对于列表列表上的循环

Question

我有一个列表，其中包含一些数据，我希望能够调用列表的内容，但只能调用某些内容，例如：empList[0][0]，empList[0][1]。我希望能够对列表中的每个项目执行此操作，然后从列表的该部分调用所选索引，例如：empList[0][0]、empList[0][1]、empList[1][0]、empList[1][1]，但在for循环中。 我的参考代码：

empList = [
    ['51-4678119', 'Issie', 'Scholard', '11 Texas Court', 'Columbia', 'Missouri', '65218', '3', '134386.51', '34', '91.06'],
    ['68-9609244', 'Jed', 'Netti', '85 Coolidge Terrace', 'San Antonio', 'Texas', '78255', '2', '159648.55', '47', '45.7'],
    ['47-2771794', 'Galvan', 'Solesbury', '3 Drewry Junction', 'Springfield', 'Illinois', '62794', '2', '91934.89', '39', '47.92']
]
emp = employee(empList[0][0], empList[0][1], empList[0][2], empList[0][3], empList[0][4], empList[0][5], empList[0][6], empList[0][7])

希望这是有道理的。谢谢大家!

Answer 1

您可以使用：

emp = employee(*empList[0][:8])

Answer 2

这可能类似于您正在寻找的：

from collections import namedtuple

empList = [
    ['51-4678119', 'Issie', 'Scholard', '11 Texas Court', 'Columbia', 'Missouri', '65218', '3', '134386.51', '34', '91.06'],
    ['68-9609244', 'Jed', 'Netti', '85 Coolidge Terrace', 'San Antonio', 'Texas', '78255', '2', '159648.55', '47', '45.7'],
    ['47-2771794', 'Galvan', 'Solesbury', '3 Drewry Junction', 'Springfield', 'Illinois', '62794', '2', '91934.89', '39', '47.92']
]
Employee = namedtuple('Employee', 'ID First Last Street City State Zip Ham Salary Eggs Spam')
employees = [Employee(*e) for e in empList]

print(employees[0])
print(employees[1].State)
print(employees[2].Ham)

Employee(ID='51-4678119', First='Issie', Last='Scholard', Street='11 Texas Court', City='Columbia', State='Missouri', Zip='65218', Ham='3', Salary='134386.51', Eggs='34', Spam='91.06')
Texas

Answer 3

如果参数的顺序始终正确，则可以执行以下操作：

employees = [employee(*args) for args in empList]
