I'm working in Python and I suck at building arrays. I keep getting an error that says "ValueError: length of values does not match length of index?". I need to find a forum about this error message or something that can help me figure out what I'm doing wrong.

The ValueError: Length of values does not match length of index raised because the previous columns you have added in the DataFrame are not the same length as the most recent one you have attempted to add in the DataFrame. So, you need make sure that the length of the array you are assign to a new column is equal to the length of the dataframe. Another solution is that you first convert the list/array to a pandas Series , and then when you do assignment, missing index in the Series will be filled with NaN values .
