想用python打一个这样的函数出来怎么做啊？应该用用for

*\n**\n***\n****\n*****\n
format 很难用得上

temp = input(“请输入数字：”)
number = int(temp)
i = 1
while number:
print("*" * "i")
i = i + 1
number = number - 1
#纯小白，求大神指正

num = int(input("请输入一个大于1的正整数"))
for i in range(1, num):
for j in range(1, i+1):
print("*", end = '')
print("\n")
