May 31, 2024 · Below are the possible approaches to using a variable from another function in Python. Using Global Variables; Using Function Parameters; Using Class Attributes; Use a Variable from Another Function Using Global Variables. In this example, we are using global variables to share a variable between functions. First, we declare the variable as ...
Notice that to read global variables inside a function, you do not need to use the global keyword. However, to write to a global variable within a function, you do have to use the global keyword in front of the variable declaration within the function, or else the function will consider it a separate, local variable, and not update the global variable when you write to it.

There are multiple ways that enable you to use a variable from anotherfunction in Python: 1. You can return the variable from the first function and store the returnvalue in the second function. 2. The second function can take the variable as a parameter. 3. You could define the functions as class methods and access the variable onthe selfobject. 4...
Alternatively, you can pass the variable as an argument to the second function. The first function returns a list of numbers using the returnstatement. The second function takes a list as a parameter and prints it. When calling the second function, we passed it the result of calling the firstfunction. The second function gets called with the list t...
Alternatively, you can wrap the functions in a class. The Employee() class takes 2 parameters upon instantiation - first andlast. The increase_salary and decrease_salarymethods don't take any parametersand can be called on a class instance. The methods increase or decrease the salaryinstance variable. You can optionally set a default value for the ...
You can also mark a variable as global to be able to use it in another function. We initialized the variable in the global scope, setting it to an empty string. The globalkeyword enables us to update the value of the variable from theouter scope from within a function. Once the variable's value has been updated, we can access the updated value inth...
You can also use a variable from another function by setting functionattributes. We used dot notation to set the website attribute in function_a. You can access the attribute directly on the function object, e.g.function_name.attribute_name. We are also able to access the attribute from other functions. However, note that function_ahas to be invoke...

Aug 19, 2023 · You can also pass the variable as a parameter to a function to use the same variable in different functions. Here is an example: # Define two functions def function1 ...
Dec 16, 2022 · This is how we will approach the current task of accessing a variable from outside the function. This is done similar to how we access members of a class by their object using the “.” operator. How to use a variable from another function in Python: The variable can be assigned to the function object inside the function body.
