Python code:

import csv
import pyinputplus as pyip
from pprint import pprint
from random import choices

def main():
    fname = "個股日成交資訊.csv"
    with open(fname, encoding="UTF-8", newline='') as f:
        reader = csv.DictReader(f)
        lst = list(reader)
        print(str.format("{}共有 {} 筆資料", fname.removesuffix(".csv"), len(lst)))
        # Too much data, just show some to demonstration
        n = pyip.inputInt("請輸入要隨機顯示的資料數(1~20): ", min=1, max=20)
        lst_2 = choices(lst, k=n)
        for d in lst_2:
            # Get index of complete data
            idx = lst.index(d)
            print(f"#{idx}")
            pprint(d, indent=2, sort_dicts=False)
