							|  |  | ## Изучение среды IDLE
 | 
						
						
						
							|  |  | ```py
 | 
						
						
						
							|  |  | >>> print('Hello') 
 | 
						
						
						
							|  |  | Hello
 | 
						
						
						
							|  |  | >>> h=input('Your name=')
 | 
						
						
						
							|  |  | Your name=Dima
 | 
						
						
						
							|  |  | >>>print(h)
 | 
						
						
						
							|  |  | Dima
 | 
						
						
						
							|  |  | >>> exit()
 | 
						
						
						
							|  |  | ```
 | 
						
						
						
							|  |  | ## Настройки рабочего каталога среды
 | 
						
						
						
							|  |  | ```py
 | 
						
						
						
							|  |  | >>> import os
 | 
						
						
						
							|  |  | >>> os.chdir('C:\\MPEI\\PO_ASY\\BerezhkovGit\\python-labs\\TEMA1')
 | 
						
						
						
							|  |  | ```
 | 
						
						
						
							|  |  | ## Файл Pr0.py
 | 
						
						
						
							|  |  | Содержимое файла:
 | 
						
						
						
							|  |  | ```py

 |

 | 
						
						
						
							|  |  |     trailing newline before reading input.
 | 
						
						
						
							|  |  | 
 | 
						
						
						
							|  |  |     If the user hits EOF (*nix: Ctrl-D, Windows: Ctrl-Z+Return), raise EOFError.
 | 
						
						
						
							|  |  |     On *nix systems, readline is used if available.
