Example 2: how to remove an element in a list by index python

list = [0, 1, 2, 3, 4, 5]

print(list)
# [0, 1, 2, 3, 4, 5]

del list[0]
print(list)
# [1, 2, 3, 4, 5]
      
del list[-2]
print(list)
# [1, 2, 3, 5]
      
del list[0:2]

# removes item with given name in list
list = [15, 79, 709, "Back to your IDE"]

list.pop(0)

# ...and returns also the "popped" item
item = list.pop()

#Let's say that we have a list of names.

#And to delete, I do this:
listnames.remove(remove)
