installation

pip install cfx-address

use Base32Address class methods

from cfx_address import Base32Address

validate a base32 address

Base32Address.is_valid_base32("0x1ecde7223747601823f7535d7968ba98b4881e09") 
# False
Base32Address.validate("0x1ecde7223747601823f7535d7968ba98b4881e09")
# will raise an exception

encode and decode

# encode hex address to base32
Base32Address.encode_base32("0x1ecde7223747601823f7535d7968ba98b4881e09", network_id=1)
#'cfxtest:aatp533cg7d0agbd87kz48nj1mpnkca8be1rz695j4'

# decode base32 address
