To save space, Python displays numbers as 1. instead of 1.0 when there’s nothing interesting after the decimal point. Our call to numpy.loadtxt read our file, but didn’t save the data in memory. To do that, we need to assign the array to a variable. Variables. A variable is just a name for a value, such as x, current_temperature, or subject_id.

Python has support for all the regular numeric data types, including integers, floating-point decimals, and even complex numbers. There are plain integers, (in the range -2147483648 through 2147483647), long integers (in unlimited range, subject only to available memory), and Booleans, which can only be 0 (False) or 1 (True).

It is best to think of the equal sign as “gets”. That is, think of the first example as “the variable a gets the floating point value 2.3” and the second as “the variable name gets the string Joe”. An assignment command such as these literally reserves space in the computer’s memory for the variable and tags it with the variable name.

The equal sign in Python (and most programming languages) is different than the equal sign in math. In Python, the equal sign is the assignment statement. It tells the computer to figure out the value of the right hand side at that snapshot in time and it changes the value of the variable on the left of the equal sign to that value.

Students must understand that variables in programming are not the same as variables in other mathematics courses. A variable is traditionally defined in mathematics courses as a symbol that represents an unknown value. In programming, a variable is a name given to a location in memory. It makes sense to write x + 1 x.

We are very familiar with the idea of a variable. In many programming languages, there is a clear distinction between 'variables' and their more complex cousins, 'objects'. However, in Python, everything – even the most "simple" variable, is still considered to be an object. Therefore, you will frequently hear the terms used interchangably.

Variables can hold a few different types of data: numbers, Boolean values (i.e. true and false), text characters, or strings of characters to make a word or phrase. Different data types will require the variable holding it to use different amounts of memory, and they operate differently from each other.

Python uses dynamic scoping: a variable is added by executing an assignment to it. ... Dry running a program to show the sequence of values of each variable makes this clear. Step. numA. numB. Code. 1. 5. numA = ... 2. 15. numB = ... 3. 5. numB = numA. 4. 5. numA = numB. M. ... So an assignment updates a variable, which is a location in memory ...
