The **`binascii`** is a widely used Python library for ASCII-encoded binary representations. It contains several methods for converting to binary from ASCII or hex, and vice versa.



**[binascii.rledecode_hqx](https://docs.python.org/3/library/binascii.html)** is one of the methods of `binascii` library in Python. It is the opposite of `rlecode_hqx` method. 

We can use `binascii.rledecode_hqx` to perform RLE-decompression on data. We can use this method to decompress the data -- previously compressed by using Run length encoding format -- to original data.

The procedure is simple. While encoding the data, we use the method of #key# `rlecode_hqx`: Given an input, say “Heloooooooo”, the method  `rlecode_hqx` iterates through the string to check for consecutive characters. In this case, there are 8 consecutive “o’s”. This will be compressed and output will be shown with a single "o" followed by `\x90\x` and then the number of times it occurred. #key#.  `rledecode_hqx` identifies `\x90\x` in the compressed input to find the number of times a single character is present in the uncompressed string and the decompresses the compressed string by replacing the number of characters with the actual characters. 



## Syntax
```
binascii.rledecode_hqx(data)
```

## Code

Below are a few examples to illustrate the use of `binascii.rledecode_hqx`.

import binascii

# data in compressed format
# there is '\x90\x' after o.
# this is followed by a 07.
# This means there are a total of 7 o's
data = b'Hello\x90\x07W\x90\x06orld\x90\x04'

# perform the decoding of data
decompressed = binascii.rledecode_hqx(data)
print(decompressed)

# another example
data = b'Hi\x90\x04 Hello\x90\x04'

decompressed = binascii.rledecode_hqx(data)
print(decompressed)
