Python Array

 26/4

## Python Array[ ]

- Collection of similar elements is called array.



##  Types of Array Separator:-

1. comma(,) is called variable separator.

2. { } block separator used in looping and condition

3. ( ) function separator

4. [ ] array separator


example:- 

car = ["maruti","indica","swift"]

print(car)

output:- ['maruti', 'indica', 'swift']



## Access array elements

car = ["maruti","indica","swift"]

x = car[0]

print(x)

output:- maruti



## Modify array element

car = ["maruti","indica","swift"]

car[0] = "swiftD'zire"

print(car)

output:- ['swiftD'zire', 'indica', 'swift']



## Find the length of array

car = ["maruti","indica","swift"]

x = len(car)

print(x)

output:- 3



## Using for loop in array concept

car = ["maruti","indica","swift"]

for x in car:

    print(x)

output:- 

maruti

indica

swift



## Adding new element in array

car = ["maruti","indica","swift"]

car.append("honda")

print(car)

output:- ["maruti","indica","swift","honda"]



 ## How to remove array element

car = ["maruti","indica","swift"]

car.pop(1)

print(car)

output:- ["maruti","swift"]



## Remove array element with name

car = ["maruti","indica","swift"]

car.remove("swift")

print(car)

output:- ["maruti","indica"]



## Sort array element

car = ["maruti","indica","swift"]

car.sort()

print(car)

output:- ['indica', 'maruti', 'swift']



## Reverse array element

car = ["maruti","indica","swift"]

car.reverse()

print(car)

output:- ['swift', 'indica', 'maruti']



## Count array element

car = ["maruti","indica","swift","maruti"]

x = car.count("maruti")

print(x)

output:- 2  (bcoz here maruti is written 2 times)



## Copy array element

car = ["maruti","indica","swift","maruti"]

x = car.copy()

print(x)

output:- ['maruti', 'indica', 'swift', 'maruti']



## Insert array element

car = ["maruti","indica","swift","maruti"]

car.insert(1,"honda")

print(car)

output:- ['maruti', 'honda', 'indica', 'swift', 'maruti']



## Clear the array element

car = ["maruti","indica","swift","maruti"]

car.clear()

print(car)

output:- [ ]



## User input array

listA = [ ]

n = int(input("enter the no. of element"))

for i in range(0,n):

    print("enter element")

    ele = int(input())

    listA.append(ele)

    

print("the element of list A \n ", listA)

output:- enter the no. of element 4

4

enter element

3

enter element

6

enter element

2

enter element

5

the element of list A 

  [3, 6, 2, 5]


example:- 

toys = [ ]

n = int(input("enter the no. of toys "))

for i in range(0,n):

    print("toy position")

    num = int(input())

    toys.append(num)

    

print("list of toys are \n ", toys)   

output:- 

enter the no. of toys 6

toy position

5

toy position

8

toy position

2

toy position

5

toy position

9

toy position

4

list of toys are 

  [5, 8, 2, 5, 9, 4]



Task:-   WAP to input 5 no. user choice and store the array 

(here we've fixed the range that is why it'll take upto 5 no. only) 

toys = [ ]                                                                      (empty array of  toy)
n = int(input("enter the no. of toys "))                        (user will insert the value at runtime)
for i in range(5):                                                          (condition applied)
    print("toy position")                                                (it will ask the user at runtime to enter the value)
    num = int(input())                                                    (num variable will store the entered value)
    toys.append(num)                                                    (this will add the new values to the toy array)
    
print("list of toys are \n ", toys)                                   (will print toy array with values that have entered)

OUTPUT:- 
enter the no. of toys 5
toy position
8
toy position
2
toy position
9
toy position
7
toy position
4
list of toys are 
  [8, 2, 9, 7, 4]


Rough example:-
toys = [4,7,9,1,8,3]

n = int(input("enter the no. of toys "))

for i in range(5):

    print("toy position")

    num = int(input())

    toys.append(num)

    

print("list of toys are \n ", toys)  
 
output:-
enter the no. of toys 5
toy position
0
toy position
2
toy position
6
toy position
7
toy position
9
list of toys are 
  [4, 7, 9, 1, 8, 3, 0, 2, 6, 7, 9]
