python读取文件with open

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())
