I have got through all of the data anaylsis with python course except for this one error I keep getting on this project that I cant solve.
FAIL: test_heat_map_values (test_module.HeatMapTestCase)
Traceback (most recent call last):
File “/home/runner/boilerplate-medical-data-visualizer-4/test_module.py”, line 47, in test_heat_map_values
self.assertEqual(actual, expected, “Expected differnt values in heat map.”)
AssertionError: Lists differ: [’’, ‘’, ‘’] != [‘0.0’, ‘0.0’, ‘-0.0’, ‘0.0’, ‘-0.1’, ‘0.5’[615 chars]0.1’]
First differing element 0:
Second list contains 88 additional elements.
First extra element 3:
Diff is 951 characters long. Set self.maxDiff to None to see it. : Expected differnt values in heat map.
It seems like the list the test produces for comparison is not populating with any values at all. I have tried for a few days now to solve it but I am completely stumped. My code for the heatmap is as follows:
def draw_heat_map(): # Clean the data dfclean = df[df['ap_lo'] <= df['ap_hi']] dfclean = dfclean[dfclean['height'] >= dfclean['height'].quantile(0.025)] dfclean = dfclean[dfclean['height'] <= dfclean['height'].quantile(0.975)] dfclean = dfclean[dfclean['weight'] >= dfclean['weight'].quantile(0.025)] dfclean = dfclean[dfclean['weight'] <= dfclean['weight'].quantile(0.975)] # Calculate the correlation matrix corr = dfclean.corr() # Generate a mask for the upper triangle mask = np.triu(np.ones_like(corr, dtype=bool)) # Set up the matplotlib figure fig, ax = plt.subplots() # Draw the heatmap with 'sns.heatmap()' ax = sns.heatmap(corr, mask=mask) # Do not modify the next two lines fig.savefig('heatmap.png') return fig
I would greatly appreciate any help with resolving this so I can finish the course!

Thanks in advance.
