You can convert the lists you have into a dataframe df using pd.DataFrame and then use .dropna() to drop the rows that have nan values and then in the end use plt.scatter from Matplotlib to plot the scatter plot

import numpy as np
import matplotlib.pyplot as plt
import pandas as pd

Hp = [10050, 42300, 50206, np.nan, 105000, np.nan, 22350]
nr = [np.nan, 4,5,6,10,12,2]

df = pd.DataFrame({
        'Price':Hp,
        'Rooms':nr
        })
df = df.dropna(axis=0)

plt.scatter(x = df['Price'],y= df['Rooms'])
plt.xlabel('House Price')
plt.ylabel('Rooms')
