python 的 time 与datetime 模块对时间的操作。

# coding:utf-8
import pandas as pd 
import datetime
import time
import numpy as np 
start = datetime.datetime.now().strftime('%Y-%m-%d')
end = (datetime.datetime.now()+datetime.timedelta(days=4)).strftime('%Y-%m-%d')
print(start,end)
data = pd.DataFrame(np.random.randint(-10,10,[5,10]),index=pd.date_range(start,end),columns=None)
print(data)
'''
# ******时间撮转时间*********
newDate = time.time()
print(newDate)
time_local = time.localtime(newDate)
print(time_local)
newLocalDate = time.strftime('%Y/%m/%d %H:%M:%S',time_local)
print(newLocalDate)
# *******时间转换时间撮*********
str_df = str(newLocalDate)
print(str_df)
timeArray = time.strptime(str_df,'%Y/%m/%d %H:%M:%S')
print(timeArray)
time_cuo = time.mktime(timeArray)
print(time_cuo)
'''
# datetime库对时间的操作。
date = time.time()
date = datetime.datetime.fromtimestamp(date)
date = date.strftime('%Y-%m-%d %H:%M:%S')
date = datetime.datetime.strptime(date,'%Y-%m-%d %H:%M:%S')
date = date.strftime('%Y/%m/%d')
print(date)
