Python basics tutorial pandas dataframe reset index method

sure! i'd be happy to provide you with a tutorial on the `reset_index()` method in pandas dataframe in python.

### tutorial: pandas dataframe `reset_index()` method

the `reset_index()` method in pandas dataframe is used to reset the index of the dataframe. when you reset the index, the current index will be moved to a new column and the dataframe will be given a new default integer index starting from 0.

#### syntax:

- `level`: this parameter is used to specify the level in a multiindex to be reset. default is none.
- `drop`: if true, the old index will be dropped, otherwise, it will be kept in a column in the dataframe. default is false.
- `inplace`: if true, modify the dataframe in place. default is false.
- `col_level`: if the columns have multiple levels, determines which level the index is reset to. default is 0.
- `col_fill`: when the columns have multiple levels, determines how the other levels are named. default is an empty string.

#### example:
let's create a sample dataframe and demonstrate the usage of `reset_index()` method:

#### output:

in this example, we first set the 'name' column as the index of the dataframe using `set_index()` method. then we used the `reset_index()` method to reset the index, which moved the 'name' column back as a regular column and added a default integer index.

i hope this tutorial helps you understand how to use the `reset_index()` method in pandas dataframe in python! let me know if you have any questions.
