The `binascii` is a widely used Python library for ASCII-encoded binary representations. It contains several methods to convert to binary from ASCII or hex, and vice versa. Most methods are not used directly, but wrapper modules such as `uu`, `base64`, or `binhex` are commonly used. 


**`binascii.b2a_uu`** is one of the many wrapper modules in the `binascii` library. It is used to convert data (in binary) to a line of ASCII characters. This means the ASCII characters are returned as a single line with a "\n" character at the end to indicate to new line character. 

# Syntax
```
binascii.b2a_uu(data, *, backtick=False)
```

# Parameters
1. `data`: The data that needs to be converted. The length of returned line should be 45 at most. 

2. `backtick`: This is used if a user wishes to replace the zeros with a '`'.

import binascii

text = "HeLLo WorLd"
text = bytes(text , 'utf-8')
data = binascii.b2a_uu(text)
text = binascii.a2b_uu(data)
print(str(text), "<=>", str(data))


What is binascii.b2a_uu in Python?

Converts binary data to ASCII-encoded strings, using backtick to replace zeros if desired.
