1. Write a program to create one array from
another array.
from array import *
a1=array('i',[1,2,3,4,5])
a2=array(a1.typecode, (a for a in a1))
print(a1)
print("The program created from another array")
print(a2)
2. Create a program
to retrieve, display and update only a range of
elements from an array using indexing and slicing
in arrays.
from array import *
x= array('i',[1,2,3,4,5,6,7,8,9,10])
#Slicing
y=x[2:4]
print('slicing',y)
x[0]=5
print('updated array', x)
3. Write a program to understand various
methods of array class mentioned: append, insert,
remove, pop, index, tolist and count.
from array import *
a=array('i',[1,2,3,4,5])
print("Original array ",a)
a.append(10)
a.append(20)
print("After appending 10 and 20 the array is ",a)
x=int(input("Enter no. u want to count from
array"))
print("The occurance of ",x ,"is
",a.count(x))
b=array('i',[6,7,8,9])
a.extend(b)
print("The array after extending b" , a)
print("The index position of 5 in array " ,
a.index(5))
a.insert(0,11)
print ("Insert 11 at 0 the position in array ", a)
a.pop()
print("The array after pop function", a)
a.pop(6)
print("The array after 5 value poped ", a)
a.remove(8)
print("The array after removed value 4", a)
a.reverse()
print("The array after reverse function ",a)
lst=a.tolist()
print("The array converted to list ",lst)
4. Write a program to sort the array elements
from array import *
x=array('i',[])
n=int(input("Enter the size of array"))
for i in range(n):
x.append(int(input("Enter element")))
for i in range(n):
print(x[i])
#print(x)
j=i+1
for j in
range(n):
if
a[i]>a[j]:
t=a[i]
a[i]=a[j]
a[j]=t
print("After sorting",a)
5. Create a program to search the position of an element in an array using
index() method of array class.
from array import *
x=array('i',[])
n=int(input("Enter the size of array"))
for i in range(n):
x.append(int(input("Enter element")))
for i in range(n):
print(x[i])
ind=int(input("Enter element"))
try:
pos=x.index(ind)
print("Element
found at ",pos)
except ValueError:
print("Element not found")
