python array

#Getting input for array from user
from array import *

a = array("i",[])

n = int(input("Enter the length of array "))

for i in range(n):
    x = int(input("Enter the next value "))
    a.append(x)

print (a)

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

python array

array = ["1st", "2nd", "3rd"];
#prints: ['1st', '2nd', '3rd']

python array

import random

ary = [8, 7, 1, 67, 77, 108, 801, 800, 777, 131, 414]
new_array = random.sample(ary, len(ary) )

for items in range(100):
  print(random.sample(ary, len(new_array)))

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
"""

Python array

array('l')
array('u', 'hello u2641')
array('l', [1, 2, 3, 4, 5])
array('d', [1.0, 2.0, 3.14])

python array

array = [2, 54, 5, 7, 8, 9]
#printing wole array
print(array)
#it will print whole array

#printing  any one array will be like this
print(array[0])
#it will print 2

print(array[2])
#it will print 5

print(array[1])
#it will print 54
#and so on...

how to make an array python

#arrays and lists are different
#numpy arrays are faster
this_is_a_list = [1, 2, 3]
import numpy #is you do not have it do pip install numpy
this_is_an_array = numpy.array([1, 2, 3])

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 =" ")
