Python code typed on console for practice, other than this we can also save our code to various files.
Step 1:
In the following example we have created testfile.py(.py is python file extension) in python home directory which is the directory in which python is installed. See the following Image :
Step 2:
Now type the following code into your testfile.py which we made earlier :
def Hello(): print "hello function" return 20
Step 3:
Now open your console and type the following commands:
>>> import testfile >>> a = testfile.Hello() hello function >>> a 20 >>>
First of all we need to import the file we have created, import it without extension. Next I have called this function into a variable say a which will store the returned result. and at last the function displays hello function and value of 20 is displayed on screen.
