object is not iterable

“object is not iterable”是Python中常见的错误之一，意思是对象不可迭代。在Python中，只有实现了__iter__()方法的对象才是可迭代的，如果一个对象没有实现__iter__()方法，那么它就不是可迭代的。当我们尝试对一个不可迭代的对象进行迭代操作时，就会出现“object is not iterable”的错误。解决这个错误的方法是检查代码中是否有对不可迭代对象进行了迭代操作，或者检查对象是否实现了__iter__()方法。如果对象没有实现__iter__()方法，可以考虑实现该方法使其变为可迭代对象。

js object is not iterable

If you are getting the error "js object is not iterable", it means that you are trying to iterate over an object using a loop or a higher-order function that expects an iterable, such as `for...of` loop, `forEach()`, `map()`, or `spread operator (...)`.

In JavaScript, objects are not directly iterable. However, you can iterate over the keys or values of an object using a `for...in` loop or by using `Object.keys()`, `Object.values()`, or `Object.entries()` methods.

Here's an example of how you can iterate over the keys or values of an object:

const obj = { key1: 'value1', key2: 'value2', key3: 'value3' };

// Iterate over keys
for (const key in obj) {
  console.log(key);
}

// Iterate over values
for (const value of Object.values(obj)) {
  console.log(value);
}

// Convert object to array of key-value pairs and iterate
const entries = Object.entries(obj);
for (const [key, value] of entries) {
  console.log(key, value);
}

Make sure to use the appropriate method or loop based on your specific use case.

type object is not iterable

这意味着尝试将不可迭代对象当做可迭代对象使用。可迭代对象是指能够被循环遍历的对象，如列表、字符串、元组等。如果尝试对不可迭代对象使用 `for ... in ...` 语句，会出现这个错误。请检查代码是否使用了正确的对象，或者将不可迭代对象转换为可迭代对象。
