Here, we will create the sample NumPy array that we will turn into a list in this tutorial. Therefore, run the line of code below to create the array.my_array = np.array([1, 2, 3, 4, 5])The created NumPy array, my_array, contains 5 integers. Now, let’s convert it to a ...
n=np.log(4*10**6*np.sqrt(5)+0.5)/np.log(phi)print(n)#3\.Create an arrayof1-n n=np.arange(1,n)print(n)#4\.Compute Fibonacci numbers fib=(phi**n-(-1/phi)**n)/np.sqrt(5)print("First 9 Fibonacci Numbers",fib[:9])#5\.Convert to integers # optional fib=fib.astype(int...

Check your Python script to make sure that you are using the correct attribute name for numpy. For instance, if you are trying to use the “int” attribute of numpy to convert an array to integers, use “numpy.astype(int)” instead. 3. Restart the Python interpreter In some cases, rest...

The uniform distribution of integers is convenient for this example, but you can also use other distributions.The head of computing analyzed the results of each class separately and now wants to convert the array into a single row containing all the results to continue working on the year as ...
