Hi everyone,

I am playing around with some old code from online and am getting an error:

for dataset in train_test_data:
    dataset.loc[ dataset['Age'] <= 16, 'Age'] = 0,
    dataset.loc[(dataset['Age'] > 16) & (dataset['Age'] <= 26), 'Age'] = 1,
    dataset.loc[(dataset['Age'] > 26) & (dataset['Age'] <= 36), 'Age'] = 2,
    dataset.loc[(dataset['Age'] > 36) & (dataset['Age'] <= 62), 'Age'] = 3,
    dataset.loc[ dataset['Age'] > 62, 'Age'] = 4

ValueError: Must have equal len keys and value when setting with an iterable

Does anyone know how to assign conditional values in pandas?

Thanks
Scott

you must elaborate, there's not enough information here.
what are the error codes?
what does train_test_data structure look like, etc.
Also, code needs to be a snippet that can be run, or at least, one where all inputs and outputs are visable.

Hi,

here is the complete code in github. It was written by someone years ago and I'm guessing there has been some changes to python since then.

If you run this script you'll get the same error at the point in code above.

Thanks

This code was written using Iron python link here
There shouldn't be any massive changes since 2017.
I present this link as an aid.
