Python sorted（）在windows系统上获取语法错误

我通过youtube学习并复制了这段代码，自己尝试，但无法复制结果，我使用windows系统和Atom编写代码，观看的视频是使用MAC系统和sublime，这会让它有所不同吗

s_employees=sorted[employees，key=attrgetter'age'] ^ SyntaxError:无效语法 [在0.141s中完成]

更改为s_employees=sortedemployees，key=attrgetter'age'

在花式attrgetter语法糖之前，让我们尝试一下：

class Employee():
def __init__(self, name, age, salary):
    self.name = name
    self.age = age
    self.salary = salary

def __repr__(self):
    return '({},{},${})'.format(self.name, self.age, self.salary)


from operator import attrgetter

e1 = Employee('Carl', 37, 70000)
e2 = Employee('Kevin', 30, 80000)
e3 = Employee('Rose', 25, 90000)

employees = [e1, e2, e3]

s_employees = sorted[employees, key = attrgetter('age')]

print(s_employees)

接下来，您可以将lambda调用替换为：

s_employees = sorted(employees, key = lambda employee: employee.age)

尽管如此，我还是会重写Employee类以使用/继承collections.namedtuple

函数调用使用foo…，而不是foo[…]。投票结束，因为简单的印刷错误。它的括号用于分类的员工，key=attrgetter'age'wow！谢谢我真不敢相信我犯了这个错误！

from operator import attrgetter
s_employees = sorted(employees, key = attrgetter('age'))

from collections import namedtuple
Employee = namedtuple("Employee",("name", "age", "salary"))
