Medical Data - not running doesn’t seem to run. It starts then nothing happens for ages and it says it is running. I also can’t get it to print a chart. I thought my code was wrong, so I copied someone else’s that was complete and working to try that to see if it is the code or not. It still didn’t work.

I don’t know what to do. I had this issue with the calculator too. I wrote it in PyCharm and it worked perfectly, but I had major issues with It’s really dishartening. I stopped for weeks because of it and I’ve only started again.

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

# Import data
df = pd.read_csv('medical_examination.csv')

# Add 'overweight' column
df['overweight'] = df['weight']/np.square((df['height'])/100).astype(int)

#assign 1 to >25 values and 0 to rest

df['overweight'] = df['overweight'].apply(lambda x : 1 if x > 25 else 0)

# Normalize data by making 0 always good and 1 always bad. If the value of 'cholestorol' or 'gluc' is 1, make the value 0. If the value is more than 1, make the value 1.

df['cholesterol'] = df['cholesterol'].apply(lambda x : 0 if x == 1 else 1)
df['gluc'] = df['gluc'].apply(lambda x : 0 if x == 1 else 1)

# Draw Categorical Plot
def draw_cat_plot():
    # Create DataFrame for cat plot using `pd.melt` using just the values from 'cholesterol', 'gluc', 'smoke', 'alco', 'active', and 'overweight'.
    df_cat = df.melt(df, id_vars=['cardio'], value_vars=['cholesterol', 'gluc', 'smoke', 'alco', 'active', 'overweight'])

    # Group and reformat the data to split it by 'cardio'. Show the counts of each feature. You will have to rename one of the collumns for the catplot to work correctly.

    #group by cardio and count each feature

  #df_cat = 

    # Draw the catplot with 'sns.catplot()'

sns.catplot(data=df_cat, kind='count', x='variable', hue='value', col='cardio')

    # Do not modify the next two lines
    return fig

# Draw Heat Map
def draw_heat_map():
    # Clean the data
    df_heat = None

    # Calculate the correlation matrix
    corr = None

    # Generate a mask for the upper triangle
    mask = None

    # Set up the matplotlib figure
    fig, ax = None

    # Draw the heatmap with 'sns.heatmap()'

    # Do not modify the next two lines
    return fig

Could you link to your code on

Here is my code :slight_smile: and your user name is perfect for me right now, I’m literally losing mine over this haha :’)

Hello there,

Just so you know, I have gone and edited your post to wrap the URL within backticks (`). The reason for this is the links cause annoying formatting on the forum, which prevents Campers from being able to see/click the link.

If I go to the link, it runs for me no problem, so I can’t help you with that.
It throws an error for wrong indentation, so you gotta fix that.

Thank you! I’ve managed to resolve the indent issue, now I just need to work out my 'TypeError: melt() got multiple values for argument ‘id_vars’ error haha
