如何将Python日期时间对象转换为UTC？

pip install pytz

from datetime import datetime
import pytz

# 创建一个本地日期时间对象
local_dt = datetime.now()

# 设置时区
local_tz = pytz.timezone('Asia/Shanghai')  # 请根据您所在的时区进行设置
utc_tz = pytz.UTC

# 将本地日期时间对象转换为UTC
local_dt = local_tz.localize(local_dt)
utc_dt = local_dt.astimezone(utc_tz)

print("本地日期时间：", local_dt)
print("UTC日期时间：", utc_dt)

pip install python-dateutil

from datetime import datetime
from dateutil import tz

# 创建一个本地日期时间对象
local_dt = datetime.now()

# 设置时区
local_tz = tz.gettz('Asia/Shanghai')  # 请根据您所在的时区进行设置
utc_tz = tz.UTC

# 将本地日期时间对象转换为UTC
local_dt = local_dt.replace(tzinfo=local_tz)
utc_dt = local_dt.astimezone(utc_tz)

print("本地日期时间：", local_dt)
print("UTC日期时间：", utc_dt)
