步骤1:打开二进制文件 # 打开二进制文件,'rb'表示以二进制读取模式打开文件withopen('binary_file.bin','rb')asf: 1. 2. 步骤2:读取二进制数据 # 读取二进制数据binary_data=f.read() 1. 2. 步骤3:将二进制数据解码为文本数据 # 解码二进制数据为文本数据,使用utf-8编码text_data=binary_data.decode(...
在以二进制模式打开的文件上的f.read()返回一个bytes对象,该对象的行为就像一个可迭代的字节序列(文档)。 将f-string与{ :08b}格式说明符一起使用是将字节输出为字符串的一种方便方法。 import os import tempfile with tempfile.TemporaryDirectory() as temp_dir: filename = os.path.join(temp_dir, "he...

FTP.storbinary(command, file[, blocksize, callback, rest]) 二进制传输方式存储文件。command是适当的STOR命令:"STOR filename"。file是打开的文件对象,可以使用其read()方法读取blocksize的数据直到EOF。blocksize默认为8192。2.6版本:callback添加。2.7版本:rest添加。

If you choose to read the file a little at a time, rather than all at once, the idioms are different. Here’s how to read a binary file 100 bytes at a time, until you reach the end of the file: file_object = open('abinfile', 'rb') while 1: chunk = file_object.read(100...
