#while循环
'''
while 条件语句
功能
重点：
while的掌握
break (结束循环)
continue (跳过本次循环，直接执行下一个循环)
pass (占位符主要用于写函数的时候测试用)

#for循环
#主要用于获取遍历
#使用for循环拿出字符串中的内容
# var = "今天，我感觉很累，一会早点休息了"
# for val in var:
# print(val)
#使用for循环拿出列表的内容
# list1=["今天","很累","呢"]
# for var in list1:
# print(var)
#使用for循环拿出元组的内容
# var = ("明天","希望","变好")
# for val in var:
# print(val)
#使用for循环拿出集合的内容
# var = {1,2,3,5}
# for val in var:
# print(val)
#使用for循环拿出字典的内容
# dict1 = {"今天":"晚上","我在":"代码","好累":"好爽"}
# for var in dict1: (这个方法是取出字典中的主键)
# print(var)
#下面我们来取出这个字典中的值
# var1 = {"yes":"nod","abc":"123","cde":"456"}
# for val in var1:
# print(val)
# print(var1.values())
# for val in var1.values():
# print(val)
# var = {"a":1,"b":2,"c":3}
# for val in var:
# print(val)
# print(var.values())
# for val in var.values():
# print(val)
# for key,value in var.items():
# print(key,value)
# dict1 = {"a":"1","b":"2","c":"3"}
# for key,value in dict1.items():
# print(key,value)
# dict1 = {"a":"1","b":"2","c":"3"}
# for val in dict1:
# print(val)
# print(dict1.values())
# var = {"a":"1","b":"2","c":"3"}
# for key,value in var.items():
# print(key,value)
#----------------------------------
# dict = {"我":"感觉","好":"累","真的":"好累"}
# for var,val in dict.items():
# print(var,val)
#设置一个字典，要求拿出字典中的值
# dict1 = {"a":"1","b":"2"}
# for var in dict1.values():
# print(var)
#设置一个字典要求拿出字典中的主键和值
# a = {"asd":"asdd","asddd":"asdddd"}
# for key,value in a.items():
# print(key,value)
#设置一个字典要求拿出他的主键然后在拿出他的值
# dict1 = {"a":"1","b":"2","c":"3"}
# for var in dict1:
# print(var)
# print(dict1.values())
# var = {"today":"is","good":"day"}
# for val in var:
# print(val)
# print(var.values())
# var = {"abc":"123","cde":"456"}
# for key,value in var.items():
# print(key,value)
# var = ["c++","java","python"]
# for val in var:
# print(val)
# for res in val:
# print(res)
# var = {"a":"1","b":"2"}
# for val in var:
# print(val)
# print(var.values())
# var = {"name":"yangyang","name2":"yangyang2"}
# for val,res in var.items():
# print(val,res)
# var = [[1,2,3],[4,5,6],[7,8,9]]
# for val in var:
# print(val,type(val))
# for res in val:
# print(res)
# for a,b,c in var:
# print(a,b,c)
#range()形成一个序列
# res = range(1,10)
# for var in res:
# print(var)
# for i in range(1,10):
# for j in range(1,i+1):
# print("%sx%s=%s"%(j,i,j*i),end=" ")
# print()
# for i in range(1,10):
# for j in range(1,i+1):
# print("%s*%s=%s"%(j,i,j*i),end=" ")
# print()
# for i in range(1,10):
# for j in range(i,10):
# print("%s*%s=%s"%(j,i,j*i),end=" ")
# print()
# for i in range(1,10):
# for k in range(1,10-i):
# print(end = " ")
# for j in range(1,i+1):
# print("%sx%s=%s"%(j,i,j*i),end="\t")
# print()
#.items(参数，取出字典中的所有内容，键值都拿出来)
# var = {"a":"b","c":"d"}
# for val in var.items():
# print(val)
#当然如果字典中的值都是一样的，可以直接设置两个值来拿出来
#显示起来更加的直观
#使用两个变量进行接收
# dict1 = {"a":"1","b":"2"}
# for var,val in dict1.items():
# print(var,val)
#range()
#生成一个序列，（容器）
#用法： 变量名 = range() :括号里面写需要的字符，默认从0开始，但可以自定义起始字符
#使用9*9表
#等一一个i，然后定义一个序列，数字从1-9，然后依次拿出里面的内容
# for i in range(1,10):
#然后定义一个j，也定义一个序列，他的序列从1开始，到i+1结束，
#j的循环是1，i+1，那么i每次都是1，2，3这样循环，j的循环结束每次都比i多1
#所以数据从i进来，i的值为1，然后进行内循环，内循环j的值先开始为1，所以往下走，i=1，j=1，1*1=1，之后在进行循环，因为j循环中的值并没有被循环完，i+1嘛，所以j的值是2，内循环还可以继续循环，所以就是1*2=2，之后j的值没了，循环随之结束，换行，之后在进行外部循环，这次i的值在进行循环拿出2，然后依次进行循环
# for j in range(1,i+1):
# print("%s*%s=%s"%(j,i,j*i),end=" ")
# print()
# for i in range(1,10):
# for j in range(i,10):
# print("%s*%s=%s"%(j,i,j*i),end=" ")
# print()
# for i in range(1,10):
# for j in range(1,i+1):
# print("%s*%s=%s"%(j,i,j*i),end=" ")
# print()
# for i in range(1,10):
# for k in (1,10-i):
# print(end=" ")
# for j in range(1,i+1):
# print("%s*%s=%s"%(j,i,j*i),end="\t")
# print()
# count = 0
# sum1 = 0
# while count < 101:
# sum1 += count
# count +=1
# print(sum1)
# height = 100
# sum1 = 0
# while True:
# if height < 1:
# sum1 -= height
# break
# else:
# sum1 += height + height/2
# height /= 2
