如何从嵌套字典中打印多个值？

Question

我的作业问题之一是使用嵌套字典在一行上打印。我怎样才能做到这一点？

Answer 1

for employee in employees:    if employee["title"] == "Mr":        print(employee["employee_id"])        print(employee["lastname"], employee["firstname"])

Answer 2

您可以使用 的多个参数print用空格分隔它们（可以用sep参数更改）：print(employees[0]["employee_id"], employees[1]["employee_id"])但是，如果您想打印出所有男性员工的 ID，您有几个不同的选择：for 环形：for employee in employees:    if employee["title"] == "Mr":        print(employee["employee_id"], end=" ")参数解包：male_employees = [employee["employee_id"] for employee in employees if employee["title"] == "Mr"]print(*male_employees)str.joinmale_employees = [employee["employee_id"] for employee in employees if employee["title"] == "Mr"]print(" ".join(male_employees))特别是对于家庭作业问题，使用for循环的第一个选项是最直观的。编辑：要打印名称，您可以使用格式字符串：for employee in employees:    if employee["title"] == "Mr":        print("{0}, {1}".format(employee["lastname"], employee["firstname"]), end=" ")如果你想玩得更开心，这是一个选择：for employee in employees:    if employee["title"] == "Mr":        print("{lastname}, {firstname}".format(**employee), end=" ")
