with open(’test.txt’, ‘w’) as file: file.write(‘Hello, world!’) 1. 2. 要写入特定编码的文本文件,请给open()函数传入encoding参数,将字符串自动转换成指定编码 字符编码 要读取非UTF-8编码的文本文件,需要给open()函数传入encoding参数,例如,读取GBK编码的文件: file= open(’gbk.txt’, ‘r...
f= open('/path/to/file','r')print(f.read())finally:iff: f.close() 但是每次都这么写实在太繁琐,所以,Python引入了with语句来自动帮我们调用close()方法: with open('/path/to/file','r') as f:print(f.read()) 这和前面的try ... finally是一样的,但是代码更佳简洁,并且不必调用f.close()...
>>> f = open('E:\python\python\gbk.txt', 'r', encoding='gbk', errors='ignore') 二进制文件 前面讲的默认都是读取文本文件,并且是UTF-8编码的文本文件。要读取二进制文件,比如图片、视频等等,用'rb'模式打开文件即可: >>> f = open('E:\python\python\test.jpg', 'rb') >>> f.read() ...

使用pyinstaller 打包exe总是失败, with open(src_path, 'rb') as fp: FileNotFoundError: [Errno 2] No such file or directory: 'd:\\Python\\python-3.7.9\\python37.zip\\struct.pyc' ,解决不了这个问题,试了N多办法,心瑟瑟。解决方法: ...
try:f=open('/path/to/file','r')print(f.read())finally:iff:f.close() 2.推荐方式:读取文件—–With Open 1).读取方式 每次如果都按照如上最终方案去写的话,实在太繁琐。Python引入了with语句来自动帮我们调用close()方法重点:!!!with 的作用就是自动调用close()方法 !!!
You can send any file via post api while calling the API just need to mention files={'any_key': fobj} import requests import json url = "https://request-url.com" headers = {"Content-Type": "application/json; charset=utf-8"} with open(filepath, 'rb') as fobj: response = requests...
with open("a.dat","rb") as f: In my opinion, if I use the first one, I must call f.close() function, while the second method need not. Am I right? Or there would be better method? Which one is the best to open a file in python? Thanks;-) python Share Improve this ...
