我有一个if语句，它有3个要求。
if (-30 < distancey1_1 < 30) and (german_startx1 < 705) and (distance1_1 < 600) : # is german 1 in position and are the russians in range (between 30 and minus 30 doesnt work)
print(distancey1_1)
print('1_shoots_1')
shoot(bulletx1, bullety1, 10, 10, yellow)
即使不满足所有3个要求，它也会以某种方式运行此if语句。
我有时将此作为输出。基本上是承认忽略-30 这是一个愚蠢的小娱乐活动的一部分，目的是让敌人从大门口的那个场景中消失。 完整代码如下。它只是使正方形向侧面移动，其中一些会射击。 我怎样才能让它仅在满足所有3个条件时才执行if语句？1 shoots 1
