using append in python

List = ["One", "value"]

List.append("to add") # "to add" can also be an int, a foat or whatever"

#List is now ["One", "value","to add"]

#Or

List2 = ["One", "value"]
# "to add" can be any type but IT MUST be in a list
List2 += ["to add"] # can be seen as List2 = List2 + ["to add"]

#List2 is now ["One", "value", "to add"]

list.append(item)

it=[]
for i in range(10):
  it.append(i)

list1 = ["hello"]
list1 = list1 + ["world"]

 list = ['a', 'b', 'c', 'd']
  print list[1:-1]   ## ['b', 'c']
  list[0:2] = 'z'    ## replace ['a', 'b'] with ['z']
  print list         ## ['z', 'c', 'd']

append()

lst=[1,2,3,4]
print(lst)

#prints [1,2,3,4]

lst.append(5)
print(lst)

#prints [1,2,3,4,5]
