# Basic syntax:
first_list.append(second_list) # Append adds the second_list as an
# element to the first_list
first_list.extend(second_list) # Extend combines the elements of the
# first_list and the second_list
# Note, both append and extend modify the first_list in place
# Example usage for append:
first_list = [1, 2, 3, 4, 5]
second_list = [6, 7, 8, 9]
first_list.append(second_list)
print(first_list)
--> [1, 2, 3, 4, 5, [6, 7, 8, 9]]
# Example usage for extend:
first_list = [1, 2, 3, 4, 5]
second_list = [6, 7, 8, 9]
first_list.extend(second_list)
print(first_list)
--> [1, 2, 3, 4, 5, 6, 7, 8, 9]
list_1 = ['w','h']
list_1.append('y') # you need no veribal to store list_1.append('y')
print(list_1) # ['w','h','y']
list_2 = ['a','r','e']
list_1.append(list_2) # This also donot need a veribal to store it
print(list_1) # ['w','h','y',['a','r','e']]
list_1.extend(list_2)
print(list_1) # ['w','h','y',['a','r','e'],'a','r','e']
# please like
# Add to List
my_list * 2 # [1, 2, '3', True, 1, 2, '3', True]
my_list + [100] # [1, 2, '3', True, 100] --> doesn't mutate original list, creates new one
my_list.append(100) # None --> Mutates original list to [1, 2, '3', True, 100] # Or: <list> += [<el>]
my_list.extend([100, 200]) # None --> Mutates original list to [1, 2, '3', True, 100, 200]
my_list.insert(2, '!!!') # None --> [1, 2, '!!!', '3', True] - Inserts item at index and moves the rest to the right.
' '.join(['Hello','There'])# 'Hello There' --> Joins elements using string as separator.
#.append() is a function that allows you to add values to a list
sampleList.append("Bob")
print ("Bob should appear in the list:", sampleList)
#The output will be:
Bob should appear in the list: ['Bob']
How to append element to a list in Python
# Programming list
programming_list = ['C','C#','Python','Java','JavaScript']
# append the HTML item to the list
programming_list.append('HTML')
print('The new list is :', programming_list)
list1 = [10, 20, 4, 45, 99]
mx=max(list1[0],list1[1])
secondmax=min(list1[0],list1[1])
n =len(list1)
for i in range(2,n):
if list1[i]>mx:
secondmax=mx
mx=list1[i]
elif list1[i]>secondmax and
mx != list1[i]:
secondmax=list1[i]
print("Second highest number is : ",
str(secondmax))
Output:-
Second highest number is : 45
How to append a list into an existing list
# Programming list
programming_list = ['C','C#','Python','Java']
frontend_programming =['CSS','HTML','JavaScript']
# append the frontend_progamming list into the existing list
programming_list.append(frontend_programming)
# Note that entire list is appended as a single element
print('The new appended list is :', programming_list)
# Addition of elements in a List
# Creating a List
List = []
print("Initial blank List: ")
print(List)
# Addition of Elements
# in the List
List.append(7)
List.append(2)
List.append(4)
print("
List after Addition of Three elements: ")
print(List)
# Adding elements to the List
# using Iterator
for i in range(5, 10):
List.append(i)
print("
List after Addition of elements from 5-10: ")
print(List)
# Adding Tuples to the List
List.append((5, 6))
print("
List after Addition of a Tuple: ")
print(List)
# Addition of List to a List
List2 = ['softhunt', '.net']
List.append(List2)
print("
List after Addition of a List: ")
print(List)
list_1 = ['w','h']
list_1.append('y') # you need no veribal to store list_1.append('y')
print(list_1) # ['w','h','y']
list_2 = ['a','r','e']
list_1.append(list_2) # This also donot need a veribal to store it
print(list_1) # ['w','h','y',['a','r','e']]
list_1.extend(list_2)
print(list_1) # ['w','h','y',['a','r','e'],'a','r','e']
