print( in this examplewe ask python to remember the value six and use the label so we can retrieve the value later we verify that python has actually remembered the value using print then we ask python to retrieve and multiply it by seven and put the newly computed value in then we ask python to print out the value currently in even though we are typing these commands into python one line at timepython is treating them as an ordered sequence of statements with later statements able to retrieve data created in earlier statements we are writing our first simple paragraph with four sentences in logical and meaningful order it is the nature of an interpreter to be able to have an interactive conversation as shown above compiler needs to be handed the entire program in fileand then it runs process to translate the high-level source code into machine language and then the compiler puts the resulting machine language into file for later execution if you have windows systemoften these executable machine language programs have suffix of exeor dllwhich stand for "executableand "dynamic link libraryrespectively in linux and macintoshthere is no suffix that uniquely marks file as executable if you were to open an executable file in text editorit would look completely crazy and be unreadable^?elf^ ^ ^ ^@^@^@^@^@^@^@^@^@^ ^@^ ^@^ ^@^@^@\xa \ ^ ^ ^@^@^@\ ^]^@^@^@^@^@^@ ^^@^ ^@(^@$^@!^@^ ^^@^@ ^@^@^@ \ ^ ^ \ ^ ^ \xe ^@^@^@\xe ^@^@^@^ ^@^@^@^ ^@^@^@^ ^@^@^@^ ^ ^@^@^ \ ^ ^ ^ \ ^ ^ ^ ^@^@^@^ ^@^@^@^ ^@^@^@^ ^@^@^@^ \^ ^hqvht\ ^ ^ \xe it is not easy to read or write machine languageso it is nice that we have interpreters and compilers that allow us to write in high-level languages like python or now at this point in our discussion of compilers and interpretersyou should be wondering bit about the python interpreter itself what language is it written inis it written in compiled languagewhen we type "python"what exactly is happeningthe python interpreter is written in high-level language called "cyou can look at the actual source code for the python interpreter by going to www python org and working your way to their source code so python is program itself and it is compiled into machine code when you installed python on your computer (or the vendor installed it)you copied machine-code copy of the translated python program onto your system in windowsthe executable machine code for python itself is likely in file with name likec:\python \python exe
