# Bill Splitter > Python script to split bills equally ## Introduction Imagine you go to a restaurant with four of your friends. The bill will be $105. You give $50 and others chip in $40, $10 and $5 and another friend dont have change so he didn't give. Bill should have been split $21 each way so now you need to calculate who owes howmuch to whom. This python script will solve this problem. The script takes contributions (individual share) to a bill and then gives who owes how much to whom with minimum number of transaction ## Usage Run the script.py ```bash cd bill_splitter python script.py ``` Enter the number of people among whom the bill is supposed to be split. eg: `2` ``` Number of participants : 2 ``` Enter the name of participant and his/her contribution to the bill separated by a space. eg: `John 50` ``` Enter name and contribution of participant 1 : John 50 Enter name and contribution of participant 2 : Travis 100 ``` Output ``` John paid $50 Travis paid $100 -------------------------------- Total pool amount : $150 Per head : $75.0 -------------------------------- John should pay $25.0 to Travis -------------------------------- ``` ## Conclusion The algorithm is designed in such a way that it will generate a result that has least number of transaction involved to achieve maximum efficiency. ## Author : Samartha | [@yunghog](https://github.com/yunghog)
