while循环语句
 
age = 50
guss_age = int(input("请输入您猜测的年龄:"))
while guss_age !=age:
    if guss_age > age:
        print("您猜大了:请重试!")
    else:
        print("您猜小了:请重试!")
    guss_age = int(input("请输入您猜测的年龄:"))
print("您猜对了!")
 
while 条件:
  .....
else:                #只有while语句里有break,else 语句才不会执行
  .....
 
break  终止
 
num =0
while  num     print(num)
    num = num +1
   
    break
 
continue跳出当次循环,继续从头开始
num = 1
while num    
    num = num +1
    if num == 3:
        continue
    print(num)
 
结果:
2
4
5
6
7
8
9
10
11
 
 
三行语句不换行
print("hallo word")
print("hallo word")
print("hallo word")
 
print("hallo word",end ="___")
print("hallo word",end ="___")
print("hallo word",end ="___")
 
num1 = 0
num2 = 0
while num1    print(num1,end="_")
    num2 = 0
    while num2         print(num2,end="-")
        num2+=1
    num1+=1
    print(end = "\n")    #等价于print()
 
结果:
0_0-1-2-3-4-5-6-7-
1_0-1-2-3-4-5-6-7-
2_0-1-2-3-4-5-6-7-
3_0-1-2-3-4-5-6-7-
4_0-1-2-3-4-5-6-7-
5_0-1-2-3-4-5-6-7-
