Python Lab Manual / Lists in Python Program

Program Name

Write a Python Program for Lists.

Theory

Lists are used to store multiple items in a single variable. Lists can be sort,display, modify and delete.

Program Code


#List Array
print("List Array")
l=list(map(int,input("Enter array elements:").split()))
for i in l:
    print("List Array Elements",i)


#Delete element from list
print("\nDelete element from list")
a=list(map(int,input("Enter Numbers:").split()))
e=int(input("Enter the element to delete"))
for i in range(0,len(a)):
    if(a[i]==e):
        for j in range(i,len(a)-1):
            a[j]=a[j+1]
        a[j+1]=None
print(a)


#Sort list
print("\nSort list")
b=list(map(int,input("Enter Numbers:").split()))
for i in range(0,len(b)-1):
    for j in range(0,len(b)-1):
        if(b[j+1]<b[j]):
            b[j],b[j+1]=b[j+1],b[j]
print(b)


#Print element less than given(key) element
print("\nPrint element less than given(key) element")
c=list(map(int,input("Enter array elements:").split()))
e=int(input("Enter a number:"))
for i in range(0,len(c)):
    if(c[i]<e):
        print(c[i],end=" ")

Input:
List Array
Enter array elements:1 2 3 4
List Array Elements 1
List Array Elements 2
List Array Elements 3
List Array Elements 4

Delete element from list
Enter Numbers:1 2
Enter the element to delete1
[2, None]

Sort list
Enter Numbers:4 2 3 1
[1, 2, 3, 4]

Print element less than given(key) element
Enter array elements:1 2 3 4
Enter a number:3
1 2

Output:
List Array
Enter array elements:1 2 3 4
List Array Elements 1
List Array Elements 2
List Array Elements 3
List Array Elements 4

Delete element from list
Enter Numbers:1 2
Enter the element to delete1
[2, None]

Sort list
Enter Numbers:4 2 3 1
[1, 2, 3, 4]

Print element less than given(key) element
Enter array elements:1 2 3 4
Enter a number:3
1 2
