Hello, please, I would like to copy a certain list in python. The total size of the list is 150 and I want to remove the last 50 items from the list. Here I will represent a list 100 times smaller, that is to say with 15 elements and that I want to remove the last 5.
l = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
How could I do this in a loop? or while?
Thank you!
In fact to copy the last 5 they to another list:
l2 = l[-5:] # l2 = [11, 12, 13, 14, 15]
To remove the last 5:
del l[-5:] # l = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
In Python version 2.7 just do so
l2= l[:-5]
I found a solution, but I do not know if it's correct:
l = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
percent_l = 0.5
TAM = len(l)
taxa_c = int(percent_l * TAM)
print("taxa_c",taxa_c)
new_list = []
for i in l[0:taxa_c]:
new_list.append(i)
print("new_list", new_list)
In this case I am calculating for a fee, the last percentage I would like to remove.
