将相同的变量添加到元组列表中 [英] adding the same variable to a list of tuples

问题描述

我有以下 3 个列表和一个值 (country[i])，我想将相同的 country[i] 添加到所有可用的元组中:

name = ["a", "b", "c"]年龄 = [1, 2, 3]city = ["aaa", "bbb", "ccc"]国家[i]

其中 country[i] 等于美国"，我使用了以下代码:

user_info = [tuple((t,)) for t in zip(name, age, city, country[i])]

执行时我得到以下结果:

[(('a', 1, 'aaa', 'U'),), (('b', 2, 'bbb', 'n'),), (('c', 3, 'ccc', 'i'),)]

虽然我想要的是:

[('a', 1, 'aaa', 'United States'), ('b', 2, 'bbb', 'United States'), ('c', 3, 'ccc'， '美国)]

解决方案

您可以手动"将其添加到每个项目中:

v = (country[i], )[t + v for t in zip(name, age, city)]

演示:

<预><代码>>>>国家 = [美国"]>>>我 = 0>>>名称 = ["a", "b", "c"]>>>年龄 = [1, 2, 3]>>>city = ["aaa", "bbb", "ccc"]>>>v = (国家[i], )>>>[t + v for t in zip(name, age, city)][('a', 1, 'aaa', '美国'), ('b', 2, 'bbb', '美国'), ('c', 3, 'ccc', '美国')]

I've the below 3 lists and a value (country[i]) and i want to add the same country[i] to all tuples available:

name = ["a", "b", "c"]
age = [1, 2, 3]
city = ["aaa", "bbb", "ccc"]
country[i]

where country[i] equals to "United States", And i used the following code:

user_info = [tuple((t,)) for t in zip(name, age, city, country[i])]

When executed i got the following result:

[(('a', 1, 'aaa', 'U'),), (('b', 2, 'bbb', 'n'),), (('c', 3, 'ccc', 'i'),)]

While what i want is:

[('a', 1, 'aaa', 'United States'), ('b', 2, 'bbb', 'United States'), ('c', 3, 'ccc', 'United States)]

解决方案

You can add it to each of the item "manually":

v = (country[i], )
[t + v for t in zip(name, age, city)]

Demo:

>>> country = ["United States"]
>>> i = 0
>>> name = ["a", "b", "c"]
>>> age = [1, 2, 3]
>>> city = ["aaa", "bbb", "ccc"]
>>> v = (country[i], )
>>> [t + v for t in zip(name, age, city)]
[('a', 1, 'aaa', 'United States'), ('b', 2, 'bbb', 'United States'), ('c', 3, 'ccc', 'United States')]
