Python builtins 模块，hex() 实例源码
我们从Python开源项目中，提取了以下6个代码示例，用于说明如何使用builtins.hex()。
def flatten_source_post_id(cls, source_post_id, extra_length=0):
# Ensure that a source_post_id can be used as part 1 of message_id
sanitized = cls._non_email_chars.subn(
lambda c: '_' + hex(ord(c.group()))[2:], source_post_id)[0]
if len(sanitized) + extra_length > 64:
# 64 is max according to RFC 5322
# cut it short and add a digest of original
import hashlib
import base64
d = hashlib.md5()
d.update(source_post_id)
d = base64.urlsafe_b64encode(d.digest())
sanitized = sanitized[
:max(0, 64-len(d)-extra_length-1)]
if sanitized:
sanitized += "_" + d
else:
sanitized = d
