Study 6 —— while循环

Posted 2020-10-13 yancy.lu

语法
while 条件：
　　执行代码。。。

1. #从0打印到100，每循环一次 +1

count = 0

while count <= 100 :
print(‘Loop: ‘, count)
count += 1

2. #打印从1到100的偶数

count = 1

while count <= 100 :	
if count % 2 == 0 :
print(‘Even: ‘, count)
count += 1

3. #循环打印1-100，第50次不打印值，第60-80次打印对应值的平方

count = 1

while count <= 100:
if count == 50:
pass
elif count >= 60 and count <= 80:
print(‘Value: ‘, count ** 2)
else:
print(‘Value: ‘, count)	
count += 1

4. 死循环

count = 0
while True:
print(‘Value‘, count)
count += 1
