This article mainly introduces "what are the characteristics of python ndarray array objects". In daily operation, I believe many people have doubts about the characteristics of python ndarray array objects. The editor consulted all kinds of data and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts about "what are the characteristics of python ndarray array objects?" Next, please follow the editor to study!

1. The numpy array is a homogeneous array, that is, all elements must have the same data type.

2. The ndarray array generally requires that all elements have the same data type, with the subscript starting from 0, and the subscript of the last element is the array length minus 1.

Example

Import numpy as np a = np.arange (0,5,1) print (a) b = np.arange (0,10,2) print (b) what is Python mainly used to do Python is mainly used in:

1. Web development

2. Data science research

3. Web crawler

4. Embedded application development

5. Game development

6. Desktop application development.

At this point, the study on "what are the characteristics of python ndarray array objects" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
