def count_letter(list):
    counter = 0
    maximal = 0
    word = ""
    for e in list:
        counter = e.count("i")
        if counter > maximal:
            maximal = counter
            word = e
    return word

word_list = ['box', 'computer', 'sheep', 'family', 'illegal', 'bubble', 'lamp', 'circuit', 'building', 'plant', 'these', 'cup']
print(count_letter(word_list))
