pandas获取当前时间

datetime.now()用于获取当前的日期和时间

print pd.datetime.now()

#encoding:utf8

import pandas as pd
print("(pd.datetime.now()):")
print (pd.datetime.now())
time = pd.Timestamp('2018-11-01')
print("time = pd.Timestamp('2018-11-01')")
print(time)
time = pd.Timestamp(1588686880,unit='s')
print("pd.Timestamp(1588686880,unit='s'):")
print(time)
time = pd.date_range("12:00", "23:59", freq="30min").time
print("pd.date_range('12:00', '23:59', freq='30min').time")
print(time)
time = pd.date_range("12:00", "23:59", freq="H").time
print("freq=;H;")
print(time)
#要转换类似日期的对象(例如字符串，时代或混合)的序列或类似列表的对象，可以使用to_datetime函数。
# 当传递时将返回一个Series(具有相同的索引)，而类似列表被转换为DatetimeIndex
print("================================================================")
time = pd.to_datetime(pd.Series(['Jul 31, 2009','2019-10-10', None]))
print(time)
