The NumPy function uses the round half to even strategy, just like Python’s built-in round() function. For example, the following code rounds all of the values in data to three decimal places: Python >>> np.round(data, decimals=3) array([[-0.69 , -2.105, -0.788, 0.934], [ ...
When working with user input, it’s common to require multiple values from the user. Python provides a convenient way to handle this using thesplit()method, which divides a string into a list of substrings based on a specified separator. In the case of user input, we can usesplit()to ...
