Getting Started with Python

Lets Start

• Ask each student all the different language (1 each)

• Explain about the language type

• VSCode Installation (While downloading, ask about type of processor arch and OS )

• Browser user agent (vscode knowing from which OS the request is coming from )

• Installation on python (About different version about the python )

• Creating A directory

• Guiding file naming convention, for easy learning. Example (001_helloworld.py, 002_comment.py)

• A "Hello World" program.

---

001_helloworld.py

print("Hello World")

Few more example

print("Hello, 世界")
print("Emoji: 😊")

print("\u03C0")   # Greek letter pi: π
print("\U0001F600") # Smiling face emoji: 😀

print('\u0B05')
