The first aspect to take into account when booking your online Python classes is your level. The lower it is, the less you will need to spend to get to a basic level.
On the other hand, if you already know some Python and want to master this programming language, the more expensive tutors are more suitable for you. There are also other things to consider before hiring a tutor. For example, flexibility of schedule is a key factor..
So is your field of specialisation, as learning Python is a skill that applies to a wide range of programming fields. For example, if you want to take private Python classes to learn backend development, a tutor who is an expert in web design will be more suitable.
