1.The first python source file

2.The points need to be noticed

3.Example running results

4.The second example

5.The basic format of python program

        Firstly, we need to enter the IDLE, then choose file - new file;

        Then a new .py file has been created as no name. Then it needs to be saved with a customized name.
        Below is my example for training.

Figure1: my first python source file 

There are fews points need to be noticed:

1. Do not use the blank casually. Because in python syntax, blank indicates indent , 缩进的意思

2.Do not use the chinese charactor like brackets - ( , quotations - , commas- , .

 Figure2: my first python source file running results

Figure3: my second python source file running results

        (1). The blank in front of one row, and one Tab(4blanks), intend to decide the level of indentation in a logical way, so it could divide the group of your program.

        (2). The sentence starts from this first character of one row.

Ok, this is the end of our today s lesson learn, please stay tuned on the next episode.
