Often times we have 100+ columns in the dataset and we have to find out how many columns are numeric and ultimately count of the columns

```
numerics = ['int16', 'int32', 'int64', 'float16', 'float32', 'float64']
numeric_df = df.select_dtypes(include=numerics)
len(numeric_df.columns)
```

Here, the first line creates a list of all the data types having numeric values and saves them into a variable called `numerics`

then `numeric_df`

variable stores column for elements stated in `numerics`

variable.

Simply, in the last, we are using the simple `len function`

to calculate the number of columns.
