Why is it giving the error-cannot concatenate a non-NDFrame object

The fill function is to fill all the non-available data in titanic with the average age of that particular class of passengers

titanic['Age']=titanic[['Age','Pclass']].apply(fill,axis=1) 

sex=pd.get_dummies(titanic['Sex'],drop_first=True)

embarked=pd.get_dummies(titanic['Embarked'],drop_first=True)

titanic.drop(['Cabin','Embarked'],axis=1,inplace=True)

titanic.dropna(inplace=True)

titanic=pd.concat(['titanic','sex','embarked'],axis=1)

I think you mean:

titanic=pd.concat([titanic,sex,embarked],axis=1)

instead of:

titanic=pd.concat(['titanic','sex','embarked'],axis=1)

A side note however:
If you're just trying to drop NaN values and get dummies you can do it on the original dataframe without having to use pandas.concat.

example:

titanic = pd.get_dummies(titanic)

and just drop NaN values with dataframe.dropna:

titanic.dropna(inplace=True)

Hope this was helpful.

pd.concat expects you to give list of dataframe as parameter not a list of strings. Change your code to 

titanic=pd.concat([titanic,sex,embarked],axis=1)
