My code is

def search(n):
    lis = []
    pad = {1: ['.', ',''?', '!', ':'], 2: ['A', 'B', 'C'], 3: ['D', 'E', 'F'], 4: ['G', 'H', 'I'], 5: ['J', 'K', 'L']
        , 6: ['M', 'N', 'O'], 7: ['P', 'Q', 'R', 'S'], 8: ['T', 'U', 'V'], 9: ['W', 'X', 'Y', 'Z'], 0: ' '}
    for i in n:
        for key,values in pad.items():
            if i.upper() in values:
                lis.append(key)
    return lis


def main():
     m = input("Enter String")
     print(search(m))
main()

my output is

Enter String - hello world
[4, 3, 5, 5, 6, 0, 9, 6, 7, 5, 3]

It gives output as the single key only. However I want output as [44,33,555,555,666,9,666,777,555,3]

>Solution :

This is because you after you find the key, you only append the key once.

You will need to add the logic to duplicate the key string several times.

I only added one line and modified one line of your original code. Hope this helps.

    lis = []
    pad = {1: ['.', ',''?', '!', ':'], 2: ['A', 'B', 'C'], 3: ['D', 'E', 'F'], 4: ['G', 'H', 'I'], 5: ['J', 'K', 'L']
        , 6: ['M', 'N', 'O'], 7: ['P', 'Q', 'R', 'S'], 8: ['T', 'U', 'V'], 9: ['W', 'X', 'Y', 'Z'], 0: ' '}
    for i in n:
        for key, values in pad.items():
            if i.upper() in values:
                temp = str(key) * (values.index(i.upper()) + 1)  // added
                lis.append(temp)   // modified
    return lis


def main():
     m = input("Enter String")
     print(search(m))
main()
