Using constants in the CODATA database

In the next recipe, we will cover the constants like those used in the CODATA database.

Getting ready

The following the functions needed to be installed before we use them.

Constants database

In addition to the preceding variables of the function, scipy.constants also contains the 2014 CODATA recommended values database containing more physical constants.

In the following table we can see the name of the functions and the description

Function	Description
value (key)	Value in physical_constants indexed by key
unit (key)	Unit in physical_constants indexed by key
precision (key)	Relative precision in physical_constants indexed by key
find ([sub, disp])	Return list of physical_constant keys containing a given string
ConstantWarning	Accessing a constant no longer in the current CODATA dataset

How to do it...

The following functions represents and execute the following commands:

1. Install the proper function
2. Execute the function
3. Solve the function
4. The result will be presented
