当然，这段 JS 代码可以转换成 Python 代码，如下所示：

import hashlib
import random
import time

def getSignTime():
return int(time.time())

def calcSign(data, token, nonce):
del data['sign']
data_str = ''.join([key+str(value) for key,value in data.items()])
raw_str = f"{data_str}{token}{nonce}{data_str}"
sign = hashlib.sha256(raw_str.encode('utf-8')).hexdigest()
return sign.upper()

data = {"param1": "value1", "param2": "value2", "sign": "xxx"}
token = "a8a0cde0d32347b79fca1efaf2aff907"
nonce = "0000" + format(int(random.random() * pow(36, 4)), 'x')[-4:]
sign = calcSign(data, token, nonce)

print("nonce:", nonce)
print("sign:", sign)
print("signTime:", getSignTime())
