DataFrame.Append deprecated and need to be replaced by pandas.concat.

DataFrame.Append:
def check_state_exist(self, state):
if state not in self.q_table.index:
self.q_table = self.q_table.append(
pd.Series(
[0]*len(self.actions),
index=self.q_table.columns,
name=state,
)
)

Pandas.Concat:
def check_state_exist(self, state):
if state not in self.q_table.index:
self.q_table = pd.concat([self.q_table,
pd.Series(
[0]*len(self.actions),
