Как создать массив в Python
array = ["1st", "2nd", "3rd"]
#prints: ['1st', '2nd', '3rd']
array.append("4th")
#prints: ['1st', '2nd', '3rd', '4th']

array = ["1st", "2nd", "3rd"]
#prints: ['1st', '2nd', '3rd']
array.append("4th")
#prints: ['1st', '2nd', '3rd', '4th']# In python, arrays are actually called lists. Same thing tho
list_or_array = [1.0, 2, '3', True, [1, 2, 3, 4]]
"""
So, list can contain floats, integers, strings, booleans, nested lists, and
practically any other datatype
"""#python arrays
#arrays can be defined in the following
# class array.array(typecode[, initializer])
# The typecode character used to create the array eg i for integers , c for strings etch
array = array('i', [1, 2, 3, 100, 4, 4, 5, 20, 20, 20])
#You can perform serveral methods eg remove(),pop()
#removing the last element in the array
array.pop()
#Adding elements to array using the append and insert method
array.append(20)
array.insert(4,100)#adds 100 at index 4
#I will make an array and the contents will be called "Hello", "Nice", "Cool"
#Array
#By the way, you can make whatever variable name you want.
#I will also print the array
#Making the Array
variable = ["Hello", "Nice", "Cool"]
#printing the array
print(variable)
array_of_fruits = ["Banana", "Apple", "Mango"]
#prints: ["Banana", "Apple", "Mango"]
array.append("Orange")
#prints: ["Banana", "Apple", "Mango", "Orange"]
