The pictures in the blog cannot be displayed, I didn't quite understand how to use inspectors. The blog mentioned that "The Variables window got a new column highlighted in red above", but I do not see this column when I debugging, I click to enlarge the image did not respond.

Is there a problem with my test data？

import fun1
def demo():
    '''
    return None
    '''
    fun1.abc()
    b=1
    c=b
    d=c
    e=d
    matrix = [
        [1, 2, 3],
        [4, 5, 6],
        [7, 8, 9]
    ]

    # 打印整个二维列表
    print(matrix)
    f=e

demo()

Variable inspectors support specific classes. Currently PyScripter ships with just one supporting pandas dataframes. You can write your own for other data types.
