how to figure out the number of decimals?

[chiwalfrm]

Using the method get_token_balance(address=my_address) to get the token balance for an address, the output does not take into account the number of decimals. For example:
fetching USDC (contract address 0xdac17f958d2ee523a2206206994597c13d831ec7) token balance returns a number that needs to be divided by 1e+6 (i.e. 6 decimal places):

Result: {"status":"1","message":"OK","result":"87000000000"} --> actual value = 87,000

But for many other tokens, it needs to be divided by 1e+18:
For example, for aWETH (contract address 0x030ba81f1c18d280636f32af80b9aad02cf0854e):

Result: {"status":"1","message":"OK","result":"200004568518412516545"} --> actual value = 200.004568518412516545

Question is how can we know the divisor / i.e. how many decimals is in the result?

I figured out how to do it with Infura:

from ethtoken.abi import EIP20_ABI
from web3 import Web3
infurakey = 'YOUR_INFURA_API_KEY'
value = 'TOKEN_CONTRACT_ADDRESS'
w3 = Web3(Web3.HTTPProvider('https://mainnet.infura.io/v3/' + infurakey))
address2 = w3.toChecksumAddress(value)
contract = w3.eth.contract(address2, abi=EIP20_ABI)
print(contract.functions.decimals().call())

Closing this issue.
