Hi, can you explain to me what this Python function does?

def rand_letters(width, height):
    
    field = []
    letters = [*'ABCDEFGHIJKLMNOPQRSTUVWXYZ']
    
    for i in range(height):
        row = [random.choice(letters) for j in range(width)]
        field.append(row)
        
    return numpy.array(field)
system
namaste, kya aap mujhe samajha sakate hai ki yah paythan fnction kya karata he?

DEF RAND_LETTERS (chaudaai, oonchai):
    
    kshetra = []
    patr = [*'abcdefghijklmnopqrstuvwxyz']]
    
    main range main (oonchai) ke liye:
        ROW = [random.chois (akshar) J ke liye range (chaudaai)]]
        field.append (pankti)
        
    Numpy.Array (field) lauten

bilkul!yah fnction kisi die gaye chaudaai or oonchai kaa do-aiami sarani banane kaa kaary karata he.sarani main prayek maan ek yadrichhik rup se chaynit capital letters he.is fnction kaa upyog karne ke liye, apane vaanchit ayaamon ke saath Rand_letters () chalaane kaa prayaas karen, or aapako yadrichhik rup se mishrit aksharon kaa ek varg matrix praapt hoga.aapako kaam karne ke liye yadrichhik modul or numpy modul ko bhi aayaat karne kii aavashyaktaa hogi kyonki yah yadrichhik ko kol karata he.
