complete prompt

import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
from sklearn.preprocessing import StandardScaler


def task_func(a, b, columns=['A', 'B']):
    """
    Standardize two lists of numbers using the StandardScaler from sklearn and visualize the standardized values using a bar plot.

    Parameters:
        a (list): A list of numbers.
        b (list): Another list of numbers.
        columns (list, optional): Column names for the resulting DataFrame. Defaults to ['A', 'B'].

    Returns:
        pd.DataFrame: A DataFrame containing the standardized values.
        matplotlib.axes.Axes: Axes object of the displayed bar plot.

    Requirements:
        - numpy
        - pandas
        - sklearn.preprocessing
        - matplotlib.pyplot

    Example:
        >>> df, ax = task_func([1, 2, 3, 4, 5], [2, 4, 6, 8, 10])
        >>> isinstance(df, pd.DataFrame) and isinstance(ax, matplotlib.axes.Axes)
        True
    """

instruct prompt

Standardize two lists of numbers using the StandardScaler from sklearn and visualize the standardized values using a bar plot.
The function should output with:
    pd.DataFrame: A DataFrame containing the standardized values.
    matplotlib.axes.Axes: Axes object of the displayed bar plot.
You should write self-contained code starting with:

Code

import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
from sklearn.preprocessing import StandardScaler
def task_func(a, b, columns=['A', 'B']):
