python打印各種三角形

color spa -i style bsp light int 倒三角 print

# 打印左下角三角形:for i in range(10):之後,range(0,i)
# 打印右上角三角形:在左下角的基礎上,將"-"變成" "空格
for i in range(10):
    for j in range(0,i):
        print("-",end=" ")

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

    print("")

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

  

# 打印左上角三角形:for i in range(10):之後,range(0,10-i)
# 打印右下角三角形:在左上角的基礎上,將"-"變成" "空格
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,只需要將"-",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("")
  1. 打印倒三角,只需要將"-",去掉
    for i in range(10):
        for j in range(0,i):
            print(end=" ")
    
        for j in range(i,10):
            print("$", end=" ")
    
        print("")
