Python|从给定列表创建三元组的方法

给定一个单词列表，编写一个Python程序从给定列表创建三元组。

例子：

Input: [‘Geeks’, ‘for’, ‘Geeks’, ‘is’, ‘best’, ‘resource’, ‘for’, ‘study’]
Output:
[[‘Geeks’, ‘for’, ‘Geeks’], [‘for’, ‘Geeks’, ‘is’],
[‘Geeks’, ‘is’, ‘best’], [‘is’, ‘best’, ‘resource’],
[‘best’, ‘resource’, ‘for’], [‘resource’, ‘for’, ‘study’]]

Input: [‘I’, ‘am’, ‘Paras’, ‘Jain’, ‘I’, ‘Study’, ‘From’, ‘GFG’]
Output:
[[‘I’, ‘am’, ‘Paras’], [‘am’, ‘Paras’, ‘Jain’],
[‘Paras’, ‘Jain’, ‘I’], [‘Jain’, ‘I’, ‘Study’],
[‘I’, ‘Study’, ‘From’], [‘Study’, ‘From’, ‘GFG’]]

编程需要懂一点英语

让我们看看执行此任务的一些方法。

方法 #1：使用列表推导

# Python code to create triplets from list of words.
  
# List of word initialization
list_of_words = ['I', 'am', 'Paras', 'Jain',
                 'I', 'Study', 'DS', 'Algo']
  
# Using list comprehension
List = [list_of_words[i:i + 3] 
        for i in range(len(list_of_words) - 2)]
  
# printing list
print(List)

输出：

[['I', 'am', 'Paras'], ['am', 'Paras', 'Jain'], 
 ['Paras', 'Jain', 'I'], ['Jain', 'I', 'Study'],
 ['I', 'Study', 'DS'], ['Study', 'DS', 'Algo']]

方法#2：使用迭代

# Python code to create triplets from list of words.
  
# List of word initialization
list_of_words = ['Geeks', 'for', 'Geeks', 'is',
                 'best', 'resource', 'for', 'study']
  
# 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)

输出：

[['Geeks', 'for', 'Geeks'], ['for', 'Geeks', 'is'],
 ['Geeks', 'is', 'best'], ['is', 'best', 'resource'],
 ['best', 'resource', 'for'], ['resource', 'for', 'study']]
