四：Python的while循环

while循环:

 while count<10:
      print(count)
        #count=100
        count=count+1
        
      print(123)

while循环break:终止所有循环

count=0
while count<10:
               count=count+1
               print(count)
           break
           print(1111111)
print('end')

while循环continue:终止当前循环，开启下面循环

count=0
while count<10:
    if count==7:
    count=count+1
    countinue

    print(count)
    count=count+1
