模块

import os
import importlib

使用 importlib

importlib 模块提供了一个 import_module() 函数,可动态导入文件。此方法返回指向导入模块的引用。

file_path = "my_module.py"
my_module = importlib.import_module(file_path)

使用 open()

open() 函数可打开文件并返回指向文件对象的引用。文件对象具有 read() 方法,可读取文件内容。

with open(file_path, "r") as f:
    file_contents = f.read()

实战案例:读取自定义模块

假设有一个名为 my_module.py 的自定义模块:

# my_module.py
def greet(name):
    print(f"Hello, {name}!")

现在,让我们从另一个脚本中读取此模块:

# main.py
import os
import importlib

file_path = "my_module.py"
my_module = importlib.import_module(file_path)

my_module.greet("John")

输出:

Hello, John!

Python: compiler or Interpreter?Python: compiler or Interpreter?May 13, 2025 am 12:10 AM

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
