my time.ctime() is not changing when executing my program each 5 second.

How can I fix it?

My program:

import random
import time

n = 1
future = time.time() + 600

for x in range(5): # program execute 5 times
 print(n)
 print time.ctime(future)
 sensor1 = 'ID': 'A', 'float1': ['A' + str(i) for i in range(1, 17)]
 print(sensor1)
 count = 16 # represents 16 float readings
 for i in range(0, count):
 r = random.random() # generates random real number between 0 and 1
 print(r)

 sensor2 = 'ID': 'B', 'float1': ['B' + str(i) for i in range(1, 17)]
 print(sensor2)
 count = 16 # represents 16 float readings
 for i in range(0, count):
 r = random.random() # generates random real number between 0 and 1
 print(r)
 time.sleep(5) # to wait a second
 n = n + 1

Your problem is that you set a fixed value future, and you are using the same fixed value again and again.

You can print the current time using:

print time.ctime()

You can print the current time + 600 using:

print time.ctime(time.time() + 600)

python time manual specify:

time.ctime([secs])

Convert a time expressed in seconds since the epoch to a string
representing local time. If secs is not provided or None, the current
time as returned by time() is used. ctime(secs) is equivalent to
asctime(localtime(secs)). Locale information is not used by ctime().

Example Code (e.g. saved as time_prints.py):

import time

for x in range(5): # program execute 5 times
 print time.ctime()
 time.sleep(5)

Example output:

$ python time_prints.py
