时间模块之 格式化时间含中文报错 'locale' codec can't encode character '\u5e74'

import time

print(time.strftime('%Y年%m月%d日 %H时%M分%S秒'))

　　

执行上面代码会报错  UnicodeEncodeError: 'locale' codec can't encode character '\u5e74' in position 2: Illegal byte sequence

 

解决方式：

time.strftime('%Y{y}%m{m}%d{d} %H{h}%M{f}%S{s}').format(y='年',m='月',d='日',h='时',f='分',s='秒')

　　

 

时间格式化

import datetime
# str转时间格式：
dd = '2020-06-20 11:00:00'
dd = datetime.datetime.strptime(dd, "%Y-%m-%d %H:%M:%S")
print(dd,type(dd))

# 时间格式转str:
dc = dd.strftime("%Y-%m-%d %H:%M:%S")
print(dc,type(dc))

　　

# str转时间格式：
dd = '20200620'
dd = datetime.datetime.strptime(dd, "%Y%m%d")
print(dd,type(dd))

# 时间格式转str:
dc = dd.strftime("%Y%m%d")
print(dc,type(dc))


#2020-06-20转化成20200620
startDate="2020-06-20"
startDate=startDate.replace("-","")
print(startDate)
