解析：
常见的优惠券(激活码)是由数字、字母(大小写)组成；
string.ascii_letters 26个大小写字母；
string.digits 0-9数字；
随机组合 使用random.sample
import random
import string code = string.ascii_letters + string.digits
print(code) #获取随机生成的4位字符串
def getCode():
return "".join(random.sample(code, 4))
print(getCode()) #获取4列4位激活码 以"—"串联起来
def key(group):
return "—".join([getCode() for i in range(group)])
print(key(4)) #获取200组激活码 每组4列4位
def keys(n):
return "\n".join([key(4) for i in range(n)]) print(keys(200))
