you can import the Numpy module and create a list calledmylist. Then, you can use thenp.array()method to convert the list into a NumPy array and assign it to the variable arr. Finally, you can print the resulting NumPy array.

However, its close coupling with the Python text model, especially the type restricted convenience methods on the builtin str, bytes and bytearray types, has historically obscured that fact. As a key step in clarifying the situation, the codecs.encode() and codecs.decode() convenience ...
array = np.arange(1,20) print(array) array.tofile('hello.csv', sep = ',') Output: In this example, I have imported a module callednumpy as npand created a variable called anarray, and assignedarray = np.arange(1,20). Thenp.arangeis used to create an array with the range, (1...
