ID card number generation, verification code calculation, ID card number generation Verification Code

The second generation ID card number consists of 18 digits: 6-digit location code + 8-digit Date of Birth + 3-digit sequence code + 1-digit Verification Code

Here, the verification code is calculated as follows:

The first step is the ing weight; the second step is the product; the third step is the addition of the remainder; the last step is to find the code table to get the last 1 Character

The number in the red direction is smaller and the calculation speed is faster.

import random
import time

# Region code. This example only lists three characters.
Areas = ('20180101', '20180101', '20180101', '20180101 ')
# Top 17 weights of ID cards
W17 = (7, 9, 10, 5, 8,
4, 2, 1, 6, 3,
7, 9, 10, 5, 8,
4, 2)
# Check bit dictionary
Crc_dict = {0: '1', 1: '0', 2: 'X', 3: '9', 4: '8', 5: '7 ', 6: '6', 7: '5', 8: '4', 9: '3', 10: '2 '}


# Generating ID card numbers
Def create_zjhm ():
While True:
#6-digit Area
Zjhm = random. choice (areas)
#8-digit Date of birth
T_start = time. mktime (1970, 1, 1, 9, 0, 0, 0, 0 ))
T_end = time. mktime (1995, 1, 1, 9, 0, 0, 0, 0 ))
Random. randrange (start = t_start, stop = t_end)
Zjhm + = time. strftime ('% Y % m % d', time. gmtime (random. randrange (t_start, stop = t_end )))
#3-digit numerical order
Zjhm + = '% 03d' % random. randrange (start = 0, stop = 999)

#1-digit verification bit. the last verification bit is calculated based on the first 17-digit number. It can also be used for ID card verification.
# Multiply the sum by the weight and divide the sum by 11 for remainder.
Crc = sum (map (lambda z: z [0] * z [1], zip (w17, [int (I) for I in zjhm]) % 11
# Map Characters Based on the remainder
Crc = crc_dict.get (crc)
If not crc:
Time. sleep (1)
Continue

Zjhm + = crc
If not zjhm or len (zjhm )! = 18:
Time. sleep (1)
Continue

Return zjhm


If _ name _ = '_ main __':
Print (create_zjhm ())

The calculation result is as follows:
