请问大佬们，这个输出为什么不正确？

已采纳

如果这个代码中b=3,m=1的话不是应该输出60吗，为什么会输出62呢？

for yue in range(1,b):
        if yue==1 or 3 or 5 or 7 or 8 or 10 or 12:
            yuezongshu=yuezongshu+31
        elif yue==4 or 6 or 9 or 11:
            yuezongshu=yuezongshu+30
        else:
            if m==1:
                yuezongshu=yuezongshu+29
            else:
                yuezongshu=yuezongshu+28
    print(yuezongshu)

 if yue in [1, 3, 5, 7, 8 , 10 , 12]:
 或者
 if yue==1 or yue==3 or yue==5 or yue==7 or yue==8 or yue==10 or yue==12:

yuezongshu = 0
for yue in range(1,b):
    if yue in [1,3,5,7,8,10,12]:
        yuezongshu = yuezongshu+31
    elif yue in [4,6,9,11]:
        yuezongshu = yuezongshu+30
