将 python 包导入 python 模块时出现 ImportError

Question

我创建了一个 python 包，即 package_demo，它有三个 python 模块init.py、employee.py 和 manager.py .

employee.py:-

def topSalary_employee(salary_list):
    return max(salary_list);

def leastSalary_employee(salary_list):
    return min(salary_list);

def avarageSalary_employee(salary_list):
    summation=0;
    for salary in salary_list:
        summation+=salary;
    return summation;

manager.py:-

def topSalary_manager(salary_list):
    return max(salary_list);

def leastSalary_manager(salary_list):
    return min(salary_list);

def avarageSalary_manager(salary_list):
    summation=0;
    for salary in salary_list:
        summation+=salary;
    return summation;

init.py:-

from manager import*;
from employee import*;

现在我想访问 manager.py 和 employee.py 的所有功能到另一个 python 模块即 AAA.py 位于包 package_demo 之外.这是 AAA.py

的代码

AAA.py:-

import package_demo

employee_salary_list = [12000,23000,18000,25000,8000,17000];
manager_salary_list = [32000,45000,28000,50000,38000,44000];

print("\t...Manager Salary Details...");
print("Highest salary of Manager : ",package_demo.topSalary_employee(manager_salary_list));
print("Lowest salary of Manager : ",package_demo.leastSalary_manager(manager_salary_list));
print("Average salary of Manager : ",package_demo.avarageSalary_manager(manager_salary_list));

print("\t...Employee Salary Details...");
print("Highest salary of Employee : ",package_demo.topSalary_employee(employee_salary_list));
print("Lowest salary of Employee : ",package_demo.leastSalary_employee(employee_salary_list));
print("Average salary of Employee : ",package_demo.avarageSalary_employee(employee_salary_list));

但是当我运行 AAA.py程序时，它会显示如下错误

Traceback (most recent call last):
  File "F:\Document\Files\Coding\Java Eclipse\Python Project\First Project\src\AAA.py", line 1, in <module>
    import package_demo
  File "F:\Document\Files\Coding\Java Eclipse\Python Project\First Project\src\package_demo\__init__.py", line 1, in <module>
    from manager import*;
ImportError: No module named 'manager'

Answer 1

所有导入都是从您在 Python 中启动的目录进行评估的，因此当 init.py 尝试导入管理器时 Python 将尝试从您当前所在的目录中查找而不是来自 init.py 所在的目录。

您想使用相对导入或将导入转换为绝对导入：

亲戚：

from .manager import*;
from .employee import*;

绝对值：

from package_demo.manager import*;
from package_demo.employee import*;
