python - ValueError: Must have equal len keys and value when setting . . . With loc, you have to assign a value that matches the length of the item you're assigning to, and since 1!=3, it throws an error So one way to get around is: test['b'] = [[5,6,7]] * len(test) where the length of test matches the length of the list being assigned (because [5,6,7] is multiplied by len(test)) I'm a bit slow to comprehend your answer
Pandas中使用可迭代对象进行设置时必须保证键和值的长度相等|极客教程 为了避免“ValueError: Must have equal len keys and value when setting with an iterable”错误，我们需要明确指定可迭代对象的长度，以便与DataFrame或Series的长度相匹配。
ValueError: Must have equal len keys and value when setting . . . - GitHub df loc [1, 2] = np zeros (3) The loc assign throws a "ValueError: Must have equal len keys and value when setting with an iterable" despite dtypes being object for column 2 This started to happen when I updated Pandas from 1 4 4 -> 2 2 1 In 1 4 4 this syntax worked
Must have equal len keys and value when setting with iterable The Pandas "ValueError: Must have equal len keys and value when setting with an iterable" occurs when you incorrectly iterate over a DataFrame to try to set column values To solve the error, use the DataFrame apply() method Here is an example of how the error occurs df loc[i, 'coords'] = ['X', 'Y']
Python Pandas: Solving ValueError: Must have equal len keys and value . . . The ValueError: Must have equal len keys and value when setting with an iterable in Pandas typically arises from attempting to assign an iterable (like a list) to a single DataFrame cell using df loc [] in a loop, where Pandas' alignment rules for iterables and scalar targets conflict
Must have equal len keys and value when setting with an iterable 2: An error related to this one ValueError: Must have equal len keys and value when setting with an ndarray occurs if the object being assigned is a numpy array and there's a shape mismatch That one is often solved either using np tile or simply transposing the array
Pandas中的“Must have equal len keys and value when setting with an . . . 在本文中，我们将介绍Pandas中的“Must have equal len keys and value when setting with an iterable”。 这是一个常见的错误，当我们使用Pandas中的iterable来设置DataFrame时出现。 具体来说，如果我们尝试通过一个iterable来设置Pandas DataFrame的某一列时，如果iterable的长度与DataFrame的长度不同，就会出现这个错误。 看一个错误示例很容易理解这个错误。 假设我们有一个Pandas DataFrame: 现在我们想将列A设置为一个长度为两个元素的列表： 这个时候我们就会得到下面的错误： 出现这个错误的原因是因为我们尝试用一个长度为2的列表来覆盖一个长度为3的列。
Must have equal len keys and value when setting with an iterable . . . ValueError: Must have equal len keys and value when setting with an iterable I don't know what's causing this problem The strangest of all is that the script doesn't actually fail every time I run it but only sometimes (???) Also, is there perhaps a more elegant pythonic way to do what I am trying to do?
