The most important story in Indian media for the last 3 months was that of the Bengal elections since the Modi govt gave it all they had to win it. Despite their consistent efforts, they failed to even cross a 3 figure mark.

Analysis

We shall analyze the election data. I have downloaded my data from this website.

All Candidates Data

We have downloaded the data, before starting the analysis I will try to understand the data better.

import pyforest
df=pd.read_csv("west_bengal/west_bengal.csv")
df.info()

Most Imp Constituency

constituency = df['constituency'].value_counts().head(10)fig = px.bar(x=constituency.index, y=constituency, height=500, width=700, title='Top 10 Constituency Name')fig.update_traces(marker = dict(
line = dict(color = "rgb(20, 20, 20)", width = 2)))
fig.show()

Criminal Cases

df.groupby('party')['criminal_cases'].sum().reset_index().sort_values(by='criminal_cases', ascending=False).head(15).style.background_gradient(cmap='Blues')
crime = df[df['criminal_cases']!=0]
crime =crime.groupby(['candidate','party'])['criminal_cases'].sum().reset_index().sort_values(by='criminal_cases',ascending=False)
crime.style.background_gradient(cmap='pink_r')

Observation: BJP candidates have the highest number of criminal cases on them. 1 of the BJP candidate have 27 total cases on him and is still fighting in the election.

Education

fig = px.pie(values=df['education'].value_counts(), names=df['education'].value_counts().index, height=500)fig.update_traces(pull=[0.0,0.0,0.2,0.0], hole=.3, hoverinfo="label+percent", marker=dict(colors=line_colors, line=dict(color='black', width=2)))fig['layout'].update(title='Education Distribution', titlefont_size=20)fig.show()
a4_dims = (19, 7.5)
fig, ax = plt.subplots(figsize=a4_dims)
sns.set(style='darkgrid')
sns.countplot(x ='education',
data = df ,
order = df['education'].value_counts().index ,
palette ="prism")
fig.suptitle('Education Distribution using Bar Chart', fontsize=25)
plt.show()

Observation:25% of all candidates are graduates. Only 18 percent are post-graduate.

Total Assets

df.groupby('party')['total_assets'].sum().reset_index().sort_values(by='total_assets',ascending=False)

Observation: AITC owns the highest amount of assets followed by BJP.

Election Winners 2021 Bengal

The data can be collected from the same website again. The earlier analysis for all the candidates that fought elections. We will be discussing the election results and winner candidates.

bengal=pd.read_csv("bengal_votes.csv")
party_winner = bengal['Party'].value_counts()

fig = px.bar(x=party_winner.index, y=party_winner, height=600, width=1100, title='Party Distribution', text=(bengal['Party'].value_counts()/len(bengal['Party'])*100))
fig.update_traces(textposition='outside',texttemplate='%{text:.4s}%',marker = dict(color = "rgba(255, 0, 0, 0.7)",
line = dict(color = "rgb(20, 20, 20)", width = 2)))
fig.show()

Criminal cases

bengal.groupby("Party")["Criminal Case"].sum().reset_index().sort_values(by="Criminal Case", ascending=False).style.background_gradient(cmap='Blues')
crime = bengal[bengal['Criminal Case']!=0]
crime =crime.groupby(['Candidate','Party'])['Criminal Case'].sum().reset_index().sort_values(by='Criminal Case',ascending=False)
crime.style.background_gradient(cmap='pink_r')

Observation: of the winning members AITC has the highest criminal cases which are obvious since they have 202 members who won in the elections. Mukul Roy from BJP has the highest cases individually.

Education

fig = px.pie(values=bengal['Education'].value_counts(), names=bengal['Education'].value_counts().index, height=500)fig.update_traces(pull=[0.0,0.0,0.2,0.0], hole=.3, hoverinfo="label+percent", marker=dict(colors=line_colors, line=dict(color='black', width=2)))fig['layout'].update(title='Education Distribution', titlefont_size=20)fig.show()
a4_dims = (19, 7.5)
fig, ax = plt.subplots(figsize=a4_dims)
sns.set(style='darkgrid')
sns.countplot(x ='Education',
data = bengal ,
order = bengal['Education'].value_counts().index ,
palette ="prism")
fig.suptitle('Education Distribution using Bar Chart', fontsize=25)
plt.show()

Observation: Highest number of winning candidates(24%) are graduates. 21% of the winning candidates are just 12th pass.

Defectors from re-contesting members

For the data, I will use the website. A lot of candidates shifted parties this time and as media told us that a lot of a lot TMC members had joined BJP before elections. So that’s what I wanted to find out

defectors.value_counts("Remarks").reset_index().style.background_gradient(cmap="Pastel2")

Observation: More people from INC have defected than AITC.
