Python-i filename

Originally this command is no longer pathon under the IDE, it is used in the console.

A =1
b =2
Print (' a+b=%d '% (a+b))

2. Log in to the console, enter the aa.py directory (must enter the file directory, or the system cannot find the file), enter Python-i aa.py. The interface will output the results.

3. Now that we have entered the Python edit mode, we can continue to execute the python command:

4. Enter exit () to exit the Python edit:
