The packet processing time Python datetime and arrow

 

Get points when the shells used the time handler, you want to get time last month, including the year, month, date, etc.

# 方法一:
today = datetime.date.today()  # 1. 获取「今天」
first = today.replace(day=1)   # 2. 获取当前月的第一天
last_month = first - datetime.timedelta(days=1)  # 3. 减一天，得到上个月的最后一天
print(last_month.strftime("%Y%m"))  # 4. 格式化成指定形式

# 方法二:
today = datetime.date.today()  # 1. 获取「今天」
last_month = today.replace(month=today.month - 1)  # 2.获取前一个月
print(last_month.strftime("%Y%m"))  # 3. 格式化成指定形式

# 方法三: arrow包的使用(pip install arrow)
a = arrow.now()  # 当前本地时间
print(a.timestamp)
print(a.year)
print(a.month)
print(a.day)
print(a.date())
print(a.time())
print(a.shift(months=-4).format("YYYYMM"))
print(a.shift(months=1).format("YYYYMM"))
print(a.shift(hours=1))

#  生成arrow对象
print(arrow.get(1535113845))
print(arrow.get(datetime.date(2018, 7, 24)))
print(arrow.get("2018-08-11 12:30:56"))

Results are as follows:

I would like to be compatible by a method n case is extremely difficult, internal implementation will be very complicated, as the user must also use a lot of confusion, we need to select the most suitable package according to their own business scenarios for processing.
