with open("./aa.txt", "w+") as fp: fp.write("This is a text file.") print(fp.closed()) with open() as file则没有上述的问题,由上面代码可知,当with as代码块结束时,程序自动关闭打开的文件,不会造成系统资源的长期占用。 open()函数的几个常用参数: open("文件路径", "文件代开方式", ...

As I said in your previous question, there is no need to base64 encode the string, it will only make the program slower. Just use the repr >>> with open("images/image.gif", "rb") as fin: ... image_data=fin.read() ... >>> with open("image.py","wb") as fout: ... ...
defkill_captcha(data):withopen('captcha.png','wb')asfp:fp.write(data)returnraw_input('captcha : ') 然后,我们的思路是通过一个函数模拟上面分析的步骤登录知乎,返回登录成功的requests.Session对象,我们通过持有这个对象,来完成登录之后才能完成的事情。函数的实现如下: ...
