|
## 1 Начало работы со средой и подключение необходимых модулей
|
|
|
|
|
|
```py
|
|
|
>>> import os,sys,importlib
|
|
|
>>> os.chdir(r'C:\Users\uprkt\Desktop\ПО\python-labs\TEMA8')
|
|
|
>>> os.getcwd()
|
|
|
'C:\\Users\\uprkt\\Desktop\\ПО\\python-labs\\TEMA8'
|
|
|
```
|
|
|
|
|
|
## 2 Создание и использование модулей в среде Python.
|
|
|
|
|
|
## 2.1 Запуск модуля на выполнение путем его импорта.
|
|
|
|
|
|
```py
|
|
|
>>> import Mod1
|
|
|
Mod1:Введите значение = 5
|
|
|
Mod1:Значение perm1= 5
|
|
|
>>> Mod1.perm1
|
|
|
'5'
|
|
|
>>> import Mod1
|
|
|
>>> importlib.reload(Mod1)
|
|
|
Mod1:Введите значение = 3
|
|
|
Mod1:Значение perm1= 3
|
|
|
<module 'Mod1' from 'C:\\Users\\uprkt\\Desktop\\ПО\\python-labs\\TEMA8\\Mod1.py'>
|
|
|
>>> Mod1.perm1
|
|
|
'3'
|
|
|
```
|
|
|
|
|
|
## 2.2 Словарь импортированных модулей
|
|
|
|
|
|
```py
|
|
|
>>> print(sorted(sys.modules.keys()))
|
|
|

## 2.3 Запуск модуля на выполнение с помощью функции exec()
|
|
|
|
|
|
```py
|
|
|

|
|
|
Mod1:Введите значение = 6
|
|
|
Mod1:Значение perm1= 6
|
|
|
>>> Mod1.perm1
|
|
|
'2'
|
|
|
>>> perm1
|
|
|
'6'
|
|
|
>>> exec(open('Mod1.py').read())
|
|
|
Mod1:Введите значение = 7
|
|
|
Mod1:Значение perm1= 7
|
|
|
>>> perm1
|
|
|
'7'
|
|
|
>>> exec(open('Mod1.py').read())
|
|
|
Mod1:Введите значение = 8
|
|
|
Mod1:Значение perm1= 8
|
|
|

'8'
|
|
|
```
|

Модуль ММ2:
|

```py
|
