When “configuring the Python Interpreter,” as you had to do when you first set up PyCharm, you were telling PyCharm what version of Python to use behind-the-scenes (i.e. saying p ython3 vs. p ython2 when running scripts and using python3 when executing commands in the Python Interpreter/Console).

wrapped function should just be called without caching. Note: To use args and kwargs as dictionary keys, they must be hashable, which basically means that they must be immutable. args is already a tuple, which is fine, but kwargs have to be converted.

Up until now, to pass arguments to a function from the command line, we've relied on the input() function. We'll look at a couple different ways of passing arguments from the command line starting with sys.argv. sys.argv is a list that contains the arguments passed to Python via the command line. Copy the following code into a file:

This usage - declaring a function like def general_function(*args, **kwargs) - is the most general way to define a function in Python. A function so declared can be called in any way, with any valid combination of keyword and non-keyword arguments - including no arguments. Similarly, you can call a function using both - and both will be unpacked:

*args and **kwargs are mostly used in function definitions. *args and **kwargs allow you to pass an unspecified number of arguments to a function, so when writing the function definition, you do not need to know how many arguments will be passed to your function. *args is used to send a non-keyworded variable length argument list to the ...

Once a fitting model is set up, one can change the fitting algorithm used to find the optimal solution without changing the objective function.
