I get the same error whenever I want to run my code.

Traceback (most recent call last):
  File "paises.py", line 1, in <module>
    from pandas import DataFrame, Series
  File "/home/david/Documents/Projetos/Intro to Data Science/pandas.py", line 1, in <module>
    from pandas import DataFrame
ImportError: cannot import name DataFrame

My code is:

from pandas import DataFrame

Another Error:

Traceback (most recent call last): 
  File "knowingPandas.py", line 1, in <module>
    import pandas as pd
  File "/home/david/Documents/Projetos/Intro to Data Science/pandas.py", line 1
