# [SOLVED] Converting an integer to a sequence of letters using a function

## Issue

I want to create a function that takes an integer (say 234) and returns it as letters (cde).

I have managed to form some code that takes the number and separates it into its numeric components

``````def toLetter(n):
x = str(n)
for elem in x:
print(elem)
d = {0 : 'a', 1 : 'b', 2 : 'c', 3 : 'd', 4 : 'e', 5 : 'f', 6 : 'g', 7 : 'h', 8 : 'i', 9 : 'j'}
for n in x:
d[n]

toLetter(234)
``````

But I am really struggling with;

1. how to map the dictionary onto the number and
2. get it to return it as:
``````cde
``````

rather than

``````c
d
e
``````

Any help would be greatly appreciated. I am new so this may be trivial but I have come here as last resort.

## Solution

So, in order to select the elements in the dictionary you have to convert the digits back to integers. Also, to create the final answer I would simply append each letter to a string and print the final string:

``````def toLetter(n):
d = {0 : 'a', 1 : 'b', 2 : 'c', 3 : 'd', 4 : 'e', 5 : 'f', 6 : 'g', 7 : 'h', 8 : 'i', 9 : 'j'}

x = str(n)
result = ''

for elem in x:
result = result + d[int(elem)]

print(result)

toLetter(234)
``````

Output:

``````cde
``````
