title: Reading EXIF data of a jpeg using python
body: <p>I'm trying to create a program to get specific EXIF information of a jpeg without using PIL and such. I'm reading the file in binary but the output is slightly confusing...</p>
  
  <pre><code>file = open("/Users/Niko/Desktop/IMG.JPG", "rb")
  print(file.read(16))
  </code></pre>
  
  <p>Which outputs:</p>
  
  <pre><code>b'\xff\xd8\xff\xe1/\xfeExif\x00\x00MM\x00*\x00\x00\x00\x08\x00\x0b\x01\x0f\x00\x02\x00\x00\x00\x06\x00\x00'
  </code></pre>
  
  <p>What I'm confused about is what the "\","/", and "*" mean...
  I know that the first few bytes that signify its a jpeg is 0xFF 0xD8, so I take it the \s are 0s? Can anyone help me understand this?</p>
  
  <p>Apologies for any beginners mistakes, new to coding in general and kind of just jumped in to creating this program.</p>
