# Code Walkthrough: `remove_liquidity_one_coin` In this lesson, we'll be walking through the function `remove_liquidity_one_coin`. This function allows a liquidity provider to specify which token they want their liquidity withdrawn in. The function takes the following inputs: `token_amount`: This is the amount of LP shares the liquidity provider wishes to burn. ```javascript token_amount: uint256, ``` `i`: This is the index of the coin that they want to withdraw their liquidity in. ```javascript i: uint256, ``` Let's take a look at the function. First, the code calculates `A` and `gamma`. ```javascript A_gamma: uint256[2] = self._A_gamma() ``` Next, the code initializes some variables: ```javascript dy: uint256 = 0 D: uint256 = 0 p: uint256 = 0 xp: uint256[N_COINS] = empty(uint256[N_COINS]) approx_fee: uint256 = 0 ``` Then, the internal function `claim_admin_fees()` is called. ```javascript self._claim_admin_fees() ``` After that, the code calls `calc_withdraw_one_coin` to calculate the amount of token that will go out `dy`. ```javascript dy, D, xp, approx_fee = self._calc_withdraw_one_coin( A_gamma, token_amount, i, (self.future_A_gamma_time > block.timestamp) ) ``` The code then checks that `dy` is greater than or equal to the `min_amount`, which was specified by the caller. ```javascript assert dy >= min_amount, "Slippage" ``` Next, the token balances are updated. Since only one token is exiting the pool, we only need to update the balance for the token that is going out. ```javascript self.balances[i] -= dy ``` The code burns the LP tokens from the message sender for the amount of `token_amount`. ```javascript self.burnFrom(msg.sender, token_amount) ``` The code transfers the token out. ```javascript self._transfer_out(coins[i], dy, use_eth, receiver) ``` The code calls the internal function `tweak_price` to adjust prices. ```javascript packed_price_scale: uint256 = self.tweak_price(A_gamma, xp, D, 0) ``` An event is logged, and the amount of token that was transferred out is returned. ```javascript log RemoveLiquidityOne( msg.sender, token_amount, i, dy, approx_fee, packed_price_scale ) return dy ```
