我们可以使用os.environ来读取env文件中的配置参数。下面是一个使用os.environ读取env文件的示例代码: AI检测代码解析 importos# 从.env文件中读取配置参数defread_env_file(file_path):withopen(file_path,'r')asfile:forlineinfile:line=line.strip()iflineandnotline.startswith('#'):key,value=line.split('...
除此之外,对于以二进制格式打开的文件,read() 函数会逐个字节读取文件中的内容。例如: #!/usr/bin/env python#-*- coding: utf-8 -*-__author__='tian'__data__='2024/12/16 15:03'#software: PyCharm#二进制形式打开指定文件f = open("new_my_file.txt","rb+")#输出读取到的数据print(f.rea...
// We cache the C environment. This means that subsequent calls // to putenv/setenv from C will not be visible from Java code. byte[][] environ = environ(); theEnvironment = new HashMap<>(environ.length/2 + 3); // Read environment variables back to front, // so that earlier var...

2.读取文本文件(readtext.py) 程序如下: #read and dislay text file print("read and dislay text file") fname = input("Enter filename:") print #display a empty line #attempt to open file for reading try: fobj = open(fname, 'r') except IOError: print("file open error:") else: #...
