Or even simpler, in Python 2.x you can do this to initialize a list with values from 0 to 9: lst = range(10) And in Python 3.x: lst = list(range(10)) The problem is that they're all the same exact list in memory. Important thing about a list is that items in a list need not be of the same type. First, create a complex vector. Just like the previous solution, we can use List Comprehension to iterate over each element in the numpy array and create a list of values which are non zero. That gives us the answer 1, which is then passed to the left side of the assignment. The elements are comma-separated and can be of different data types.

What is the difficulty level of this exercise? To get the list of zeros, we have to create a variable with the name “n” and then ”  * n “ will create a list with zeros in python. Return an array of ones with shape and type of input. Then by checking if the size of the list is 0 or not, we can confirm if all values are zero in our numpy array or not, zeros. In Python, we declare the 2D array (list) like a list of lists: cinema = [] ... Then we generate 5 more lists (columns) using a for loop, fill each list with 5 zeros using a nested loop and add the list to the original list as a new item. Return a new array of given shape and type, filled with zeros. 02, Sep 19. The obvious solution appears to be wrong: a = [ * m] * n This can be easily seen if you set the value of a to 5, and then print the value of a — it will also be equal to 5.
