python time performance code example
Example 1: python time code
import time
t0 = time.time()
code_block
t1 = time.time()
total = t1-t0
Example 2: time it python
import time
start = time.time()
print("hello")
end = time.time()
print(end - start)
Example 3: how to use timeit in python 3
import timeit
import_module = "import random"
testcode = '''
def test():
return random.randint(10, 100)
'''
print(timeit.repeat(stmt=testcode, setup=import_module))
Example 4: python system performance
import os
import psutil
pid = os.getpid()
py = psutil.Process(pid)
memoryUse = py.memory_info()[0]/2.**30
print('memory use:', memoryUse)
