Python如何从文本文件制作可执行文件

Question

So what i want to do is write a .exe bynary to a .txt file and then write the .txt file to a .exe bynary, i tried this:

with open("old_File.exe", "rb") as f:
    text_file = open("File.txt", "w")
    byte = f.read(1)
    while byte != "":
        text_file.write(str(byte))
        byte = f.read(1)
text_file.close()

with open("New_File.exe", "wb") as f:
    text_file = open("File.txt", "r")
    byte = text_file.read(12)
    while byte != "":
        print byte
        f.write(byte)
        byte = text_file.read(12)
text_file.close()
f.close()

but if i run the New_File.exe windows tels me it is not a valid aplication. What am doing wrong?

Answer 1

The answer is:

The second time you were reading the *.txt file, you didn't open it in read binary mode, just in read, which is in fact, read text mode. With older versions of Python it was platform dependent, ie this will be a problem only on Windows. In Python 3, this will make you a problem on any platform.

Advice: Don't read a file in so small chunks if you don't have to, you will throttle poor Windows. Do it with at least 1024. It's often done with 4096 bytes. If the file is small, just do newfile.write(oldfile.read()) Todays PCs have enough RAM to put few MB in it without any problem. And, there is no need for str(byte) as it is already a string.

Answer 2

To copy two files and preserve metadata, use shutil.copy2 . This is a much safer way to copy files.

Answer 3

i foud the answer myself:

exe = open("exe.exe", "rb")
txt = open("txt.txt", "wb")
data = exe.read(100000)
while data != "":
    txt.write(data)
    data = exe.read(100000)
exe.close()
txt.close()

you actually have to write the binary on the text file instead of writing it as a string on the file itself.

    #create new file
N_exe = open("N-exe.exe", "w+")
N_exe.close()


N_exe = open("N-exe.exe", "wb")
Txt = open("txt.txt", "rb")

data = Txt.read(100000)
while data != "":
    N_exe.write(data)
    data = Txt.read(100000)

N_exe.close()
Txt.close()
