Series' object has no attribute 'Substring'

It seems like you are trying to use the `Substring` attribute on a Series object, but it is not a valid attribute for that object. The `Substring` method is not available directly on a Series object in Python.

If you want to extract a substring from a Series object, you can use the `str` accessor followed by the desired string method. For example, if you have a Series called `my_series` and you want to extract a substring from each element, you can use the `str.slice` method:

my_series.str.slice(start, stop)

Replace `start` and `stop` with the desired indices for your substring.

Alternatively, if you want to apply a substring operation on each element of the Series, you can use the `apply` method with a custom lambda function:

my_series.apply(lambda x: x[start:stop])

Again, replace `start` and `stop` with the desired indices for your substring.
