One such data type is the Python string, which is, uncoincidentally, the topic of the next article in the tutorial! The function shows the message to the screen.
The next line assigns the string to the variable and print its value to the screen.
The variable can hold various values at different times. Here are some examples:
Code language:Python(python)First, we created a variable with the value 4.
If we were calculating the total price of a shopping cart here, for example, a good name would be .
Don’t skimp on the number of characters in your variable names. But there are others too, like booleans and tuples.
Python has a built-in function called , which we can use to determine a variable or expression type. If you don’t, you’ll get an error.
The following are the variable rules that you should keep in mind:
- Variable names can contain only letters, numbers, and underscores ().
It holds the string . And when asked, Python indeed tells us that it is of class str, short for string. The maximum score is 100%. Head over to the next section to learn all about Python strings.

We can use camel-case in Python, but we prefer underscores for variable names, while camel-case is the norm for class names. But what about text? That’s why I wanted to show you one. Eventually, you’ll need to write code on your own, and running into errors is, unfortunately, a big part of the job. Follow the link for a more thorough explanation of integers if you like.
Variable type
A value assigned to a variable does not have to be a number, by the way. But before we do so, we’ll try and see if Python already knows what is:
Code language:Python(python)This is the way Python lets you know about errors. It’s better to have clean, readable names like instead of an abbreviation like .
For this, we use the Python variable. Python errors tend to be very helpful if you know where to look. Assignments are done with the ‘=’ character, which is conveniently called ‘is’. Good luck!
