从字符串格式转换后无法打印时间

from datetime import datetime

# 错误的格式
time_str = "2023-10-01 12:34:56"
try:
    time_obj = datetime.strptime(time_str, "%Y-%m-%d %H:%M:%S")
    print(time_obj)
except ValueError as e:
    print(f"Error: {e}")

# 正确的格式
time_obj = datetime.strptime(time_str, "%Y-%m-%d %H:%M:%S")
print(time_obj)

from datetime import datetime
import pytz

time_str = "2023-10-01 12:34:56"
time_zone = pytz.timezone('Asia/Shanghai')

# 解析为本地时间
local_time = datetime.strptime(time_str, "%Y-%m-%d %H:%M:%S")
local_time = local_time.replace(tzinfo=pytz.utc).astimezone(time_zone)
print(local_time)

!pip install python-dateutil

from dateutil import parser

time_str = "2023-10-01 12:34:56"
time_obj = parser.isoparse(time_str)
print(time_obj)
