Python GraphQL Client - Unexpected punctuator when passing variables

Question

Code:

contract="0xdAC17F958D2ee523a2206206994597C13D831ec7"

query = """
($contract: Int!) {
 token(id:$contract){
   name
   symbol
   decimals
   derivedETH
   tradeVolumeUSD
   totalLiquidity
 }
}
"""

variables = {
    "contract": contract
}

data = client.execute(query=query, variables=variables)

Error:

{'errors': [{'locations': [{'column': 1, 'line': 2}], 'message': 'Unexpected `([Punctuator]`\nExpected `{`, `query`, `mutation`, `subscription` or `fragment`'}]}

I've tried reformatting a number of ways and I cannot get this error to go away! Help!

Your GraphQL query must start with a query:

query($someVar: String!) {
  someQuery(someArg: $someVar) {
     ...
  }
}

Why does my query work exactly as above without variables? If I simply remove "($contract: Int!)" and change token(id:$contract) to token(id: "0x00...etc") everything runs fine – Marcus Mar 11 '21 at 17:29
This did fix it! I'm just curious why it works without "query" if I do not include variables. – Marcus Mar 11 '21 at 17:36

@Marcus Without variables, most GQL clients send the `query` prefix implicitly – Icebreaker454 Mar 11 '21 at 17:45
Fantastic! Thank you! – Marcus Mar 11 '21 at 18:01
