2. 使用*输出长方形，长宽由用户输入
long = int(input("请输入长度（整数）：")) weight = int(input("请输入宽度（整数）：")) i = 1 while i <= weight: j = 1 while j <= long: print("*",end="") j += 1 i += 1 print("") long = int(input("请输入长度（整数）：")) weight = int(input("请输入宽度（整数）：")) i = 1 while i <= long: print("* " * weight) i += 1
3.用*打印三角形
1）打印直角三角形
# 利用字符串运算符 num = int(input("请输入整数：")) i = 1 while i <= num: print("* " * i) i += 1 num = int(input("请输入整数：")) i = 1 while i <= num: j = 1 while j <= i: print("*", end=" ") j += 1 i += 1 print("")输出：
2）倒序三角形，相减即可
3）直角在这边
# 利用字符串运算符 num = int(input("请输入整数：")) i = 1 while i <= num: str = "*" * i print(" " * (num - i), end=str) i += 1 print("")
