convert_to_byte_array函数接受一个文件路径作为参数,打开文件并读取内容,然后将内容转换为字节数组并返回。save_byte_array函数接受一个字节数组和一个文件路径作为参数,将字节数组写入到文件中。 在主程序中,我们首先调用convert_to_byte_array函数将image.jpg文件的内容转换为字节数组,并将结果保存在byte_array变量中...
Thebytearray()method returns a bytearray object which is anarrayof the given bytes. Example prime_numbers = [2,3,5,7] # convert list to bytearraybyte_array = bytearray(prime_numbers) print(byte_array)# Output: bytearray(b'\x02\x03\x05\x07') bytearray() Syntax The syntax ofbytear...
The optional source parameter can be used to initialize the array in a few different ways: If it is a string, you must also give the encoding (and optionally, errors) parameters; bytearray() then converts the string to bytes using str.encode(). If it is an integer, the array will ha...
Write a Python program to create a bytearray from a given list of integers.Sample Solution:Code:def bytearray_from_list(int_list): byte_array = bytearray(int_list) return byte_array def main(): try: nums = [72, 123, 21, 108, 222, 67, 44, 38, 10] byte_array_result = ...
Now that we have covered how to convert the most common type of data, i.e. integers to ByteArrays, next let us address the 2nd most common datatype: “Strings”! Storing a String When working with strings we can use the following syntax to create the byte array from a string. ...
If it is astring, you must also give theencoding(and optionally,errors) parameters;bytearray()then converts the string to bytes usingstr.encode(). If it is aninteger, the array will have that size and will be initialized with null bytes. ...
Convert a bytes to bytearray >>> #create a bytes object from a list of integers in the range 0 through 255 >>> x = bytes([105, 100, 107, 112, 132, 118, 107, 112, 200]) >>> print(x) b'idkp\x84vkp\xc8' >>> #generates a new array of bytes from a bytes object ...
# Convert the byte string to a string using the decode() method decoded_string = byte_string.decode("utf-8") # Print the decoded string print(decoded_string) 在此示例中,我们定义一个字节字符串,并使用具有 UTF-8 字符编码的方法将其转换为字符串。生成的解码字符串是 ,然后将其打印到控制台。b...
