Python 3 x How do you find the length of a list inside a list
5 You have a typo you wrote l 0 where l would have sufficed for x in l print len x Note that it is bad practice to have side effects in a list comprehension list comprehensions are to create values not to change global state You should use a for loop
Find the dimensions of a multidimensional Python array, In Python is it possible to write a function that returns the dimensions of a multidimensional array given the assumption that the array s dimensions are not jagged For example the dimensions of 2 3 4 2 3 2 would be 3 2 while the dimensions of 3 2 4 5 3 4 2 3 would be 2 2 2
