Highlight

Visual Studio Code, the print() and input() function
Visual Studio Code downloading failed.
But I practiced some simple coding.

print('I am a hero')
I am a hero
print('I love dogs','I love cats')
I love dogs I love cats
print(8487-47566)
-39079
name=input()
JoJo
 name
'JoJo'
 print(name)
JoJo

Finally I installed the Visual Studio Code and made a .py file. WHAT A TOUGH WORK!

I am very unfamiliar with the Visual Studio Code. I have to use it everyday.
NOTE: 1.The text after a # is simply ignored as a human-readable comment and is not considered part of the statement’s syntax.
2.Using 4 spaces for indentation.( But how to set the tab to automatically convert to 4 spaces in my Visual Studio Code?)

Some reviews:

1. The Python interpreter is a program that runs the Python programs you write.
2. Source code is the statements you write for your program—it consists of text in
   text files that normally end with a .py extension.
3. Byte code is the lower-level form of your program after Python compiles it. Python automatically stores byte code in files with a .pyc extension.
4. The PVM is the Python Virtual Machine—the runtime engine of Python that interprets your compiled byte code.
5. Psyco, Shedskin, and frozen binaries are all variations on the execution model.
6. CPython is the standard implementation of the language. Jython and IronPython implement Python programs for use in Java and .NET environments, respectively;they are alternative compilers for Python.
