append array python code example

Example 1: append element to an array python

Example 2: append item to array python

data = []
data.append("Item")

Example 3: append 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"]

Example 4: python add element to array

my_list = []

my_list.append(12)

Example 5: 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 6: append value to numpy array

x = np.random.randint(2, size=10)
x = np.append(x, 2)
