Question

Challenge.

• Create a function named 'a' that takes a string as parameter and returns a new string after converting it to lowercase.

Character limit - less than 12 characters.

Language - Python. ​

Answer 1

Language:

Python

Program:

def a(string):

   if len(string)<12:

       new=""

       for i in string:

           new+=i.lower()

       return new

   else:

       return None

Examples of input output:

print(a("HELLO")) #outputs hello

print(a("CS"))    #outputs cs

Explanation:

• str.lower() method returns a set lowercase string.
• Since strings are immutable you want change their values instead you'll have to make a new indentifier.

Answer 2

Answer:

String s;

System.out.println ("Enter string");

s=sc.next();

int l=s.length();

for (int a=0;a<=l-1;a++)

{

char ch=s.charAt(0);

(String)d=d+ch;

}

d=d.toLowerCase();

System.out.println (d);

This one I have written in Java.

This will prove as a pathway to write in PYTHON.

Only the format needs to be changed but the processes are all same.
