Why do i see TypeError

The TypeError appeared because you are using a parameter which is not available for the Python function you are using.

In most cases, the TypeError in Pandas occurs in two different cases:
1. you made a typo
2. you are using a parameter that was available in older versions of the Pandas function you are using, but is no longer available and you cannot use it

How to fix TypeError

There are several ways to fix TypeError in Pandas.

• Check the spelling and correct any typos.
• Use another parameter that is available for the function you are using.
• Use another function that offers the parameter you want.
• Use another python module, for example Numpy. Pandas isn’t the only Python module you can use.
• Write your own function in python.
• Check the documentation for the function or method you are calling and ensure that you are passing valid arguments.
