When I am reshaping the array ar as :ar.reshape(4,2) ,I am getting an array of 4 rows and 2 columns .However, when I am finding shape of ar using: ar.shape , output is coming (2,4). Why is (4,2) not shown even after reshaping the array?
In [11]: arOut[11]: array([1, 2, 3, 4, 5, 6, 7, 8])In [12]: ar.shape(2,4)---------------------------------------------------------------------------TypeError Traceback (most recent call last)<ipython-input-12-ac49df2b586f> in <module>----> 1 ar.shape(2,4)TypeError: 'tuple' object is not callable
It is said that shape is a method.But as far as my knowledge goes, it is an attribute of ndarray.Plz look into it.
--------------------------------------------------------In [68]: print(ar)[1 2 3 4 5 6 7 8]In [69]: ar.shape()---------------------------------------------------------------------------TypeError Traceback (most recent call last)<ipython-input-69-895c9f3eff17> in <module>----> 1 ar.shape()TypeError: 'tuple' object is not callable
Mam why do we have to use 2 brackets in the zeros method for giving only 1 set of values to it? I have tried it with one braces(opening and closing) then it is giving error. My OS used : Windows 10 ==>TypeError Traceback (most recent call last)<ipython-input-3-4b18b0e09899> in <module>----> 1 b=np.zeros(2,2)TypeError: data type not understood
Regrding the Arrays... While importing the numpy as np command did not execute. What could be the possible reasons for the same ?
Dear Sir/Madam,Such like of numpy library, how many library should we use for general programming?
Sir/madam,What is exactly the use of zero method? it let us create arrays only with zero elements? Where we use such arrays?
Sir/Madam,I am not clear with the explanation given in video about dtype? Is it come only in output just as a message or can do we also use in any input commands also?
