Seaborn Barplot 'width' Argument Error: Troubleshooting and Solution

This error arises because the 'width' parameter in the sns.barplot() function is being passed multiple times. This might occur due to redundant 'width' parameters in your function call.

To fix this, you can either remove the duplicate 'width' parameters or utilize the default value. Here's an example demonstrating the removal of the 'width' parameter:

import seaborn as sns
import pandas as pd

# Create sample data
data = {'Customer ID': ['A', 'B', 'C', 'D', 'E'],
        'Repurchase': [1, 0, 1, 1, 0]}
df = pd.DataFrame(data)

# Calculate repurchase rate
repurchase_rate = df.groupby('Repurchase').count() / df.shape[0]
repurchase_rate.rename(columns={'Customer ID': 'rate'}, inplace=True)

# Plot the bar chart
sns.barplot(x=repurchase_rate.index, y=repurchase_rate['rate'])

This solution ensures that the 'width' parameter is not passed redundantly, resolving the error and allowing you to create your bar plot successfully.
