Convert_one_to_hex missing from python pyhmy?

tabasco_ow · November 17, 2021, 2:03am

Hi, I’ve been looking for a way to convert a one address to a checksum ETH(hex) address, and attempted to utilize pyhmy.util to do this, although it seems in all my attempts convert_one_to_hex is missing from util. Util has the rest of the functions found within the github source code(get_gopath, is_active_shard, etc.) though lacks this specific one; so when trying to import it directly an error is thrown.

It’s likely a fault on my end but I was wondering if any of you guys knew anything about this before I moved forward, thanks!

The function to convert is here:

              """
              return subprocess.check_output(["go", "env", "GOPATH"]).decode().strip()
          
          

          
def get_goversion():
              """
              :returns The go-version, assuming that go is installed.
              """
              return subprocess.check_output(["go", "version"]).decode().strip()
          
          
def convert_one_to_hex(addr):
              """
              Given a one address, convert it to hex checksum address
              """
              if not is_valid_address(addr):
                  return to_checksum_address(addr)
              hrp, data = bech32_decode(addr)
              buf = convertbits(data, 5, 8, False)
              address = '0x' + ''.join('{:02x}'.format(x) for x in buf)
              return to_checksum_address(address)

I am not sure what the issue is but feel free to post your error.

There is a dependency of eth_utils that is required…

          )
          
          
from .bech32.bech32 import (
              bech32_decode,
              convertbits
          )
          
          
from eth_utils import to_checksum_address
          
          
datetime_format = "%Y-%m-%d %H:%M:%S.%f"
          
          
class Typgpy(str):
              """
              Typography constants for pretty printing.
          
          
    Note that an ENDC is needed to mark the end of a 'highlighted' text segment.
              """
              HEADER = '\033[95m'

Did you install it?

Turns out pip installs an incomplete pyhmy, so thats why it lacks convert_one_to_hex, so manually installing it through git seemed to fix the issue.

That’s great to hear… There was some updates done recently. I guess pip is not uptodate!
