如何读取文件，将二进制缓冲区转换为二进制字符串，然后在 python 中再次将二进制字符串转换为二进制缓冲区？

Question

I opened a file (.jpeg) in binary format and stored it's content in a variable and converted the binary buffer into string using str(). Now, I want to convert the string into binary buffer again.

from tkinter import filedialog
file_path = filedialog.askopenfilename()
file = open(file_path,"rb")
file_content = file.read()
file.close()
print(file_content)
file_content_str = str(file_content)
print(file_content)

# want a code to convert file_content_str into bytes again here
# file_content_bytes = file_content_string converted to bytes

# file2 = open("moon2.jpg", "w+b")
# file2.write(file_content_bytes)
# file2.close()

Answer 1

As much as I avoid eval, try this:

file_content_bytes = eval(file_content_str)
