NumPy Codes and import

-

 First open Anaconda, then launch the jupyter notebook.


Then create new python 3 file.


Here we will discuss NumPy arrays and codes.


Let's print an array.


Oh ! Was it easy ? Yes .It was.


Now we will import numpy and use that to assign the array to a variable, and some other things also will try ...





Here, I created an array . Then I imported NumPy as np . Then I used np to set the array to the variable arr.



2D array NumPy



There are 2 braces in the beginning so 2D array.3 rows 3 columns.



arrange is used to quickly generate an array in NumPy of certain condition or in normal as per above example.


link space

--------------:


here the third argument is considered as no of points as you want where as arrange take it as steps as you want.


identity matrix




randn() shows a standard normal distribution.


randn() in 2  Dimension



Printing random integer using randint()




max() for finding the highest number in the array and min() for the lowest number.

argmax() used to show the index of the max(highest) number from the array.



dtype() gives you the datatype.



If we don’t want to use numpy.random , we can declare it as an alias i.e. randint or enything elase.

 All Concepts sumerized .... ------------------------------------------------------------- *** Java is partially Object-oriented as it has primitive types. (Primitive i.e. int, float are not the objects, to convert them to use as Object, we use wrapper class) ***Java is platform-independent but JVM dependent. And JVM is platform dependent because for Linux there is a different JVM whereas for windows it's different. _-_____-----___--___--____--- Oo ps Conc ept  _-_____-----___--___--____--- abstraction ,  encapsulation ,  inheritance ,  polymorphism .  Inheritance : Real-World Example : Children have some of the qualities of their parents and grandparents or their ancestors. Java Example: There is a method in the parent class and you want the same method to create in a child class. Why create a new one if it already exists. As a child, you can inherit the method. There are a few variables in a class and you need them .So why to create new variables. We can ...

Java.Util.Function ------------------------ Java.Util.Function added in java 8. So let's have a closer look into it. To go through the documentation click the below link. https://docs.oracle.com/javase/8/docs/api/java/util/function/package-summary.html The 4 important topics are , 1. Predicate 2. Consumer   3. Function 4. Supplier A youtube example for better understanding is :  https://www.youtube.com/watch?v=Tapz6_T5oHY Consumer :  --  two methods, accept(T t) and andThen() ** accept(T t) , returns void means no thing returned. It accepts only input. **andThen executes two consumers one after another. #java #java8 #java 8 #java.util.function #javaFunction #java function #java consumer #java predicate #java supplier #java lambda expression
