Al ejecutar esto:
print("promedio",notas["nota"].mean()) print("mediana",notas['nota'].median())
Me arroja el error: TypeError Traceback (most recent call last) in <cell line: 1>() ----> 1 print("promedio",dfnotas["nota"].mean()) 2 print("mediana",dfnotas['nota'].median())
TypeError: 'str' object is not callable
