如何使用函数打印扇区树？

class Sector:
    def __init__(self, name, subsectors=None):
        self.name = name
        self.subsectors = subsectors or []

def print_sector_tree(sector, indent=0):
    print(" " * indent, sector.name)
    for subsector in sector.subsectors:
        print_sector_tree(subsector, indent + 2)

# 构建一个扇区树的示例
root = Sector("Root")
sector1 = Sector("Sector 1")
sector2 = Sector("Sector 2")
subsector1 = Sector("Subsector 1")
subsector2 = Sector("Subsector 2")
subsector3 = Sector("Subsector 3")
subsector4 = Sector("Subsector 4")
subsector5 = Sector("Subsector 5")

root.subsectors = [sector1, sector2]
sector1.subsectors = [subsector1, subsector2]
sector2.subsectors = [subsector3, subsector4, subsector5]

# 打印扇区树
print_sector_tree(root)
