## Listado de Proyectos
### 1- Mean-Variance-Standard Deviation Calculator

#### 1.3- Código Creado
```py
import numpy as np

### 2- Demographic Data Analyzer
El archivo CSV utilizado llamado **adult.data.csv** NO lo he cargado en mi repositorio por pesar demasiado. Sin embargo, el archivo se encuentra en la siguiente URL: [Link a Archivo](https://github.com/freeCodeCamp/boilerplate-demographic-data-analyzer/blob/main/adult.data.csv)
#### 2.1- Proyecto Aprobado
#### 2.2- Todos los tests superados
#### 2.3- Código Creado
El código que he creado va después de los comentarios. Cada comentario se refiere a lo que se pide realizar.
```py
def calculate_demographic_data(print_data=True):
# Read data from file
df = pd.read_csv("adult.data.csv")
# How many of each race are represented in this dataset? This should be a Pandas series with race names as the index labels.
race_count = df['race'].value_counts()
# What is the average age of men?
average_age_men = round(df[df.sex=='Male'].age.mean(),1)
# What is the percentage of people who have a Bachelor's degree?
percentage_bachelors = round(((df.education[df.education=="Bachelors"].count())/(df.education.count()))*100,1)
# What percentage of people with advanced education (`Bachelors`, `Masters`, or `Doctorate`) make more than 50K?
# What percentage of people without advanced education make more than 50K?
# with and without `Bachelors`, `Masters`, or `Doctorate`
higher_education = df[df.education.isin(['Bachelors', 'Masters', 'Doctorate'])]
lower_education = df[~df.education.isin(['Bachelors', 'Masters', 'Doctorate'])]
# percentage with salary >50K
higher_education_rich = round((higher_education.salary[higher_education.salary=='>50K'].count()/higher_education.salary.count())*100,1)
lower_education_rich = round((lower_education.salary[lower_education.salary=='>50K'].count()/lower_education.salary.count())*100,1)
# What is the minimum number of hours a person works per week (hours-per-week feature)?
min_work_hours = round(df['hours-per-week'].min(),1)
# What percentage of the people who work the minimum number of hours per week have a salary of >50K?
num_min_workers = round((df.loc[df['hours-per-week']==df['hours-per-week'].min(),['salary']].value_counts())['>50K'],1)
rich_percentage = round((df.loc[df['hours-per-week']==df['hours-per-week'].min(),['salary']].value_counts(normalize=True)*100)['>50K'],1)
# What country has the highest percentage of people that earn >50K?
highest_earning_country = df.groupby(['native-country', 'salary']).size().unstack(fill_value=0).apply(lambda x: (x / x.sum()) * 100, axis=1)['>50K'].idxmax()
#otra forma pd.crosstab()
highest_earning_country_percentage =round(df.groupby(['native-country', 'salary']).size().unstack(fill_value=0).apply(lambda x: (x / x.sum()) * 100, axis=1)['>50K'].max(),1)
# Identify the most popular occupation for those who earn >50K in India.
top_IN_occupation = df.loc[(df.salary=='>50K')& (df['native-country']=='India'),['occupation']].mode().iloc[0,0]
# DO NOT MODIFY BELOW THIS LINE
if print_data:
print("Number of each race:\n", race_count)

print(f"Percentage with Bachelors degrees: {percentage_bachelors}%")

### 3- Medical Data Visualizer
El archivo CSV utilizado llamado **medical_examination.csv** NO lo he cargado en mi repositorio por pesar demasiado. Sin embargo, el archivo se encuentra en la siguiente URL: [Link a Archivo](https://github.com/freeCodeCamp/boilerplate-medical-data-visualizer/blob/main/medical_examination.csv)
#### 3.1- Proyecto Aprobado
#### 3.2- Todos los tests superados
#### 3.3- Código Creado
La generación de cortes cambia el tipo de datos a categorico lo que provoca errores en los tests si no se modifica. Para evitar el cambio de tipo de datos he utilizado el método **where**.
```py
# 1
df = pd.read_csv("medical_examination.csv")
# 2
# df['overweight'] = pd.cut(df['weight']/(df['height']/100)**2,bins=[0,25,np.inf],labels=[0,1])
df['overweight']=np.where(df['weight']/(df['height']/100)**2<=25,0,1)
# 3
#df['gluc']=pd.cut(df['gluc'],bins=[0,1,np.inf],labels=[0,1])
#df['cholesterol']=pd.cut(df['cholesterol'],bins=[0,1,np.inf],labels=[0,1])
df['gluc']=np.where(df['gluc'] <= 1, 0, 1)
df['cholesterol']=np.where(df['cholesterol']<=1,0,1)
# 4
def draw_cat_plot():
# 5
variables=['active', 'alco', 'cholesterol', 'gluc', 'overweight', 'smoke']
df_cat = pd.melt(df,id_vars=['cardio'],value_vars=variables)
# 6
df_cat = df_cat.groupby(["cardio", "variable", "value"]).size().reset_index().rename(columns={0:'total'})
# 7
# 8
fig = sns.catplot(data=df_cat, x="variable", y="total", hue="value", col="cardio", kind="bar", height=4, aspect=1.5 ).figure
# 9
fig.savefig('catplot.png')
return fig
# 10
def draw_heat_map():
f1=(df['ap_lo'] <= df['ap_hi'])
f2=(df['height'] >= df['height'].quantile(0.025))
f3=(df['height'] <= df['height'].quantile(0.975))
f4=(df['weight'] >= df['weight'].quantile(0.025))
f5=(df['weight'] <= df['weight'].quantile(0.975))
# 11
df_heat = df[f1 & f2 & f3 & f4 &f5]
# 12
corr = df_heat.corr()
# 13
mask=np.triu(np.ones(corr.shape), 0).astype(bool)
# 14
fig, ax =plt.subplots(figsize=(12, 6))
# 15
sns.heatmap(corr, mask=mask, annot=True, linewidths=0.5, ax=ax,cmap='inferno',fmt=".1f")
# 16
fig.savefig('heatmap.png')
return fig
