PYTHON Suppose you need to import a single class named GeneTools from a module named bioinformatics, in Python. Which of the following represents the correct use of an import statement?

		import GeneTools from bioinformatics
		from bioinformatics import GeneTools
		from bioinformatics import *
		import GeneTools

Expert Solution

Ans: from bioinformatics import GeneTool

Explanation:

import is used to import modules in python.
The modules contain pre-defined classes,functions,types etc,.
To import only a required class or function etc., from a module:
- from module_name import required
Here in this example, the module is bioinformatics and the only class that needs to be imported is GeneTools.
- So, from bioinformatics import GeneTool should be used.

While other options are:

import GeneTools from bioinformatics: bioinformatics is the module that contains GeneTools, but not the other way around.

So, this option is incorrect.

from bioinformatics import * - This will import all the functions and classes from the module bioinformatics not just a single class. So, this option is incorrect, since only a single class needs to be imported.

import GeneTools - This option is incorrect as there is no module named GeneTools.

Programming language is in python 3 For this project, you will import the json module. Write a class named NobelData that reads a JSON file containing data on Nobel Prizes and allows the user to search that data. It just needs to read a local JSON file - it doesn't need to access the internet. Specifically, your class should have an init method that reads the file, and it should have a method named search_nobel that takes as parameters a...

The first random number generator comes from Python itself. To use it you need to import the Python package. Then call the random() method. See below. import random print (random.random()) It is important to know that a random number generator really is random. If so, it should have uniform distribution between 0 and 1. Test the random number generators in Python for uniformity.

Copy class CirclesViewer from Codecheck and complete it. You need to import the graphics package. After completed, the program will ask the user to enter an integer between 1 and 10 then draw the specified number of circles. The radius starts at 10 and increments by 10 for each next one. They all touch the line x = 5 at the left and the line y = 10 at the top. Another way to look at this is that the...
