+
+In Python, the **`.a2b_qp()`** [function](https://www.codecademy.com/resources/docs/python/functions) decodes a string of quoted-printable data back to binary.
+
+Quoted-printable is an encoding scheme used in email messages to represent non-ASCII characters using only ASCII characters.
+
+## Syntax
+
+```pseudo
+binascii.a2b_qp(data, header=False)
+```
+
+**Parameters:**
+
+- `data`: A bytes-like object containing the quoted-printable encoded data to decode.
+- `header`: When set to `True`, it decodes the data as if it were in an email header, handling special rules for headers. Default is `False`.
+
+**Return value:**
+
+The `.a2b_qp()` function returns the decoded binary data as a bytes object.
+
+## Example
+
+This example decodes a quoted-printable encoded byte string into its original binary form:
+
+```py
+import binascii
+
+# Quoted-printable encoded data
+encoded_data = b'Codecademy=20Docs'
+
+# Decode the data back to binary
+decoded_data = binascii.a2b_qp(encoded_data)
+
+print(decoded_data)
+```
+
+This produces the following output:
+
+```shell
+b'Codecademy Docs'
+```
+
+## Codebyte Example
+
+This example decodes a quoted-printable encoded message body retrieved from an email:
+
+```codebyte/python
+import binascii
+
+# Quoted-printable encoded email message
+email_body = b'Hello=2C=20thank=20you=20for=20joining=20Codecademy=21'
+
+# Decode the email message body
+decoded_body = binascii.a2b_qp(email_body)
+
+print(decoded_body)
+```
