pandasパッケージを使用してファイルからdataframeデータ構造にデータを読み込み、そのうちの1列が時間です.
その列のタイプはSeriesで、時間のデフォルトは文字列タイプです.
3.コード

import pandas as pd
import datetime

INPUT_PATH = "D:/Code/pythonCode/dataScience/resources/data/xx.csv"


df = pd.read_csv(INPUT_PATH)

print(" type(df['time_block']) = ", type(df['time_block']))
time_block = df['time_block'].head()

print(" type(time_block) = ", type(time_block))
print(time_block)

for time_in in time_block:
    print("type(time_in) = ", type(time_in))
    print(time_in)
    time_date = datetime.datetime.strptime(time_in, "%Y-%m-%d %H:%M:%S")
    print(" type(time_date) ", type(time_date))
    print(time_date)
    print(" type(time_date.date()) = ", type(time_date.date()))
    print(time_date.date())
    print(" type(time_date.time()) = ", type(time_date.time()))
    print(time_date.time())
