Return a new array setting values to zero. 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. One thing to be wary about when using [(0,0,0)]*L ; this achieves its … See also. zeros. 6 Ways to check if all values in Numpy Array are zero (in both 1D & 2D arrays) - Python; Python: Find index of element in List (First, last or all occurrences) ... 2019 at 5:47 pm none Comment author #25361 on Python : How to create a list and initialize with same values by Create a list of random integers.
