url = ("https://etherscan.io/address/%s" % address)
                                         ^

You're missing the % to assign the variable. Alternatively you can use other forms of string formatting:

Using .format()

url = "https://etherscan.io/address/{}".format(address)

Using f strings:

url = f"https://etherscan.io/address/{address}"
