Day 4

List :

Previously I have discussed that,

A list is a sequential data type

1. An ordered collection of data

2. It is mutable.

3. It's an abstract data type.

Let's solve a few problems on the list :

1. Write a python program to reverse a list

l=[34,76,23,11]
print(l[::-1])

output:

this is the easiest way to solve the reverse list by using the slicing operator.

1. Write a python program to find out the length of the list

l=[3,6,3,4]
print(len(l))

output :

These are the basic code that I have solved by listing, using keywords.

1. Write a Python program to print all negative numbers in a range.

n=int(input("enter the first number"))
m=int(input("enter the second number"))
print([i for i in range(n,m+1) if i<0])

Output:

Here are some basic questions on the list:

In my next blogs, you will get to know about loops and their uses.

Thank you.
