Python获取当前时间，昨天，明天时间

from datetime import datetime

# 现在
now = datetime.now()
nowDateTime = now.strftime("%Y-%m-%d %H:%M:%S")

# 5分钟后
afterFiveMin = (now + datetime.timedelta(minutes=5)).strftime("%Y-%m-%d %H:%M:%S")

# 1小时前
oneHourAgo = (now - datetime.timedelta(hours=1)).strftime("%Y-%m-%d %H:%M:%S")

# 昨天
yesterday = (now - datetime.timedelta(days=1)).strftime("%Y-%m-%d %H:%M:%S")

# 明天
tomorrow = (now + datetime.timedelta(days=1)).strftime("%Y-%m-%d %H:%M:%S")

# 后天
afterTomorrow = (now + datetime.timedelta(days=2)).strftime("%Y-%m-%d %H:%M:%S")
