Step five the time of the Python module

The time module, as the name implies, is the module that provides it.

1, time stamp time.time ()

Import time >>> time.time (1522277717.8651874)

The return value is large and the unit is "seconds". The number of seconds between the starting point of January 1, 1970 and the time you use Time.time ().

What is the role of this time stamp? Can be used for timing, such as how much time an operation takes.

2, Sleep Time.sleep ()

Enter both ends of the code together

if a>1:    print(a)    10

After entering print (a) carriage return, the system will print the value of a 10 immediately.

Look at the code again.

if a>1:    time.sleep (5)    print(a)    10

Before print (a), add a line of code Time.sleep (5). This means that the system sleeps for 5 seconds before printing the value of a. Enter the code, we feel the above two pieces of code differences.
