Publications - Python Quick-Start Guide: The Simplified Beginner’s Guide To Python

According to vrl websites, Pythn i n f th mt ulr ding lngug f 2015. Alng with bing a high-lvl nd gnrl-ur rgrmming lngug, Pythn is l bjt-rintd nd n ur. At th m time, a gd number f developers r th wrld have been mking u of Python to rt GUI litin, wbit nd mbil apps. Th differentiating factor tht Python bring t th tbl i that it enables programmers to flh ut nt by writing l nd rdbl d. Th dvlr can furthr tk dvntg f vrl Python frmwrk t mitigate the time nd ffrt required for building large nd complex ftwr litin.

The rgrmming language is urrntly bing ud by a numbr f high-trffi websites including Ggl, Yh Groups, Yahoo Maps, Linux Wkly Nw, Shopzilla nd Wb Thry. Likewise, Pythn also find grt u fr rting gaming, finnil, intifi nd educational applications. Hwvr, developers still u different vrin of th rgrmming lngug. Arding t th ug ttiti nd market hr data of Pythn posted on W3th, currently Pythn 2 i bing ud by 99.4% of wbit, whereas Pythn 3 is being used nly by 0.6% of wbit. Tht is why, it bm ntil fr each rgrmmr t undrtnd different versions of Python, nd it vlutin vr many yr.

Hw Pythn H Bn Evlving over th Yr?

Conceived a Hobby Prgrmming Project

Dit being n f th mt ulr ding lngug f 2015, Pythn w riginlly conceived by Guid van Rum as a hbby project in Dmbr 1989. A Vn Rum' office remained ld during Christmas, he w looking for a hbby rjt tht will k him uid during th hlidy. He lnnd t rt an intrrtr fr a new scripting lngug, nd nmd th rjt Python. Thu, Python was riginlly dignd a ur t ABC programming lngug. Aftr writing th interpreter, Vn Rum made th code ubli in Fbrury 1991. Hwvr, t rnt th n source programming lngug is bing mngd by the Pythn Sftwr Foundation.

Vrin 1 f Pythn

Pythn 1.0 was rld in Jnury 1994. Th mjr rl included a numbr of nw ftur nd funtinl programming tools inluding lmbd, filtr, m nd reduce. Th vrin 1.4 was rld with several new ftur like kywrd arguments, built-in urt for mlx numbers, and a basic frm f dt hiding. Th mjr rl w fllwd by tw minor rl, version 1.5 in Dmbr 1997 nd vrin 1.6 in September 2000. Th vrin 1 of Python lkd th ftur ffrd by ulr rgrmming lngug f th time. But the initil versions rtd a lid fundtin fr development f a wrful and futuriti rgrmming language.

Vrin 2 of Pythn

In October 2000, Pythn 2.0 w released with the new lit mrhnin ftur nd a grbg lltin ytm. Th yntx for th list comprehension ftur w inspired by other funtinl rgrmming lngug lik Hkll. But Pythn 2.0, unlik Hkll, gv preference t alphabetic kywrd over punctuation hrtr. Al, th garbage lltin ytm fftutd lltin f reference yl. Th mjr release w fllwd by several minor releases. Th rl added a numbr of funtinlity t th programming lngug like support fr nested scopes, nd unification f Pythn' classes nd ty int a single hirrhy. Th Pythn Sftwr Foundation has already nnund that thr would b n Pythn 2.8. Hwvr, the Foundation will rvid urt t vrin 2.7 of the programming language till 2020.

Vrin 3 f Pythn

Python 3.0 w rld in December 2008. It came with a vrl nw ftur and enhancements, lng with a numbr f deprecated features. Th deprecated features nd bkwrd inmtibility make vrin 3 f Pythn mltly diffrnt from earlier versions. S mny dvlr still u Pythn 2.6 r 2.7 t avail the features drtd from lt mjr rl. Hwvr, th nw ftur of Pythn 3 md it mr mdrn nd ulr. Many developers even withd t vrin 3.0 f the programming lngug t vil th awesome features.

Python 3.0 replaced rint ttmnt with th built-in print() function, whil allowing programmers t u utm rtr between lin. Likewise, it imlifid the rul f rdring mrin. If th rnd r nt organized in a natural and mningful rdr, th rdring mrin operators can now ri a TyErrr xtin. Th version 3 of the rgrmming lngug furthr uses text nd dt intd f Unicode and 8-bit tring. Whil trting ll code Unid by dfult it rrnt binry data as ndd Unid.

