零基础学python之file文件with open打开方式

1、# 首先定义路径存为变量path1 = r'D:\desk\1.txt'

2、# path1路径 w:只写打开文件 utf-8：以怎样的编码打开文件 as f：打开后接口存为fwith open(path1, 'w', encoding='utf-8') as f:    pass

3、with open(path1, 'w', encoding='utf-8') as f:    s = 'good.123.love.456.make'    f.write(s)    f.flush()  # 刷新缓冲区，类似于word中点击保存    f.seek(0)    f.write('dog')   # 代码执行后，会自动关闭文件。

4、with open(path, 'a', encoding='utf-8') as f:    f.write('ying')    f.flush()    f.seek(0)    f.write('love')

5、path = r'D:\desk\4.txt'with open(path, 'wb') as f:    s = 'good morning 水立方'    code = s.encode(encoding='utf-8')    f.write(code)

6、# 查看4.txtpath = r'D:\desk\4.txt'with open(path, 'r', encoding='utf-8') as f:    print(f.read())
