just a typo

**typo** = print(df_transport,5)
**fix** = print(df_transport)

**reasoning**
- typo just prints the number five after the database
- does not match JupyterLab notebook

**more information**
- code does not need to specify five rows, as pd defaults to this
- to change the default, you can use:
**pd.set_option('display.max_rows', 10)**
- otherwise, you can be more specific using head() and tail()
**print(df_transport.head(3))**
**print(df_transport.tail(7))**
