Мамакин Ярослав, А-02-23



\## 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()))
\\\['Mod1', '\\\_\\\_future\\\_\\\_', '\\\_\\\_main\\\_\\\_', '\\\_abc', '\\\_ast', '\\\_bisect', '\\\_bz2', '\\\_codecs', '\\\_collections', '\\\_collections\\\_abc', '\\\_colorize', '\\\_compat\\\_pickle', '\\\_compression', '\\\_datetime', '\\\_frozen\\\_importlib', '\\\_frozen\\\_importlib\\\_external', '\\\_functools', '\\\_heapq', '\\\_imp', '\\\_io', '\\\_lzma', '\\\_opcode', '\\\_opcode\\\_metadata', '\\\_operator', '\\\_pickle', '\\\_pyrepl', '\\\_pyrepl.pager', '\\\_queue', '\\\_random', '\\\_signal', '\\\_sitebuiltins', '\\\_socket', '\\\_sre', '\\\_stat', '\\\_string', '\\\_struct', '\\\_sysconfig', '\\\_thread', '\\\_tkinter', '\\\_tokenize', '\\\_typing', '\\\_warnings', '\\\_weakref', '\\\_weakrefset', '\\\_winapi', '\\\_wmi', 'abc', 'ast', 'bdb', 'binascii', 'bisect', 'builtins', 'bz2', 'codecs', 'collections', 'collections.abc', 'configparser', 'contextlib', 'copyreg', 'datetime', 'dis', 'encodings', 'encodings.aliases', 'encodings.cp1251', 'encodings.utf\\\_8', 'enum', 'errno', 'fnmatch', 'functools', 'genericpath', 'heapq', 'idlelib', 'idlelib.autocomplete', 'idlelib.autocomplete\\\_w', 'idlelib.calltip', 'idlelib.calltip\\\_w', 'idlelib.config', 'idlelib.debugger', 'idlelib.debugger\\\_r', 'idlelib.debugobj', 'idlelib.debugobj\\\_r', 'idlelib.hyperparser', 'idlelib.iomenu', 'idlelib.macosx', 'idlelib.multicall', 'idlelib.pyparse', 'idlelib.rpc', 'idlelib.run', 'idlelib.scrolledlist', 'idlelib.stackviewer', 'idlelib.tooltip', 'idlelib.tree', 'idlelib.util', 'idlelib.window', 'idlelib.zoomheight', 'importlib', 'importlib.\\\_abc', 'importlib.\\\_bootstrap', 'importlib.\\\_bootstrap\\\_external', 'importlib.machinery', 'importlib.util', 'inspect', 'io', 'ipaddress', 'itertools', 'keyword', 'linecache', 'lzma', 'marshal', 'math', 'nt', 'ntpath', 'opcode', 'operator', 'os', 'os.path', 'pickle', 'pkgutil', 'platform', 'plistlib', 'posixpath', 'pydoc', 'pyexpat', 'pyexpat.errors', 'pyexpat.model', 'queue', 'random', 're', 're.\\\_casefix', 're.\\\_compiler', 're.\\\_constants', 're.\\\_parser', 'reprlib', 'select', 'selectors', 'shlex', 'shutil', 'site', 'socket', 'socketserver', 'stat', 'string', 'struct', 'sys', 'sysconfig', 'tempfile', 'textwrap', 'threading', 'time', 'tkinter', 'tkinter.constants', 'token', 'tokenize', 'traceback', 'types', 'typing', 'urllib', 'urllib.parse', 'warnings', 'weakref', 'winreg', 'xml', 'xml.parsers', 'xml.parsers.expat', 'xml.parsers.expat.errors', 'xml.parsers.expat.model', 'zipimport', 'zlib']

Mod1.perm1

sys.modules.pop('Mod1')
<module 'Mod1' from 'C:\\\\Users\\\\uprkt\\\\Desktop\\\\ПО\\\\python-labs\\\\TEMA8\\\\Mod1.py'>

\## 2.3 Запуск модуля на выполнение с помощью функции exec()



```py
>>> exec(open('Mod1.py').read())
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
>>> perm1
'8'
```



\## 2.4

\## 3 Создание многомодульных программ



\## 3.1 Пример простой многомодульной программы



```py
>>> sys.modules.pop('Mod1')
<module 'Mod1' from 'C:\\\\Users\\\\uprkt\\\\Desktop\\\\ПО\\\\python-labs\\\\TEMA8\\\\Mod1.py'>
>>> sys.modules.pop('Mod2')
<module 'Mod2' from 'C:\\\\Users\\\\uprkt\\\\Desktop\\\\ПО\\\\python-labs\\\\TEMA8\\\\Mod2.py'>
>>> import Mod0
Mod1:Введите значение = 7
Mod1:Значение perm1= 7
perm1= 7
\*\*\*\*ALPHA\*\*\*\*
Значение t=8
tt= 8
qq= 82226315585.59491
>>> Mod0.tt;Mod0.qq;Mod0.Mod1.perm1
'8'
82226315585.59491
'7'
```



\## 3.2 Пример 2



Модуль ММ2:

```py

znach=input('k1,T,k2,Xm,A,F,N=').split(',')

k1=float(znach\[0])

T=float(znach\[1])

k2=float(znach\[2])

Xm=float(znach\[3])

A=float(znach\[4])

F=float(znach\[5])

N=int(znach\[6])



import math

vhod=\[]

for i in range(N):

&nbsp;	vhod.append(A\*math.sin((2\*i\*math.pi)\*F))



import MM1 as mod

yi1=0;yin1=0;yi2=0

vyhod=\[]

for xt in vhod:

&nbsp;	xt1=xt-yi2   #отрицательная обратная связь

&nbsp;	\[yi1,yin1]=mod.realdvig(xt1,k1,T,yi1,yin1)

&nbsp;	yi2=mod.tahogen(yin1,k2,yi2)

print('y=',MM2.vyhod)

```
