python arrays

array = [1,2,3,4,5]
print(array,array[0],array[1],array[2],array[3],array[4]

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

how to create an array in python

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

how to make an array in python

#use numpy
import numpy #if you don't have it do pip install numpy
array = numpy.array(["Ford", "Volvo", "BMW"] )

arrays in python

#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

arrays python

array = [1, 2, 3, 4]

array.append(5)

for i in array:
  print(i)

array in python

#in python we consider lists to be arrays 
MyArray = ["Kathmandu", "Bardaghat", "Butwal", "Biratnagar"]
#array of places of Nepal
#we can print it by 
print(MyArray) 

arrays in python

# 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

how to make an array in python

#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 in python

# Python program to demonstrate
# Creation of Array
 
# importing "array" for array creations
import array as arr
 
# creating an array with integer type
a = arr.array('i', [1, 2, 3])
 
# printing original array
print ("The new created array is : ", end =" ")
for i in range (0, 3):
    print (a[i], end =" ")
print()
 
# creating an array with float type
b = arr.array('d', [2.5, 3.2, 3.3])
 
# printing original array
print ("The new created array is : ", end =" ")
for i in range (0, 3):
    print (b[i], end =" ")

what are arrays in python

#this is just for testing

how to make an array in python

array_of_fruits = ["Banana", "Apple", "Mango"]
#prints: ["Banana", "Apple", "Mango"]
array.append("Orange")
#prints: ["Banana", "Apple", "Mango", "Orange"]
