    NumPy stands for numeric Python is a library used for working with arrays. In Python list only stores 1-D array while numpy can store n-dimensional arrays therefore it is very efficient. It only deals with numeric data type. import numpy as np ar=np.array([[25,26,27],[12,13,14]]) print(ar) output:-Read more

    import numpy as np

    ar=np.array([[25,26,27],[12,13,14]])

    print(ar)

    output:-

    [[25,26,27]

    [12,13,14]]

    What is the difference between the == and === operators in JavaScript?

    tezznew

    These are equality operators which are used for comparison. The difference is :- == :- It does the type conversion of the operands before comparison , basically change the data type of one of the two operands if both are not same. For ex:- let x=100 let y='100' console.log(x==y); output:- true It'sRead more

    These are equality operators which are used for comparison. The difference is :-

    == :- It does the type conversion of the operands before comparison , basically change the data type of one of the two operands if both are not same.

    For ex:-

    let x=100

    let y=’100′

    console.log(x==y);

    output:- true

    It’s true because it has changed the data type of y .

    === :- It doesn’t do the type conversion of the operands before comparison, basically do not change the data type of the operands.

    Example:-

    let x=100

    let y=’100′

    console.log(x===y);

    output:- false

    it’s false because it has not changed datatype of y.
