I've has decent experiences with Python in Google Code Jam, with two exceptions. (1) Python can't handle large numbers, so the mere existence of huge integer inputs for the large prime number problem blew up my code since Python could not convert numbers that large. (2) Python is fine with math, but at a certain point of data accumulation, performance just plummets, no matter how good your algorithm is. Overall, though, I haven't had the experience the parent comment did. Either Python works beautifully or it literally just doesn't work, rather than take an hour. I treat it as a challenge, though, as it forces me to be smarter about my implementation.

(1) In what sense do you mean "Python can't handle large numbers"? time python -c 'print (5**(5**5))*(3**(3**3))' \ | python -c 'import sys; print hex(int(sys.stdin.read()))' \ | wc -c 1829 real 0m0.091s user 0m0.149s sys 0m0.027s

Python can't handle large numbers Are you sure? Can you post a number of which you think Python can't handle? >>> int("983728338427643876432784367834678326438763278463276543675324675327867498274982787463273647235347652673547623548628347892374982374862384676235478632894790238409382984782768347683274983274964826487264826482264862384628648723643874268426482634826438742648276487264823764873627463252642654") 983728338427643876432784367834678326438763278463276543675324675327867498274982787463273647235347652673547623548628347892374982374862384676235478632894790238409382984782768347683274983274964826487264826482264862384628648723643874268426482634826438742648276487264823764873627463252642654L >>>

What do you mean Python cannot handle large numbers? It has an arbitrary precision integer data type built in: >>> 3**1000 132207081948080663689045525975214436596542203275214816767783138506080619639097776968725823559509545821006189118620803878014774228964841274390400117588618041128947815623617812548034440554705439703889581746536825491613622083028969185564040848989376093732421718463599386955167650189414350385648747165832010614366132173102768902855220001
