extend方法可用于将一个数组的元素添加到另一个数组的末尾。对于两个JSON数组,我们可以将一个数组的元素逐个添加到另一个数组中,从而实现合并。 以下是使用extend方法合并两个JSON数组的示例代码: importjson array1=json.loads('[1, 2, 3]')array2=json.loads('[4, 5, 6]')array1.extend(array2)merged_...

如果给定一个列表或字符串,该 initializer 会被传给新数组的fromlist(),frombytes()或fromunicode()方法(见下文)以将初始条目添加到数组中。 否则会将可迭代对象作为 initializer 传给extend()方法。 引发一个审计事件array.__new__附带参数typecode,initializer。
