spot_client.ticker_price() doesn't work

[KaiserPygit]

Hi,

I'm simply trying the following to get used to this library :

from pymexc import spot

api_key = 'abc'
api_secret = 'def'

spot_client = spot.HTTP(api_key = api_key, api_secret = api_secret)

print(spot_client.account_information())

print(spot_client.ticker_price())

Everything works fine until the last line. I have 2 problems here :

• I didn't fully understand how to pass the arguments for a specific ticker, for example BTCUSDT

• biggest problem : even if I try it with no argument, the doc says ":param symbol: (optional) If the symbol is not sent, all symbols will be returned in an array." So I should at least get an array as return, but instead I get the following error which I don't understand :

During handling of the above exception, another exception occurred:

What's wrong ?

Fixed. Seems like when request sent to public endpoint with sign it return zero-content response.

Thanks, it works now :)
However I'm still struggling to pass the argument for a specific ticker.
For example I tried spot_client.ticker_price('symbol': 'BTCUSDT') but it says invalid syntax and if I try spot_client.ticker_price({'symbol': 'BTCUSDT'}) it says invalid symbol. What's the syntax to use ?
I also tried using '=' instead of ':' but nothing works.

EDIT : nevermind I found it, it's spot_client.ticker_price(symbol = 'BTCUSDT'), I was a bit stupid on this one
