This looks like quoted-printable encoding, which is used in email. Your Python source code should not be quoted-printable encoded, so you need to decode this either manually, by getting the source again without the encoding, or by using a decoder.
As you can see from the example on Wikipedia, =3D
decodes to =
. You can also verify this by evaluating chr(int('3D', 16))
in Python, which interprets 3D
as a hexadecimal value (base 16), and finds the ASCII character represented by that number.
