- 2. • As we know that in order to communicate with a computer system, we need a language. This language may be C, C++, Java, Pythonor any other computer language. Here we will discuss PYTHON. • Python was developed by Guido Van Rossum in 1991 when he was working with National Research Institute of Mathematics and Science in Netherland. • Python was named from a comedy series “Monty Python’s Flying Circus” telecasted on BBC. • Python can be used as OOL and POL. Python (a ComputerLanguage)
- 3. Python (a ComputerLanguage) • Actually, Python is inspired by two languages - 1. ABC language which was an optional language of BASIC language. 2. Modula-3 • Python is very easy learning language as most of its syntax seems to be like in English. • It is possible to get desired output in minimum instructions. • It’s an Interpreted language. • It’s a complete language in itself and it is very easy to download and install. • It is a platform independent and portable language. • It is Free Open Source.
- 4. Python (a ComputerLanguage) • It is possible to develop various Apps with Python like– • GUI Apps • Web Apps • Games • DBMS Apps • Scripting etc.
- 5. Python (a ComputerLanguage) Limitations- There are few limitations in Python which can be neglected because of its vast usage. • It is not a Fast Language. • Libraries are very less. • It is week in Type binding. • It is not easy to convert in some other language.
- 6. Python (a ComputerLanguage) HOW TO INSTALL? •Python can be downloaded from www.python.org. •It is available in two versions- • Python 2.x • Python 3.x •We will download 3.6.5 here. •Open www.python.org on any browser.
- 7. Python (a ComputerLanguage) HOWTOINSTALL? • SCROLL DOWN.
- 8. Python (a ComputerLanguage) HOWTOINSTALL? Click on Downloads.
- 9. Python (a ComputerLanguage) HOWTOINSTALL? Click on Python3.6.5.
- 10. Python (a ComputerLanguage) HOWTOINSTALL? Download installer as per your Operating System (32 bit or 64 bit).
- 11. Python (a ComputerLanguage) HOW TOINSTALL? • Now run the downloaded setup, it will look like- Don’t forget to check this • Click on Install now.
- 12. Python (a ComputerLanguage) HOW TOINSTALL? • You can install python in this manner. • After installation, we will open Python IDLE 3.6.5. IDLE Python 3.6.5
- 13. Python (a ComputerLanguage) HOW TOINSTALL? • On opening Python IDLE 3.6.5, a window will be opened which will look like-
- 14. Python (a ComputerLanguage) HOW TO WORK? • We can work in Python in two ways- •Interactive Mode •Script Mode • Both have their own style of working. • Interactive mode works like a Command Interpreter as Shell Prompt works in DOS Prompt or Linux.. • ( >>>) we can execute any instruction of Python with this. • We can run a complete program by writing in Script mode.
- 16. Python (a ComputerLanguage) Scriptmode Click here to open a New File.
- 17. Python (a ComputerLanguage) Scriptmode • This is a script window. We can write a complete program here. • Afterwards, we save the file as we have saved the file with the name MyFirstProgram.py here. • Then in run menu, click on run module or use F5 Key.
- 18. Python (a ComputerLanguage) Scriptmode • As we click on run module or use F5, we switch to interactive mode where we get output of the program.
