Variables and expressions

- [Instructor] Now let's take a look at how the…Python language works with variables.…So in your editor open the file named…variables_start.py.…So first note that comments in Python…are declared using the hash character.…Let's go ahead and declare a variable,…so I'll write F equals zero…and let's print it, all right, print F.…So in this case I'm declaring a variable named F…and assigning it the value of zero…and next I call the print function,…which is going to print the value of that variable.…

So let's go ahead and save and run this program…and remember if you're not using VS code…you can just run this in your terminal.…So I'll just go ahead the debug view and run this,…show the output window,…and you can see that it's printing the value zero,…because that's what the value of F is.…All right, so let's add a few more lines of code.…So I'll write F equals ABC…and then once again we'll print F.…Now I'm saying that whatever the value of F was before,…it was an integer before now let's make it a string.…

Let's go ahead and save and run again…
