O sıcak ve bulanık hissi istiyorsanız, sadece gitmek ile .
Python 3.6 için bu iki programı yeni bir IDLE başlangıcı altında çalıştırdım ve şu çalışma sürelerini verdim:
0.002000093460083008 Test A
0.0020003318786621094 Test B: with guaranteed close
Yani pek bir fark yok.

if __name__ == '__main__':
print("OK, starting program...")
inTextFile = '/Users/Mike/Desktop/garbage.txt'
# # Test: A: no 'with;
c=[]
start_time = time.time()
c = open(inTextFile).read().splitlines()
print("--- %s seconds ---" % (time.time() - start_time))
print("OK, program execution has ended.")
sys.exit() # END MAINLINE
ÇIKTI:
OK, starting program...
--- 0.002000093460083008 seconds ---
OK, program execution has ended.
