else:
上面循环里的语句正常走完了后，才执行这里的语句

再次优化一下猜年龄小程序
1 #!/usr/bin/env python 2 # -*- coding:utf-8 -*- 3 # Author:Hiuhung Wan 4 age_of_MrWang = 48 5 for i in range (3): 6 guess_age = int(input("Enter the age of Mr Wang:")) 7 if guess_age == age_of_MrWang: 8 print("Yes,you got it!") 9 break 10 elif guess_age < age_of_MrWang: 11 print("Think bigger!") 12 else: 13 print("Think smaller!") 14 else: 15 print("You have tried too many times...Fuck off!")
range里可以设置，默认是1
#!/usr/bin/env python
# -*- coding:utf-8 -*-
# Author:Hiuhung Wan
for i in range(0,10,2): #步长是2
print("loop",i)
