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 separator standard for your platform; e....
我们采用方案 B 来实现这一功能: defsave_string_to_binary_file(filename,string):withopen(filename,"wb")asf:f.write(string.encode())save_string_to_binary_file("output.dat","Hello, world!") 1. 2. 3. 4. 5. 为了验证解决方案的有效性,我们可以设置一些单元测试用例。 验证测试 在验证过程中,...

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, "hello.bin") with open(filename, "wb") as f: f.write("helloworld".encode("utf-8")) with open(f...

Any convenient ways if I can obtained a hex string, and want to convert it back to binary format?Yes, you just need to import binascii import binascii hs="5B7F888489FEDA" hb=binascii.a2b_hex(hs) file.write(hb) file.close()

importsys# 读取标准输入数据data=sys.stdin.buffer.read()# 将数据写入二进制文件withopen('output.bin','wb')asfile:file.write(data) 上述代码中,我们首先导入了sys模块,然后使用sys.stdin.buffer.read()方法读取标准输入的二进制数据,并将其存储在变量data中。
