user21732: Yesterday I made a transaction from my one btc address to another by using pybitcointools library for blockchain api. I made a mistake by making input value 10x times higher than output value.
So I have a quesiton: Is that input minus output value treated as fee now, or can I restore it back in some way ?
Here is link transaction history ( only 1 transaction ) where you can see what's going on : https://blockchain.info/address/1Fno6XBjLbEq53oTG6MWw1X1vA2hbyaLPh?format=json
and here is transaction's blockchain link:

user21052: Yes, the difference between the input and the output is the transaction fee, and there's no way for you to get it back once it has been mined (except for building a fork that results in a stronger chain---not likely unless you have >50% of network hash rate).
In the future, I highly recommend experimenting on testnet (bitcoind -testnet) or using regtest mode.  That way you don't lose any wealth when you make a mistake.
