create a new table that identifies the maximum value and filters against a date in python

To create a new table that identifies the maximum value and filters against a date in Python, we can use the Pandas library to manipulate and analyze data with SQL-like syntax.

First, we need to import the necessary libraries and read in our data:

main.py
import pandas as pd

# Read in data from csv file
df = pd.read_csv('example_data.csv')
87 chars
5 lines

Next, we can use the groupby() function to group our data by date and find the maximum value for each date:

main.py
# Group data by date and find maximum value for each date
max_df = df.groupby('date').max()
92 chars
3 lines

Finally, we can filter the new table to only show values after a certain date:

main.py
# Filter new table to only show values after a certain date
filtered_df = max_df[max_df.index >= '2022-01-01']
111 chars
3 lines

Now, filtered_df contains a new table that identifies the maximum value and filters against a date.
