在python中是否已经生成了包含仅使用数字的强随机序列的包？

Question

我在python中使用uuid包生成随机代码,但它使用数字和字符.在python中是否已经生成了包含仅使用数字的强随机序列的包？(目前我有两个选项来生成序列(36位),方法是通过调用random()或将字符转换为数字来生成每个数字,但如果这是足够随机的话,我不会这样做.

Python返回的uuid实际上是一个类,因此您可以轻松地以不同的格式获取它:

>>> import uuid
>>> uuid.uuid4().int
27168693431722041803402778536822837233

这是UUID类型的在线帮助.你想要这个int属性.

Help on class UUID in module uuid:

class UUID(builtins.object)
 |  Instances of the UUID class represent UUIDs as specified in RFC 4122.
 |  UUID objects are immutable, hashable, and usable as dictionary keys.
 |  Converting a UUID to a string with str() yields something in the form
 |  '12345678-1234-1234-1234-123456789abc'.  The UUID constructor accepts
 |  five possible forms: a similar string of hexadecimal digits, or a tuple
 |  of six integer fields (with 32-bit, 16-bit, 16-bit, 8-bit, 8-bit, and
 |  48-bit values respectively) as an argument named 'fields', or a string
 |  of 16 bytes (with all the integer fields in big-endian order) as an
 |  argument named 'bytes', or a string of 16 bytes (with the first three
 |  fields in little-endian order) as an argument named 'bytes_le', or a
 |  single 128-bit integer as an argument named 'int'.
 |  
 |  UUIDs have these read-only attributes:
 |  
 |      bytes       the UUID as a 16-byte string (containing the six
 |                  integer fields in big-endian byte order)
 |  
 |      bytes_le    the UUID as a 16-byte string (with time_low, time_mid,
 |                  and time_hi_version in little-endian byte order)
 |  
 |      fields      a tuple of the six integer fields of the UUID,
 |                  which are also available as six individual attributes
 |                  and two derived attributes:
 |  
 |          time_low                the first 32 bits of the UUID
 |          time_mid                the next 16 bits of the UUID
 |          time_hi_version         the next 16 bits of the UUID
 |          clock_seq_hi_variant    the next 8 bits of the UUID
 |          clock_seq_low           the next 8 bits of the UUID
 |          node                    the last 48 bits of the UUID
 |  
 |          time                    the 60-bit timestamp
 |          clock_seq               the 14-bit sequence number
 |  
 |      hex         the UUID as a 32-character hexadecimal string
 |  
 |      int         the UUID as a 128-bit integer
 |  
 |      urn         the UUID as a URN as specified in RFC 4122
 |  
 |      variant     the UUID variant (one of the constants RESERVED_NCS,
 |                  RFC_4122, RESERVED_MICROSOFT, or RESERVED_FUTURE)
 |  
 |      version     the UUID version number (1 through 5, meaningful only
 |                  when the variant is RFC_4122)
 |
