Take the public key, SHA256 it, RIPEMD-160 it, then add 0x00 to the start. Call this pubhash_prefix. SHA256 this twice, take the first 4 bytes, and then append these 4 bytes to pubhash_prefix. Convert to base58 and you have your address.

The same thing as described by o_e_l_e_o, this time in python code:

Code:

bin = binascii.unhexlify(public_key)

#Step 1: Create hash of public key:
hash_of_public_key = hashlib.sha256(bin).digest()

#Step 2: Calculate RIPEMD-160 of the public key:
r = hashlib.new('ripemd160')
r.update(hash_of_public_key)
r.hexdigest()

#Step 3: Adding network bytes (00) to RIPEMD-160
networked = binascii.unhexlify('00'+r.hexdigest())

#Step 4: Double hash the networked RIPEMD-160
sha4a = hashlib.sha256(networked).digest()
sha4b = hashlib.sha256(sha4a).digest()

#Step 5: Get the first four bytes of sha4b:
four_bytes = str(binascii.hexlify(sha4b).decode('utf-8'))[:8]

#Step 6: Adding the four_bytes to the end the RIPEMD-160 from step 3:
address_hex = str(binascii.hexlify(networked).decode('utf-8')) + four_bytes

#Step 7: Convert the hex_address using base58 to bitcoin adres
address_base58 = base58.b58encode(binascii.unhexlify(address_hex))
