Here, we have a 2-D matrix of tuples and we need to convert this matrix to a 1D tuple list.
Python code to convert a NumPy matrix to list # Import numpyimportnumpyasnp# Creating a numpy matrixmat=np.matrix([1,2,3])# Display original matrixprint("Original matrix:\n",mat,"\n")# Converting matrix into a listres=mat.tolist()# Display resultprint("Result:\n",res) ...

In the example above, we use a nested list comprehension to iterate over each element of the originalmatrixand construct a new matrix in which the rows and columns have been swapped. The outer loop iterates over the columns of the original matrix, while the inner loop iterates over the row...
Once you have NumPy installed, you can easily convert lists to arrays using the methods outlined below. Method 1: Using the np.array() Function The simplest and most straightforward way to convert a list to a NumPy array is by using thenp.array()function. This function takes a list (or...
