如何在Julia中将字典值设置为零

# 创建一个字典
my_dict = Dict("key1" => 1, "key2" => 2, "key3" => 3)

# 将字典中的值设置为零
my_dict["key1"] = 0
my_dict["key2"] = 0
my_dict["key3"] = 0

# 打印修改后的字典
println(my_dict)

Dict("key2" => 0, "key3" => 0, "key1" => 0)

# 创建一个字典
my_dict = Dict("key1" => 1, "key2" => 2, "key3" => 3)

# 将字典中的值设置为零（使用get函数）
my_dict["key1"] = get(my_dict, "key1", 0)
my_dict["key2"] = get(my_dict, "key2", 0)
my_dict["key3"] = get(my_dict, "key3", 0)
my_dict["key4"] = get(my_dict, "key4", 0)

# 打印修改后的字典
println(my_dict)

Dict("key2" => 2, "key3" => 3, "key4" => 0, "key1" => 1)
