python使用时间间隔的操作及技巧分享

from datetime import timedelta, datetime

# 创建一个时间间隔
delta = timedelta(days=2, hours=6, minutes=30)
print(delta)  # 输出: 2 days, 6:30:00

# 创建一个日期
date = datetime(2024, 6, 4)

# 添加时间间隔
new_date = date + delta
print(new_date)  # 输出: 2024-06-06 06:30:00

# 减去时间间隔
new_date = date - timedelta(days=1)
print(new_date)  # 输出: 2024-06-03 00:00:00

# 创建两个日期
date1 = datetime(2024, 6, 4)
date2 = datetime(2024, 6, 7)

# 计算时间间隔
interval = date2 - date1
print(interval)  # 输出: 3 days, 0:00:00

delta1 = timedelta(days=3)
delta2 = timedelta(days=5)

# 比较时间间隔
if delta1 < delta2:
    print("Delta1 is less than Delta2")

total_seconds = delta.total_seconds()
print(total_seconds)  # 输出: 207600.0

from dateutil.relativedelta import relativedelta

# 创建一个相对时间间隔
delta = relativedelta(years=+1, months=+1, days=+7)

# 应用相对时间间隔
date = datetime(2024, 6, 4)
new_date = date + delta
print(new_date)  # 输出: 2025-07-11 00:00:00

# 格式化时间间隔
formatted_delta = delta.strftime("%d days, %H:%M:%S")
print(formatted_delta)  # 输出: "2 days, 06:30:00"
