打印（）结果未输出，找不到错误

Question

这个脚本生成了一个散列，但是它没有在函数中正确地写入某些内容

from bitcoin import *
import os
import hashlib
import base58
 

while True:
    priv =  random_key()
    pubkey = privtopub(priv)
    compress_pubkey = False
    
 
    if (compress_pubkey):
        if (ord(pubkey[-2:].decode('hex')) % 2 == 0):
            pubkey_compressed = '02'
        else:
            pubkey_compressed = '03'
        pubkey_compressed += pubkey[2:66]
        hex_str = bytearray.fromhex(pubkey_compressed)
    else:
        hex_str = bytearray.fromhex(pubkey)
 
key_hash = hash160(hex_str)

def hash160(hex_str):
    sha = hashlib.sha256()
    rip = hashlib.new('ripemd160')
    sha.update(hex_str)
    rip.update( sha.digest() )
    print ( "key_hash = \t" + rip.hexdigest() )
    return rip.hexdigest()  # .hexdigest() is hex ASCII

我检查了脚本是否正常工作。没有print (pubkey)。结果将显示公钥，但我不需要获取密钥散列。不幸的是，当我这样做的时候print ("key_hash = \ t" + rip.hexdigest ())

结果没有执行！我不懂编程。帮助修复代码

重新排列代码后：

from bitcoin import *
import os
import hashlib
import base58

def hash160(hex_str):
    sha = hashlib.sha256()
    rip = hashlib.new('ripemd160')
    sha.update(hex_str)
    rip.update(sha.digest())
    print("key_hash = \t" + rip.hexdigest())
    return rip.hexdigest()  # .hexdigest() is hex ASCII

while True:
    priv = random_key()
    pubkey = privtopub(priv)
    compress_pubkey = False

    if (compress_pubkey):
        if (ord(pubkey[-2:].decode('hex')) % 2 == 0):
            pubkey_compressed = '02'
        else:
            pubkey_compressed = '03'
        pubkey_compressed += pubkey[2:66]
        hex_str = bytearray.fromhex(pubkey_compressed)
    else:
        hex_str = bytearray.fromhex(pubkey)

    key_hash = hash160(hex_str)

输出：

key_hash =  b0ac6f690633331af487f594dd3c42c6c67ce085
key_hash =  de735b3046545f63c8cb2f7d44b7f24a8b769ad7
key_hash =  49b0ae2b541832797680b977ca9e374d1a621787
key_hash =  ea3e1d9762331e791412e96b2a67f418cfd6ca2c
key_hash =  e5ff3affd4ba7eb2bb343548f587bde9dbdace6b
key_hash =  b1a952405516abe494e7e32610a3eaf85d7914f2
key_hash =  a0050e1f18b2d0738c458e237a447bd8f2810fec
key_hash =  23eeca93355ba511bdf28c475b5e62d2da64546b
key_hash =  cc5904bae39ee51b75097c95ad0307a21ecef1bc
... And So On

注意，有一个无限循环（^ {CD1>}），考虑用特定的迭代次数替换。
