Designated digit randomly generated PIN

import random
import string

# 方法一：
def code_1(m, choice):
 code=''.join(random.sample(choice, m))
 return code

print(code_1(4, string.ascii_letters + string.digits))

# 方法二：
def code_2(n):
 code=''
 for i in range(n):
 number=random.randint(0, 9) # 0-9
 lower_char=chr(random.randint(97, 122)) # a-z
 upper_char=chr(random.randint(65, 90)) # A-Z
 char_1=random.choice([number, lower_char, upper_char])
 code+=str(char_1)
 return code

print(code_2(4)

First the code. . . As I ^ ^ efficient ... Discolored, do not mind ha ~
