Python - 從給定列表生成三元組的方法
列表是一種按順序排列且可更改的集合。在 Python 中,列表使用方括號書寫。透過引用索引號訪問列表項。負索引表示從末尾開始, -1 表示最後一項。你可以透過指定範圍的開始和結束位置來指定索引範圍。指定範圍時,返回值將是一個包含指定項的新列表。
示例
# triplets from list of words. # List of word initialization list_of_words = ['I', 'am', 'Vishesh', 'and', 'I', 'like', 'Python', 'programming'] # Using list comprehension List = [list_of_words[i:i + 3] for i in range(len(list_of_words) - 2)] # printing list print(List) # List of word initialization list_of_words = ['I', 'am', 'Vishesh', 'and', 'I', 'like', 'Python', 'programming'] # Output list initialization out = [] # Finding length of list length = len(list_of_words) # Using iteration for z in range(0, length-2): # Creating a temp list to add 3 words temp = [] temp.append(list_of_words[z]) temp.append(list_of_words[z + 1]) temp.append(list_of_words[z + 2]) out.append(temp) # printing output print(out)
