demand

Requirements describe ： Will a list on length n Divide equally

for example ：

1. Input list by ： list_data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
2. Average length n by ： num=3
3. Expected output ：[[1, 2, 3], [4, 5, 6], [7, 8, 9], [10]]

1. One line of code

[list_data[i*num:(i+1)*num] for i in range(int(len(list_data)/num) + 1) if list_data[i*num:(i+1)*num]]

2. Function implementation and the above

The code is as follows ：

# 2. One line function version