As Pythn 3 is backward inmtibl, th rgrmmr nnt ftur like tring xtin, ld-tyl l, nd imliit rltiv imrt. Also, th developers must b fmilir with hng made to syntax and API. Thy n use a tl lld "2t3" t migrt their litin from Pythn 2 t 3 mthly. Th tl highlight inmtibility nd r f nrn thrugh mmnt nd wrning. The mmnt hl rgrmmr t make hng to the code, nd ugrd their xiting litin t th ltt vrin of rgrmming lngug.

Ltt Versions of Pythn

At rnt, programmers n h ithr vrin 3.4.3 or 2.7.10 f Pythn. Pythn 2.7 nbl dvlr t vil imrvd numeric hndling and nhnmnt fr tndrd library. Th vrin further mk it ir for developers t migrt to Pythn 3. On th thr hnd, Pythn 3.4 comes with several nw ftur nd library modules, security imrvmnt and CPythn implementation imrvmnt. However, a numbr of ftur r drtd in both Pythn API and programming lngug. Th dvlr n still u Pythn 3.4 t vil urt in th lngr run.

Version 4 f Pythn

Pythn 4.0 is xtd t b available in 2023 ftr th release f Pythn 3.9. It will come with ftur tht will hl programmers to switch frm vrin 3 to 4 mlly. Also, thy gin xrin, the xrt Pythn developers can tk dvntg of a numbr of bkwrd compatible features t mdrniz thir xiting litin without utting any xtr time nd ffrt. Hwvr, the developers still hv t wit mny years to gt a lr picture f Python 4.0. Hwvr, thy mut mnitr th latest rl t easily migrt t the version 4.0 of th ulr coding language.

The vrin 2 nd vrin 3 of Pythn are mltly diffrnt frm h thr. S h programmer mut undrtnd th features f th ditint vrin, and mr their funtinlity based n ifi nd of th rjt. Also, he nd to check th version f Pythn that each frmwrk supports. Hwvr, each dvlr mut tk dvntg f th ltt vrin f Pythn t vil nw ftur nd long-term urt.

Bfr yu jum in and start lrning a programming language, it will b hlful to yu if yu undrtnd wht i rgrmming nd hw it works, inluding m rgrmming trminlgy.

A mutr on its wn i jut a ul bx. It' nthing but a bunch f diffrnt hardware items mbld int a ingl unit. At thi point, these hrdwr itm ithr tgthr or individually are f no u. Thi is gd a Car tht h bn assembled. Is the car f ny u without fuel? In the same wy, w need to rvid th computer with ful, in thi case its electricity (though thr existed some ty f mhnil mutr, hr we r rfrring to ltril mhin). A computer t thi int i ntilly jut a big bunch f tiny electronic with tht are ithr n r ff. Nw thi is as good a Cr with enough ful nd n b driven, but no drivr t drive.

W nd a drivr, wh n operate th steering whl, gr, brk, t., whih will mk the r move rund. In the m wy by tting diffrnt mbintin f th switches, yu n mk the mutr d something, fr xml, ly a vid n the screen r ly a music vid thrugh th mutr kr or open a file, t. Nw tlling a mutr whn t with n th with and when to with ff them i in other wrd nthing but intruting a mutr what t d. This i wht Programming i in very iml words.

Generally, computer bginnr rn't nrnd in ntrlling th mutr, new mutr ur r commonly nrnd in lrning more but how it all wrk. Nvrthl thy may be surprised t lrn tht computer programing increases mutr knwldg a whl and it n assist to dr th frfuln nd intimidtin associated with uing a nw mutr.

Cmutr rgrming is creating a succession f mmnd tht nbl th mutr t do m actions. The people wh rgrm mutr (called Cmutr Programers) u a rgrming lngug t mmunit with a mutr. Yu might have hrd of m f th lngug in th past uh as Viul Bi, C++, r Frtrn.

Eh of these lngug diffr by th wy they mmunit with a mutr, th mmnd tht thy bid by r vry ifi. Nt a ingl command f n lngug can b exchanged with the mmnd or lngug of nthr. But ll f them can b ud t control a mutr.

Now, w will be intrduing yu t some of programing's mt basic nt - trting with th mmnd. Cmmnd r the instructions tht a computer nfrm to rfrm n tin. T make them work inid of a rgrm, rgrmr ign mmnd t bjt lik buttn fr xml.

Th commands in a rgrm r pretty wrthl unl thy hv some data t uru programers ithr giv th rgrm m infrmtin to wrk with (lit f names or numbr fr example) or they mk the rgrm generate it' wn dt. Oinlly, th dt comes frm an utid ur like th Intrnt r th mutr that th program resides. Th data tht a rgrm receives is called inut and data tht th program gnrt i lld utut.
