Create a CLI dictionary lookup

Here’s a simple Python script for a CLI dictionary lookup tool. It uses an online dictionary API (Free Dictionary API) to fetch word meanings, definitions, examples, and synonyms.

python
CopyEdit
import requests
import sys

def lookup_word(word):
    url = f"https://api.dictionaryapi.dev/api/v2/entries/en/{word}"
    response = requests.get(url)
    
    if response.status_code != 200:
        print(f"No definitions found for '{word}'.")
        return
    
    data = response.json()
    for entry in data:
        print(f"Word: {entry.get('word')}")
        
        meanings = entry.get('meanings', [])
        for meaning in meanings:
            part_of_speech = meaning.get('partOfSpeech', 'N/A')
            print(f"nPart of Speech: {part_of_speech}")
            definitions = meaning.get('definitions', [])
            for i, definition in enumerate(definitions, 1):
                print(f"  Definition {i}: {definition.get('definition')}")
                example = definition.get('example')
                if example:
                    print(f"    Example: {example}")
                synonyms = definition.get('synonyms', [])
                if synonyms:
                    print(f"    Synonyms: {', '.join(synonyms)}")
        print("n" + "-"*50 + "n")

def main():
    if len(sys.argv) < 2:
        print("Usage: python dict_lookup.py <word>")
        return
    
    word = sys.argv[1]
    lookup_word(word)

if __name__ == "__main__":
    main()

How to use:

1. Save this as dict_lookup.py.

2. Run in the terminal:

   arduino
   CopyEdit
   python dict_lookup.py <word>
   

   Replace <word> with the word you want to look up.

If you want, I can help you build a version that works offline or includes additional features like pronunciation or multiple languages.
