#三角形

for i in range(10):
    for j in range(0,i):
        print("-",end=" ")

    for j in range(i,10):
        print("$", end=" ")

    print("")

print("-------------------------")

for i in range(10):
    for j in range(0, 10 - i):
        print("-", end=" ")
    for k in range(10 - i, 10):
        print("$", end=" ")

    print("")

打印上三角，只需要将"－"去掉

for i in range(10):
    for j in range(0, 10 - i):
        print(end=" ")
    for k in range(10 - i, 10):
        print("$", end=" ")

    print("")

打印倒三角，只需要将"－",去掉

for i in range(10):
    for j in range(0,i):
        print(end=" ")

    for j in range(i,10):
        print("$", end=" ")

    print("")
