pandas use column as index

Comment

import pandas as pd

# Assuming you have a dataframe called "df" with columns: col1, col2, ...

# To set a specific column as the index, you can use the set_index() function:
df = df.set_index('col_name')  # Replace 'col_name' with the actual column name to be set as index

# Alternatively, you can directly specify the index column while reading a CSV file:
df = pd.read_csv('data.csv', index_col='col_name')  # Replace 'col_name' with the actual column name to be set as index
