In Python, dictionary data types are used to store data collection in key-value syntax. Every key in the dictionary has a unique value that can be accessed in a program using the specified key name. Python offers various methods to apply some operations on the keys of a dictionary. ...
When working with numpy, avoid explicit for-loops over indices/axes at costs. For-loops will dramatically slow down your code. We can time code uising the %%timeit magic. Let's compare using explicit for-loop vs. using numpy operations. python %%timeit x = np.random.ran(1000, 1000) for...
