There are dodgy differences in the way Python and C deal with variables. So it's worth to go on reading this chapter on data types and variables in Python. You know a lot, that's right, but not enough for Python. You could also make an int variable just by utilize the int() variable when you are assigning a variable from the beginning.Have you programmed low-level languages like C, C++ or other similar programming languages? If so, you might think you know already enough about data types and variables. This is because the int() function trims the numbers after the decimal, returning the integer number. In order to convert this number into an integer number, you use the float() function in Python.īe wary though that whenever you convert a float number to an integer variable in Python, your float number will round down to the nearest integer. Such numbers are useful to represent precise and exact values through decimals, such as 7.99. This can be useful when you want to convert a float variable into an integer variable.Ī float number is used whenever you need to represent real numbers, such as any number that is on the continuous number line (π, 7.5, √2. In order to manually state int variables in python, we can utilize the int() method. For instance, you can't have 4.5 cars, so you would make the variable that is representing cars an integer. If you ever need to double check the type of a variable, utilizing the type() function is very useful.įurthermore, integer variables are always useful often when dealing with real world objects. So what would happen if we divide two integer variables? Let's say for instance, 5 and 2.įirst, we would assign the two variables, in this case "number_one" and "number_two" can be assigned 5 and 2, respectively, and then we can use Python's built in division operator in order to divide the two numbers.įrom this, we can see that when you divide two integers and the quotient is not a whole number, Python automatically sets the result variable as a float variable, which can be shown by: type(result) Using our last example of the "hello_" variable, if we type the following line: type(hello_) If you're curious as to how we can check if the variable is actually an integer variable, you can also use the "type()" function in order to confirm the type of variable you have. In the example, we can see that the variable "hello_" was assigned 3, and therefore become an integer variable.

Using the variable naming rules stated before, an example of an integer variable in Python can be: hello_ = 3 ) are included in integer variables, including negative numbers (0, -1, -2, -3, -4, -5. As such, all whole numbers (0, 1, 2, 3, 4, 5. Integer variables, or "int" variables, are variables that specifically store, as the name suggests, integers as its value. So, now that we know the basic idea of variables, why are integer variables different from the others? 2.

  • Variable names cannot be a Python keyword.
  • Can have numbers included in the name but not at the beginning.
  • Variable name has to start with a letter or underscore.
  • No special characters allowed other than underscore.
  • To name variables in Python, there are several rules, including: It basically stores data in the program for the computer to utilize whenever it needs to access that data again. What exactly are variables, and why should we care about int variables? We'll go over such topics in this article and more.įirst, variables in programming can be defined as reserved memory locations - or points - that store information in a program.
  • How can we manually create int variables?.
