Python simple method to format time [strftime function]

This article describes a simple method of formatting time in Python and shares it with everyone for reference, as follows:

walker often uses current time and relative time to calculate the efficiency of program execution, simply noting it for easy copying.

>>> import time
>>> startTime = time.time()
>>> '%.2fs' % (time.time() - startTime) # Relative time
'24.51s'
>>> '{:.2f}s'.format(time.time() - startTime) # Relative time
'37.55s'
>>> time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())) # Format the current time
'2016-01-05 10:34:06'

PS: This site also provides a Unix timestamp conversion tool (summary of timestamp operations in various commonly used languages), which is very practical and provides a reference for everyone:
