python实现单条及用户指定条横线的打印——函数

#打印一条线
def hengxian():
 print("-"*30)
hengxian()

#打印用户指定条横线
def hengxian():
 print("-"*30)

# hengxian()
#多的东西要想到循环
# def duotiaohengxian(x):
# print(hengxian() * x)
# a = int(input("请输入打印次数"))
# duotiaohengxian(a)

def duotiao(x):
 for i in range(0,x):
 hengxian()
a = int(input("请输入横线条数："))
duotiao(a)
