binary_data=text_content.encode() 1. 创建二进制文件 使用open()函数创建一个二进制文件,指定文件路径和打开模式为二进制写入模式。 withopen('binary_file.bin','wb')asbinary_file:# 在此处写入二进制数据到文件 1. 2. 将二进制数据写入文件 使用write()函数将二进制数据写入二进制文件。 binary_file.wri...
然后,我们需要将读取的二进制内容解码为文本内容。 #解码二进制内容为文本内容text_content = binary_content.decode('utf-8') 1. 2. 步骤4:写入文本文件 最后,我们将解码后的文本内容写入文本文件。 #将文本内容写入文本文件with open(text_file_path, 'w') as text_file: text_file.write(text_content) ...

You shouldjust write your string: somestring ='abcd'withopen("test.bin","wb")asfile: file.write(somestring) There is nothing magical about binary files; the only difference with a file opened in text mode is that a binary file will not automatically translate\nnewlines to the line separat...
can be performed on the file according to the opening mode. Note that when the file is opened as a text file, read and write in string mode, using the encoding used by the current computer or the specified encoding; When the file is opened in binary format, the read and write mode ...
