[5,12]分割出数字

str1='139随机-[5,8]'

random_list = str1.split("随机-")

# 当输入为‘随机-[5,12]’时，随机从5-12中取数

if "[" in random_list[1]and "]" in random_list[1]:

__startUp =int(re.split("\[|,|\]", random_list[1])[1])

__endWith =int(re.split("\[|,|\]", random_list[1])[2]) #\[|,|\] 是按照“[”,",","]"分割

print(_startUp,_endWith)

str1 =str(random.randint(min(__startUp, __endWith),max(__startUp, __endWith)))#随机产生5-8之间任意位数：4535423
