The AttributeError: 'Series' object has no attribute 'to_list'

The error occurs when you try to call the to_list() method on a pandas Series object, but the method is not available in the version of pandas you are using. This method was added in pandas version 0.24.0, so if you are using an earlier version of pandas, you will get this error.

To fix this error, you can either upgrade your pandas version to 0.24.0 or later, or you can use an alternative method to convert the Series object to a list. Here are some examples:

1. Using the tolist() method: If you are using pandas version 0.17.0 or later, you can use the tolist() method instead of to_list(). For example:

.

import pandas as pd

# Create a pandas Series object

s = pd.Series([1, 2, 3, 4, 5])

# Convert the Series object to a list

lst = s.tolist()

print(lst)

# Output: [1, 2, 3, 4, 5]

..

2. Using the values attribute: If you are using pandas version 0.24.0 or later, you can also use the values attribute to get a numpy array, and then convert the array to a list using the tolist() method. For example:

.

import pandas as pd

# Create a pandas Series object

s = pd.Series([1, 2, 3, 4, 5])

# Convert the Series object to a list

lst = s.values.tolist()

print(lst)

# Output: [1, 2, 3, 4, 5]

..

3. Using the list() function: If you are using an earlier version of pandas and the above methods do not work, you can use the built-in list() function to convert the Series object to a list. For example:

.

import pandas as pd

# Create a pandas Series object

s = pd.Series([1, 2, 3, 4, 5])

# Convert the Series object to a list

lst = list(s)

print(lst)

# Output: [1, 2, 3, 4, 5]

..
