+
+The **`binascii.b2a_base64()`** function encodes binary data into a Base64-encoded ASCII string, making it easier to transmit or store binary content such as images or files in text-based formats.
+
+## Syntax
+
+```pseudo
+binascii.b2a_base64(data, *, newline=True)
+```
+
+**Parameters:**
+
+- `data`: The binary data to encode.
+- `newline` (optional): If set to `False`, omits the trailing newline character. Default is `True`.
+
+**Return value:**
+
+Returns the Base64-encoded version of the input binary data as a bytes object.
+
+## Example
+
+In this example, binary data is encoded into a Base64-encoded bytes object using the default newline setting:
+
+```py
+import binascii
+
+# Original binary data
+binary_data = b'Hello, Hacktoberfest!'
+
+# Encoding with the default newline character
+encoded_data = binascii.b2a_base64(binary_data)
+
+# Printing the encoded data
+print(encoded_data)
+```
+
+The output of this code is:
+
+```shell
+b'SGVsbG8sIEhhY2t0b2JlcmZlc3Qh\n'
+```
+
+## Codebyte Example
+
+In this example, a short text is converted into its Base64-encoded representation, showing both the original and encoded data:
+
+```codebyte/python
+import binascii
+
+# The data to be encoded
+data_to_encode = b'Codecademy Docs!'
+
+# Perform Base64 encoding
+encoded_data = binascii.b2a_base64(data_to_encode)
+
+# Print the original and encoded data
+print(f"Original: {data_to_encode}")
+print(f"Encoded: {encoded_data}")
+```
