while循环
1、输出打印以#组成的长方形，自己定义长和宽。
# -*-encoding:utf-8-*-
‘‘‘
This is script for start docker containor!
Auth: cuishuai
‘‘‘
height = int(input("Height:"))
width = int(input("Width:"))
num_height = 1
while num_height <= height:
num_width = 1
while num_width <= width:
num_width += 1
print("#",end="")
num_height += 1
print()
2、输出如下图形
*
* *
* * *
* * * *
# -*-encoding:utf-8-*-
‘‘‘
This is script for start docker containor!
Auth: cuishuai
‘‘‘
width = int(input("Width:"))
num_width = 1
while num_width <= width:
print("#"*num_width,end="\n")
num_width += 1
3、输出2的倒叙图形：
* * * *
* * *
* *
*
# -*-encoding:utf-8-*-
‘‘‘
This is script for start docker containor!
Auth: cuishuai
‘‘‘
width = int(input("Width:"))
while width > 0:
print("#"*width,end="\n")
width -= 1
第二种实现方式，使用嵌套循环：
# -*-encoding:utf-8-*-
‘‘‘
This is script for start docker containor!
Auth: cuishuai
‘‘‘
width = int(input("Width:"))
while width > 0:
num_width = width
while num_width > 0:
print("*",end="")
num_width -= 1
print()
width -= 1
5、输出99乘法表
# -*-encoding:utf-8-*-
‘‘‘
This is script for start docker containor!
Auth: cuishuai
‘‘‘
width = 1
while width <= 9:
num_width = 1
while num_width <= width:
print(str(num_width)+"*"+str(width)+"="+str(num_width*width),end="\t")
num_width += 1
print()
width += 1
倒叙99表
# -*-encoding:utf-8-*-
‘‘‘
This is script for start docker containor!
Auth: cuishuai
‘‘‘
width = 9
while width > 0:
num_width = 1
while num_width <= width:
print(str(num_width)+"*"+str(width)+"="+str(num_width*width),end="\t")
num_width += 1
print()
width -= 1
注释：end=表示每一行的结尾，\n表示换行符，\t表示制表符
