In your code, the mmdc function is called twice - during validation and rendering. How can you optimize the code so that the utility is called only once?

Calling the mmdc function twice — during validation and rendering — can be inefficient, especially if mmdc is a heavy utility.

To optimize, you can call mmdc once, save the result, and reuse it. For example:

# Assume mmdc returns a processed result
result = mmdc(input_data)  # call once

# Validation
is_valid = validate(result)

# Rendering
render(result)

If mmdc is a function that transforms input data, you can apply memoization or caching of the result so that repeated calls with the same parameters return the stored result.

Example of memoization using functools:

from functools import lru_cache

@lru_cache(maxsize=None)
def mmdc_cached(input_data):
    return mmdc(input_data)

# Use mmdc_cached instead of mmdc
result = mmdc_cached(input_data)
# Then validation and rendering
