求解
>>> first = 3>>> second = 8
>>> third = firet + second
Traceback (most recent call last):
File "<pyshell#6>", line 1, in <module>
third = firet + second
NameError: name 'firet' is not defined
>>> print(third)
Traceback (most recent call last):
File "<pyshell#7>", line 1, in <module>
print(third)
NameError: name 'third' is not defined
请问这是什么问题 第三行是first，不是firet 要学会根据报错信息找错误
