append a list inside a list python code example

Example 1: python how to append to a list

# Basic syntax:
your_list.append('element_to_append')

# Example usage:
your_list = ['a', 'b']
your_list.append('c')
print(your_list)
--> ['a', 'b', 'c']

# Note, .append() changes the list directly and doesn’t require an 
#	assignment operation. In fact, the following would produce an error:
your_list = your_list.append('c')

Example 2: add all items in list to another list python

a = [1]
b = [2,3]
a.extend(b)
print(a)

------  OR  -------
a += b

Example 3: python how to add one list to another list

# Basic syntax:
first_list.append(second_list) # Append adds the 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]

Example 4: python append to list

stuff = ["apple", "banana"]
stuff.append("carrot")
# Print to see if it worked
print(stuff)
# You can do it with a variable too
whatever = "pineapple"
stuff.append(whatever)
# Print it again
print(stuff)
