This article mainly explains the "PYTHON time and string conversion", the content of the article is simple and clear, easy to learn and understand, now please follow the editor's ideas slowly in depth, together to study and learn "PYTHON time and string conversion" bar!

1. Convert string to time [in] from datetime import datetime [in] # string [in] time_str = '2019-06-2019: 23 in 57' [in] time_rel = datetime.strptime (time_str,'%Y-%m-%d% Hlav% MHD% S') [in] print (type (time_rel)) [in] print (time_rel) [out] [out] 2019-06-2019: 23:57

Memory method

Strptime: it actually means str parase time. The string is parsed into time.

Note:

The format of the string determines the date format after the strptime.

For example:

[in] time_rel2 = datetime.strptime (time_str,'%Y%m%d%H:%M:%S') [out] ValueError: time data '2019-06-2019: 23 in 57' does not match format'% Y%m%d%H:%M:%S'2, time converted to string # followed by [in] time_str2 = datetime.strftime (time_rel) above '% Y-%m-%d% HGV% MVA% S') [in] print (type (time_str2)) [in] print (time_str2) [out] [out] 2019-06-2019: 23Rd 5 strings but there is no limit to the format of time conversion to strings # obvious Time can be converted into any format of string [in] time_str3 = datetime.strftime (time_rel,'%Y%m%d%H%M%S') [in] print (time_str3) [out] 20190620192357

Memory method

Strftime: it means str from time. The string comes from time. It must be that time is converted into a string.
