How to call a variable in a function python
One approach would be to make Show
Another approach is making
And finally, you could define both of your functions in a class, and make
Once you make a class, you have to instantiate an instance and access the member functions:

In Python, we can assign a function to a variable. And using that variable we can call the function as many as times we want. Thereby, increasing code reusability. Implementation Simply assign a function to the desired variable but without () i.e. just with the name of the function. If the variable is assigned with function along with the brackets (), None will be returned. Syntax: def func(): { .. } var=func var() var() Example: Python3
Output: GFG The following programs will help you understand better: Example 1: Python3
Output: 123 98 123 98 123 Example 2: parameterized function Python3
Output: odd number even number odd number Example 3: Python3
Output: 240 400 4000 How do you call a variable inside a function in Python?Use of “global†keyword to modify global variable inside a function. If your function has a local variable with same name as global variable and you want to modify the global variable inside function then use 'global' keyword before the variable name at start of function i.e.
Can you assign a function call to a variable in Python?In Python, we can assign a function to a variable. And using that variable we can call the function as many as times we want. Thereby, increasing code reusability. Simply assign a function to the desired variable but without () i.e. just with the name of the function.
How do you use a variable from another function in Python?The variable can be assigned to the function object inside the function body. So the variable exists only after the function has been called. Once the function has been called, the variable will be associated with the function object.
How do you access variables in Python?The variables that are defined inside the methods can be accessed within that method only by simply using the variable name. Example – var_name. If you want to use that variable outside the method or class, you have to declared that variable as a global.
