Python 3 - 如何更新字典以在一个键中包含多个值？

Question

employeenum = int(input("How many employees? "))
employee ={}
namelist = []
salarylist = []
jobname = []
profile = []
for i in range (0,employeenum):
    job1 = input("Please enter the job's name here: ").lower()
    name1 = input("Please enter the employee's name here: ")
    salary1 = int(input("Please enter the employee's salary here: "))
    jobname.append(job1)
    print(jobname)
    namelist.append(name1)
    salarylist.append(salary1)
    profile.append([{'Name': namelist[i], 'Salary': salarylist[i]}])
    employee.update({jobname[i]: profile[i]})
    employee[jobname[i]].append(profile[i])
    print(employee)
    print(profile)
print(employee)
# {'Programmer': [{'Name': 'Tim', 'Salary': 65000}, {'Name': 'Sally', 'Salary': 50500}], 'Part Time Manager': [{'Name': 'Bob', 'Salary': 17500}]}

大家好，我的代码有问题，因为我正在尝试打印一个字典，该字典将以 worker 的工作名称为键，值将是他们的姓名和薪水(所需的输出是最后一行注释在上面的代码中)。我遇到了一个问题，如果两个或更多人拥有相同的工作，它将覆盖前一个人的个人资料。因此，如果 John 和 Nick 都是护士，则只会显示 Nick 的个人资料，因为他是用户最后输入的。在此先感谢您的帮助!

尝试以下操作，或者您可以查看 defaultdict:

employeenum = int(input("How many employees? "))
employee ={}

for i in range (0, employeenum):

    job1 = input("Please enter the job's name here: ").lower()
    name1 = input("Please enter the employee's name here: ")
    salary1 = int(input("Please enter the employee's salary here: "))

    new_entry = {"Name": name1, "Salary": salary1}
    if job1 in employee:
        employee[job1].append(new_entry)
    else:
        employee[job1] = [new_entry]
