This video is not at all about reading a binary file. It's about reading a text file which contains only the characters '0'' and '1' and treating it as if it were binary, which it clearly is not.

Can you make a tutorial on stdin, stdout, stderr

why i am not getting the output, First i converted the text file to binary and after getting the binary output i saved it in text file again
and trying to get the string back .
Here is my code:

f = open("mydjangonotes.txt", "r+")

test_str = f.read()

#print("The original string is : " + str(test_str))

res = ''.join(format(ord(i), 'b') for i in test_str)

bin_d = str(res)

#print("The string after binary conversion : ", bin_d )

f.truncate(0)

f.seek(0)

f.write(bin_d)

f.close()



f = open("mydjangonotes.txt", "r")

text = f.read()

print("value-", text)

f.close()



with open('mydjangonotes.txt', 'r') as f:

data = f.read(8)



while data!= '':

plaintext = chr(int(data, 2))

print(plaintext, end="")

data=f.read(8)
