Python's random.seed () usage

Import Random 

# random number is not the same 
random.seed ()
 Print ( ' random number. 1: ' , random.random ()) 
random.seed () 
Print ( ' random number 2: ' , random.random ()) 

# nonce as 
random.seed (. 1 )
 Print ( ' random number. 3: ' , random.random ()) 
random.seed ( . 1 )
 Print ( ' random number. 4: ' , random.random ()) 
random.seed ( 2 )
 Print ( ' random number. 5: ' , random.random ())

As can be seen SEED () without parameters, each generated random number is not the same, and when the SEED () when parameters, each generated random number is the same, different parameters simultaneously selected random number generated not the same
