python处理大数字的方法
本文实例讲述了python处理大数字的方法。分享给大家供大家参考。具体实现方法如下：
defgetFactorial(n): """returnsthefactorialofn""" ifn==0: return1 else: k=n*getFactorial(n-1) returnk forkinrange(1,70): print"factorialof",k,"=",getFactorial(k)
运行结果如下：
factorialof1=1 factorialof2=2 factorialof3=6 factorialof4=24 factorialof5=120 factorialof6=720 factorialof7=5040 factorialof8=40320 factorialof9=362880 factorialof10=3628800 factorialof11=39916800 factorialof12=479001600 factorialof13=6227020800 factorialof14=87178291200 factorialof15=1307674368000 factorialof16=20922789888000 factorialof17=355687428096000 factorialof18=6402373705728000 factorialof19=121645100408832000 factorialof20=2432902008176640000 factorialof21=51090942171709440000 factorialof22=1124000727777607680000 factorialof23=25852016738884976640000 factorialof24=620448401733239439360000 factorialof25=15511210043330985984000000 factorialof26=403291461126605635584000000 factorialof27=10888869450418352160768000000 factorialof28=304888344611713860501504000000 factorialof29=8841761993739701954543616000000 factorialof30=265252859812191058636308480000000 factorialof31=8222838654177922817725562880000000 factorialof32=263130836933693530167218012160000000 factorialof33=8683317618811886495518194401280000000 factorialof34=295232799039604140847618609643520000000 factorialof35=10333147966386144929666651337523200000000 factorialof36=371993326789901217467999448150835200000000 factorialof37=13763753091226345046315979581580902400000000 factorialof38=523022617466601111760007224100074291200000000 factorialof39=20397882081197443358640281739902897356800000000 factorialof40=815915283247897734345611269596115894272000000000 factorialof41=33452526613163807108170062053440751665152000000000 factorialof42=1405006117752879898543142606244511569936384000000000 factorialof43=60415263063373835637355132068513997507264512000000000 factorialof44=2658271574788448768043625811014615890319638528000000000 factorialof45=119622220865480194561963161495657715064383733760000000000 factorialof46=5502622159812088949850305428800254892961651752960000000000 factorialof47=258623241511168180642964355153611979969197632389120000000000 factorialof48=12413915592536072670862289047373375038521486354677760000000000 factorialof49=608281864034267560872252163321295376887552831379210240000000000 factorialof50=30414093201713378043612608166064768844377641568960512000000000000 factorialof51=1551118753287382280224243016469303211063259720016986112000000000000 factorialof52=80658175170943878571660636856403766975289505440883277824000000000000 factorialof53=4274883284060025564298013753389399649690343788366813724672000000000000 factorialof54=230843697339241380472092742683027581083278564571807941132288000000000000 factorialof55=12696403353658275925965100847566516959580321051449436762275840000000000000 factorialof56=710998587804863451854045647463724949736497978881168458687447040000000000000 factorialof57=40526919504877216755680601905432322134980384796226602145184481280000000000000 factorialof58=2350561331282878571829474910515074683828862318181142924420699914240000000000000 factorialof59=138683118545689835737939019720389406345902876772687432540821294940160000000000000 factorialof60=8320987112741390144276341183223364380754172606361245952449277696409600000000000000 factorialof61=507580213877224798800856812176625227226004528988036003099405939480985600000000000000 factorialof62=31469973260387937525653122354950764088012280797258232192163168247821107200000000000000 factorialof63=1982608315404440064116146708361898137544773690227268628106279599612729753600000000000000 factorialof64=126886932185884164103433389335161480802865516174545192198801894375214704230400000000000000 factorialof65=8247650592082470666723170306785496252186258551345437492922123134388955774976000000000000000 factorialof66=544344939077443064003729240247842752644293064388798874532860126869671081148416000000000000000 factorialof67=36471110918188685288249859096605464427167635314049524593701628500267962436943872000000000000000 factorialof68=2480035542436830599600990418569171581047399201355367672371710738018221445712183296000000000000000 factorialof69=171122452428141311372468338881272839092270544893520369393648040923257279754140647424000000000000000
