## while循环
基本语法：while 条件为true
代码块
while 1:
egon_age = 73
age = input('请输入你猜的年龄》》》')
age = int(age)
if age == egon_age:
print('猜对了')
elif age > egon_age:
print('猜大了')
elif age < egon_age:
print('猜小了')
请输入你猜的年龄》》》 23
猜小了
while 1:
egon_age = 73
age = input('请输入你猜的年龄》》》') # 73
age = int(age) # 73
if age == egon_age: # 成立
print('猜对了')
break
elif age > egon_age:
print('猜大了')
elif age < egon_age:
print('猜小了')
请输入你猜的年龄》》》 74
猜大了
请输入你猜的年龄》》》 73
猜对了
上方为while+break
while循环的嵌套
prize={0:'小红花',1:'大红花',2:'飞吻'}
while True:
egon_age=23
age=input('请输入您的猜测:')
age=int(age)
if age==egon_age:
while True:
print(f'猜对了,请选择您的礼物:{prize}')
choice=input('请选择你的礼物:')
choice=int(choice)
if choice==2:
print('不给\n请重新选择')
else:
print('给你')
break
break
elif age>egon_age:
print('大了')
elif age<egon_age:
print('小了')
while+continue
count = 1
while count < 101: # 1<101,2<101,count=50,
# if count != 50:
# print(count) # 1,2
# count += 1 # count=2,count=3
if count == 50:
count += 1
print('用不着')
continue # 不执行下面的代码
print(count) # 1,2
count += 1 # count=2,count=3
break直接终止整个while循环，
continue是终止本次循环，直接下一次循环。
