为什么打印0而不是5?
我找不到我的逻辑错误?
score = 0
def pass_score(test_string, aScore):
if re.match(a, test_string):
increase_score(5, score)
print (aScore)
def increase_score (aValue, aScore):
aScore += aValue
最佳答案
没有全局变量的第一种方法返回值:
def increase_score (aValue, aScore):
aScore += aValue
return aScore
def pass_score(test_string, aScore):
if re.match(a, test_string):
aScore = increase_score(5, aScore)
print (aScore)
第二种方法,使用global var:
score = 0
def increase_score (aValue): #don't need to receive score, I've it.
global score
score += aValue
def pass_score(test_string):
global score
if re.match(a, test_string):
increase_score(5)
print (score)
我想您需要两者兼而有之。无论如何,此时您的代码看起来有点脏,混合了本地变量和全局变量。
