字典的常用操作方法和函数如下：

d = {1:["东方延续","太空军自然选择号舰长","女","33"],2:["章北海","太空军自然选择号政委","男","39"],3:["罗辑","太空军自然选择号远通发射长","男","24"],
}
print(d)
d[4]=["丁仪","太空军自然选择号动力工程师","男","46"]
print(d)#获取键值集合
print("获取键值集合")
keys=list(d.keys())
print("keys=list(d.keys()):",keys)
values=list(d.values())
print("values=list(d.values()):",values[1][1])print("d.pop(1)方法将key值为1的元素剪切出来了",d.pop(1)) #.pop()方法将ken值对应的元素剪切出来了
print("d.pop(1)后剩下的d",d)print(d.pop(5,"此键值不存在"))
lst1=[i for i in range(10)]
lst2=[i*i for i in range(10)]
d = dict(zip(lst1,lst2))
print(d)
print("d.popitem()随机从字典中选取一对key-value键值对剪切掉",d.popitem()) #随机从字典中选取一对key-value键值对，剪切掉
print(d)d.clear()
print(d)
