Find length of 2D array Python
arrays, python
Solution
Like this:
numrows = len(input) # 3 rows in your example
numcols = len(input[0]) # 2 columns in your example
Assuming that all the sublists have the same length (that is, it's not a jagged array).
Problem
How do I find how many rows and columns are in a 2d array? For example, ``` Input = ([[1, 2], [3, 4], [5, 6]])` ``` should be displayed as 3 rows and 2 columns.
