Python Learning Note (ii) Two ways of implementing the first Python program

In interactive mode:

If you want Python to print out the specified text, you can use a print statement, and then enclose the text you want to print in single or double quotes, but you can't mix single and double quotation marks:

>>> print ' Hello,world '
Hello,world
In interactive mode, although convenient, but the execution of the code can not be saved, next we use a text editor to write and can be saved.

Open notepad++, choose the code you've edited, Python

# hello.py
print ' Hello World '

The last file name is hello.py, open the command line CD to the file's save path and enter the Python hello.py.

The result is:

Python hello.py
Hello World
Note:

1. #是python的注释部分类似c语言的//, the text python after it is not executed.

2. If the output kanji, must be converted to Unicode encoding, the format of print U ' Hello '

3. Check if your path is correct when you are prompted to do not have a file
