#key# Base64:https://riptutorial.com/python/topic/8678/the-base64-module #key# coding refers to encoding data from binary to text. This translates binary data to a radix-64 format in order to represent binary data in an ASCII string format.

There are many methods that are part of the Python `base64` module. **`base64.a85decode`** is one of the methods of the base64 library. We use `a85decode` to decode an a85encoded binary string into its normal form using Ascii85 alphabets.

# Syntax
```
base64.a85decode(b, foldspaces=False, adobe=False, ignorechars=b'\t\n\r\v')	 
```
1. `b`: A bytes-like object.

2. `foldspaces`: If `True`, the 4 consecutive spaces will be replaced by a character `y`. 

5. `adobe`: If `True`, the encoded string is written in between `<~` and `~>`.

4. `ignorechars`: The characters to be ignored in the encoding process. 

> The parameters do not have a significant impact when `False`.


import base64

# Data
data = "Welcome to Educative"
print("data:", data)
# converting the data to bytes-form
data_bytes = data.encode("UTF-8")
# perform the a85 encode function
result = base64.a85encode(data_bytes)
# set adobe to True
result1 = base64.a85encode(data_bytes, adobe = True)
print("a85encoded: ", result)
print("with adobe", result1)

## We can use a85decode function to decode.
# reverse of string with adobe set to False.
result2 = base64.a85decode(result)
print("a85decoded: ", result2)

# reverse of string with adobe set to True.
result3 = base64.a85decode(result1, adobe = True)
print("a85decoded: ", result3)
