Place all your code inside functions please. IIRC, local variable access
is much faster that way, and you do a lot of lookup for the a local
variable in that code.
import time
def main():
a = 1.0
array = range(1000)
for i in array:
for j in array:
a = a + 0.1
tic = time.time()
main()
toc = time.time()
print toc-tic,' has elapsed'
