For below I am using a Haberman's Dataset & LINK FOR DATASET - https://www.kaggle.com/gilsousa/habermans-survival-data-set/version/1
df_1 = df.loc[df["survival_status"] == "1"]; #here ,I have put this "1" is from dataset,1 means survive ,means 1 is a dependent variable
df_2 = df.loc[df["survival_status"] == "2"]; #here ,I have put this "2" is from dataset,2 means not survive, means 2 is a dependent variable
counts,bin_edges=np.histogram(df_1["age"],bins=10,density=None)
pdf=counts/(sum(counts))
print(pdf)
print(bin_edges)
cdf=np.cumsum(pdf)
plt.plot(bin_edges[1:],pdf)
plt.plot(bin_edges[1:],cdf)
plt.show()
I am getting below error

I am trying to create a PDF & CDF and I am getting this above TypeError.
