python3對於時間的處理

1、獲取當前時間戳

float_time = time.time()

2、格式化當前時間

#格式化當前時區時間
now_time = time.strftime('%Y-%m-%d %H:%M:%S')
print(now_time)

3、時間戳轉時間

#時間戳轉爲本地時間
local = time.localtime(1505284047.1286137)
#時間戳轉格林尼治時間
local_s =time.gmtime(1505284047.1286137)
pub_st = time.strftime('%Y-%m-%d %H:%M:%S',local_s)
pub_time = time.strftime('%Y-%m-%d %H:%M:%S',local)
print(pub_time,pub_st)

4、字符串轉時間

#字符串轉化爲時間戳
#pub_time爲時間字符串 time_str爲time類型的時間
time_str = time.strptime(pub_time,'%Y-%m-%d %H:%M:%S')
#ss爲時間戳
ss = str(time.mktime(time_str))
#sss爲格式化時間
sss = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(float(ss)))
print(time_str,ss,sss)

5、%b表示英文縮寫月份

hj =  '31 Jul 2008'
time_str = time.strptime(hj,'%d %b %Y')
ss = str(time.mktime(time_str))
sss = time.strftime('%Y-%m-%d',time.localtime(float(ss)))

print(time_str,sss)

6、英文對應月份字典

time_dict = {'January':'01','February':'02','March':'03','April':'04','May':'05',
             'June':'06','July':'07','August':'08','September':'09','October':'10','November':'11','December':'12'}
