在循环中使用条件语句时,需要确保循环执行的次数是明确的,以便在循环结束后可以准确地知道循环执行了多少次。以下是一些建议:
counter = 0
while some_condition:
# do something
if some_condition:
counter += 1
counter = 0
for i in range(some_range):
# do something
if some_condition:
counter += 1
values = [1, 2, 3, 4, 5]
counter = 0
for value in values:
# do something
if some_condition:
counter += 1
data = [1, 2, 3, 4, 5]
counter = 0
for item in iter(data):
# do something
if some_condition:
counter += 1
counter = 0
while some_condition:
# do something
if some_condition:
counter += 1
break
通过以上方法,可以确保循环中的条件语句执行的次数是明确的,并且可以在循环结束后准确地知道条件语句执行了多少次。
