英文:
After printing a range I'm getting 100+ instances. Is there a way how many numbers were printed in that range before break?
问题
for i in range(1000):
my_ticket = random.randint(1, 1000)
if my_ticket % 100 == 0:
break
else:
print(my_ticket)
我正在尝试解决Eric Matthes书中包括的"Python crash course"中的彩票分析问题。我试图找出我获得指定数字的概率。
英文:
for i in range(1000):
my_ticket = random.randint(1, 1000)
if my_ticket % 100 == 0:

你的迭代器已经在跟踪数量，break 会结束循环，所以你只需要直接在此之前打印 i。
if my_ticket % 100 == 0:
print(i)
break
英文:
Your iterator is already tracking how many, the break ends the loop so all you have to do is literally print i immediately prior.
if my_ticket % 100 == 0:
print(i)
break

你可以在 for 循环之前使用一个计数变量 c。
每次进入 else 语句时，它将增加1。
import random
c = 0
for i in range(1000):
my_ticket = random.randint(1, 1000)
if my_ticket % 100 == 0:
break
else:
c += 1
print(my_ticket)
print("打印的总数: ", c)
英文:
You can use a counter variable c before the forloop.
Everytime it goes to else it will increase by 1
import random
c=0
for i in range(1000):
my_ticket = random.randint(1, 1000)
if my_ticket % 100 == 0:
break
else:
c+=1
print(my_ticket)
print("Total numbers printed: ", c)
