请问一下为什么while没有进行循环
也没有执行else后面的加法运算
谢谢！！
代码：
while True:
first_number = input("Please input the first_number:")
a = first_number
second_number = input("Please input the second_number:")
b = second_number
if a or b == 'q':
break
else:
try:
add_number = int(a) + int(b)
except ValueError:
print("Please input right data type!")
else:
print(add_number)
结果：
Please input the first_number:12
Please input the second_number:24
Process finished with exit code 0
if a or b == 'q':这里有问题
if a or b=="q"
这里改为
if a=="q" or b=="q"
if语法写错了哈
