The absolute least required to make binance api requests in one function. everything is in this file and only pure python is needed. You can just scroll to bottom and create an apiGet('api/v1/etcetc') call and start parsing results without spending ten hours learning syntax and workarounds for some new python module (ccxt)

# the basic function. path is API path ( find em at https://binance-docs.github.io/apidocs/spot/en/ )
# params are any args to path
# sign = True/False, off by default. if hmac signing is required by path, then True it.
# timestamp = same as above. convenience to write True instead of int(time.time...
# recvWindow = usually required when 'sign' is.
# RETURNS: the result, or will throw exception and crash.

things become one(ish)-liners now pretty quickly:

# easily get current BTC price.
btcPrice = apiGet('api/v3/avgPrice',params={'symbol':'BTCUSDT'})
print(btcPrice['price'])

#all 'assets' that we have a positive balance in
accts = apiGet('api/v3/account',params={},sign=True,timestamp=True,recvWindow=True)
for i in accts['balances']:
    if float(i['free']) > 0 or float(i['locked']) > 0:
        print(i['asset'])
