Python “hello, world!” (in a file)¶
This tutorial recaps the Python “hello, world!” of the previous the tutorial. The difference is that here you’ll save the code you write to disk.
Writing the file¶
Change to whatever directory you’d like and then use your text editor to create
a new file called
Type the following line of Python code into
hello_world.py when you’re done.
Interpreting the file¶
Open the terminal and call Python on
$ python hello_world.py hello, world!
hello_world.py as input and outputs
hello, world! to the
Repeating the process¶
Working with Python files means doing these things:
1. write a file 2. interpret the file 3. repeat 1 - 2
Experience will make this edit-interpret loop familiar. And no matter how complicated the projects you develop this way of working with Python files will stay the same.
