This article will explain in detail how to improve code efficiency skills in Python, and the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Objects are equal. What do you think is the difference between type (a) = type (b) and type (a) is type (b)? Why did you choose the latter? What does the function isinstance () have to do with this?

In example 4.1, we provide a script to demonstrate the use of the isinstance () and type () functions in a run-time environment. Then we discuss the use of type () and how to port this example to isinstance (). Run typechk.py and we get the following output:

-69 is a number of type: int 99999999999999999999 is a number of type: long 98.6is a number of type: float (- 5.2mm 1.9j) is a number of type: complex xxx is not a number at all!

Example 4.1 the typechk.py (typechk.py) function displayNumType () takes a numeric parameter, and in the Python technique, the built-in function type () is used to confirm the numeric type (or not a numeric type).

#! / usr/bin/env python def displayNumType (num): print num, 'is', if isinstance (num, (int, long, float, complex)): print' a number of type:', type (num). _ _ name__ else: print 'not a number at allrooms DisplayNumType (- 69) displayNumType (999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999L) displayNumType (- 5.2q1.9j) displayNumType ('xxx') on how to improve code efficiency skills in Python is shared here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
