[英]Convert list into a list of 2-tuples
I have a list: 我有一个清单:
list = [1, 2, 3]
I want to get this list and add a tuple so this list becomes like this 我想得到这个列表并添加一个元组,所以这个列表就像这样
T_list = [(1,x), (2, x), (3,x)]
How do I do it? 我该怎么做?
Use a simple list comprehension to do this: 使用简单的列表理解来执行此操作:
>>> your_list = [1, 2, 3]
>>> x = 100
>>> your_list_with_tuples = [(k, x) for k in your_list]
>>> your_list_with_tuples
Output 产量
[(1, 100), (2, 100), (3, 100)]
Also, don't name your variables list
, dict
, etc, because they shadow the builtin types/functions. 另外,不要将变量
list
, dict
等命名,因为它们会影响内置类型/函数。
A list comprehension would do the trick: 列表理解可以解决这个问题:
t_list = [(y,x) for y in original_list]
Also, the commenter is right. 此外,评论者是对的。 Don't name your lists
list
. 不要列出您的列表
list
。 It's a built in function. 它是内置功能。 Using it for something else could cause problems down the line.
将它用于其他事情可能会导致问题。
Here's my attempt, although I'm not an expert. 这是我的尝试,虽然我不是专家。
lis = [1,2,3]
tup = (4, 5, 6)
new_tup = tuple(lis)
new_lis = []
for i in range(0,3):
data = (new_tup[i],tup[i])
new_lis.append(data)
print(new_lis)
