How do I find the shape of a NumPy array?
You can find the shape of a NumPy array using the .shape
attribute. For example, array.shape
will return the dimensions.
Can you show me an example?
Sure! If you have an array like import numpy as np; arr = np.array([[1, 2, 3], [4, 5, 6]])
, then arr.shape
will return (2, 3)
.
What does the output (2, 3)
mean?
It means the array has 2 rows and 3 columns.
Is there a way to change the shape of an array?
Yes, you can use the .reshape()
method to change the shape of an array, as long as the total number of elements remains the same.
