萌新问题

请问为什么会出现这种情况（跟着up主做，在github上查看源码都一样啊）
五子棋算法 #问题应该在主函数
main.py
from game import Gomoku
import sys
def main():
g = Gomoku()
g.play()
if _name_ == '_main_':
main()
run main.py之后的显示
D:\pycharm\FFFFF\venv\Scripts\python.exe D:/pycharm/FFFFF/main.py
Traceback (most recent call last):
File "D:/pycharm/FFFFF/main.py", line 10, in <module>
if _name_ == '_main_':
NameError: name '_name_' is not definedProcess finished with exit code 1
刚学python希望能有大佬指点
附game.py
game.py：
