In one statement, it is allowed to initialize several variables with the same value. This can be done using the assignment operator =. For example, to initialize variables a, b and c and assign them the value 8, we use the notation: a = b = c = 8
On the contrary, several variables can be initialized with different values and written all in one statement, using a comma as a separator. For example, as an initialization of variables a, b and c with numeric values 1, 2, 3 we use the notation: a, b, c = 1, 2, 3
Some programming languages, such as Java, require variable types to be specified when declaring them. In this case, a certain amount of memory is reserved. This technique is known as static typing. This restriction is not imposed on variables in Python, and memory is allocated in accordance with the values assigned to the variables (dynamic typing). This means that a variable can contain both integers and floating point numbers, text strings, or boolean values. You can add comments to your Python programs to describe instructions or sections of code. The # symbol is used for this. Anything after this character to the end of the line is ignored by the Python interpreter. Comments are very useful – they help make your code understandable for others, as well as for yourself when you come back to it later.
