This is a set of two programs that use the mendeleev python library (https://github.com/lmmentel/mendeleev/) to do the following:

1. string_to_num.py asks the user for a string and encodes it(if possible) to a sequence of numbers. The numbers are atomic numbers of the chemical element symbols extracted from the input string.

For example: if the user enters "SUPER", the program outputs ["16 92 15 68"] where each number corresponds to an element from the periodic table ( [S U P Er] in this case).

2. num_to_string.py does the opposite of the first program and encodes a number to a string by converting the atomic numbers extracted from the number to the chemical symbols.

For example: if the user enters "1234", the program outputs ['HHeLiBe', 'HHeSe', 'HVBe', 'MgLiBe', 'MgSe']. These are all the possible combinations of elements whose atmoic numbers, taken in order, will give back the original number.

This was just a fun exercise to write a program for something we used to do by pen and paper in our chemistry class in high school.

You need python3 and preferably virtualenv to run the code.

git clone https://github.com/aniansh19019/PeriodicTable_Encoder_Decoder
cd PeriodicTable_Encoder_Decoder
virtualenv -p python3 .env
source .env/bin/activate
pip install -r requirements.txt

use python num_to_string.py and python string_to_num.py to run the programs.
