For markdown inline code. Find the longest contiguous sequence of backticks in the string then wrap string with appropriate number of backticks required to escape it

escape_markdown_inline_code.py

def escape_markdown_inline_code(value_string):
    # Find the longest contiguous sequence of backticks in the string then
    # wrap string with appropriate number of backticks required to escape it
    max_backticks = max((len(match.group(0)) for match in re.finditer(r'`+', value_string)), default=0)
    inline_code_marker = '`' * (max_backticks + 1)

    # If the string starts or ends with a backtick, add a space at the beginning and end
    if value_string.startswith('`') or value_string.endswith('`'):
        value_string = f" {value_string} "

    return f"{inline_code_marker}{value_string}{inline_code_marker}"

This is the expected output.

>>> escape_markdown_inline_code("hello world")
'`hello world`'
>>> escape_markdown_inline_code("hello ` world")
'``hello ` world``'
>>> escape_markdown_inline_code("hello `` world")
'```hello `` world```'
>>> escape_markdown_inline_code("`hello world`")
'`` `hello world` ``'
