      Introduction

      compute,rs have, be,come, part and parce,l of e,ve,ryone,’s life,. no matte,r whe,re, you are, in the, world or what life,style, you have,, you inte,ract with at le,ast one, e,ve,ry day. from the, watch you we,ar to the, ble,nde,r in your kitche,n, the,y make, a diffe,re,nce, in how you live,. and with 5g and smart de,vice,s se,t to be,come, mainstre,am in the, ne,ar future,, you must be, te,ch-savvy just to go about your day.

      Simply put, a compute,r is a machine, that has a se,t of instructions — a.k.a. program or software, — to do a spe,cific task(s). without code,s, it is just a pie,ce, of junk hardware,. the, pe,ople, who write, the,m are, calle,d programme,rs, software, de,ve,lope,rs, or code,rs. the, me,dium the,y use, to write, the,se, instructions is known as a programming language,.

      Thanks to rapid te,chnological advance,me,nts, the, compute,r alre,ady give,s a high de,gre,e, of fre,e,dom to programme,rs. you have, storage, de,vice,s in gigabyte,s and e,ve,n te,rabyte,s now inste,ad of just a fe,w kilobyte,s that we,re, mostly available, 30 ye,ars ago. its proce,ssing powe,r has incre,ase,d tre,me,ndously as we,ll. compute,rs are, amazing at re,pe,titive, jobs that pe,ople, cannot do. the,y lack e,motions that te,nd to cause, human e,rror.

      All the,se, things have, le,d to the, inve,ntion of high-le,ve,l programming language,s. the,y have, e,nable,d programme,rs to de,ve,lop comple,x software, solutions that can tackle, virtually any task. this has re,sulte,d in automation be,coming a part of e,ve,ryone,’s pe,rsonal and profe,ssional live,s.

      This book is writte,n for programming e,nthusiasts who want to le,arn how to do it from scratch. e,ve,n though mode,rn programming language,s don’t have, many of the,m, it’s a good ide,a to unde,rstand the, limitations and the, basic conce,pts be,fore, le,arning a spe,cific language,. also, e,ve,ry fie,ld has its own te,rminology. if you don’t familiarize, yourse,lf with it from the, start, you may fe,e,l challe,nge,d whe,n you move, to advance,d conce,pts.

      Mode,rn programming language,s are, ve,ry conde,nse,d. what re,quire,d 100 line,s of code, in an olde,r language,, for instance,, might ne,e,d 5 line,s of code,s only using a mode,rn one,. you’ll notice, late,r that the, code,s he,re, are, as simple, as possible, e,ve,n if it take,s a little, more, line, to achie,ve, the, goal. the,re, are, also programming te,chnique,s available, in e,ve,ry language, for shortcuts and code, optimization.

      Ne,ve,rthe,le,ss, that is not the, main purpose, of this book. the, goal is to impart basic conce,pts of programming and he,lp you le,arn python.

      Why python, you may ask?

      We,ll, for starte,rs, python is as e,ffe,ctive, as a le,arning language, as it is in tackling comple,x tasks. it is one, of the, e,asie,st high-le,ve,l mode,rn programming language,s to le,arn. the, syntax is fairly e,asy to ge,t accustome,d to; it’s powe,rful and inte,grate,s with othe,r programming language,s and syste,ms nice,ly. on top of that, its capabilitie,s are, highly e,xte,ndible,, thanks to doze,ns of librarie,s and e,xte,rnal module,s. afte,r you have, le,arne,d programming and python conce,pts within this book, you don’t ne,e,d to switch to anothe,r language, in the, future, to pursue, furthe,r skills.

      Chapte,r 1: programming basics

      all programming language,s have, the, same, conce,pts at the, core,. ove,r the, ye,ars, though, the,y have, e,volve,d to offe,r more, powe,r and re,lie,ve, code,rs from worrying about minute, de,tails.

      The, first programming language, i le,arne,d was basic in school. the, only thing i got from it was printing my name, te,n time,s on the, scre,e,n, but that software, intrigue,d me, e,nough to pursue, programming as a profe,ssion. the, proble,m was, i made, the, mistake, of le,arning a language, without knowing its unde,rlying conce,pts. it was fine, at first, but as i starte,d to e,xplore, advance,d ide,as, the,y be,came, almost impossible, to unde,rstand.

      To he,lp you avoid the, same, issue,, we, will discuss the, basic conce,pts in this chapte,r.

      Inte,gral programming conce,pts

      It is important to unde,rstand how programming language,s diffe,r. some, of the,m are, suitable, for te,xt proce,ssing, graphics, mathe,matical applications, or ge,ne,ral purpose,s.

      The,re, is no standard classification syste,m for programming language,s. it de,pe,nds on the, crite,ria you use, to classify the,m. he,re, is a simplifie,d ve,rsion of that:

      Low-le,ve,l language,s

      During the, e,arly 20th ce,ntury, compute,rs had limite,d re,source,s. it was the, programme,r’s duty to ke,e,p track of re,source, usage, whe,n writing a program. compute,rs also had limite,d capabilitie,s as the,y only unde,rstood a small se,t of instructions. the,se, are, some, of the, re,asons why low-le,ve,l language,s came, into e,xiste,nce,.

      Machine, language,

      This is the, only language, that compute,rs unde,rstand be,cause, it comprise,s the, binary code,s that compute,r hardware, use,s. during the, machine, language, e,ra, programming was not e,ve,n a distinct fie,ld. the,re, we,re, no standards, and writing programs was a nightmare,. have, you se,e,n margare,t hamilton’s picture, along with the, software, that she, wrote, for the, apollo program that he,lpe,d a man land on the, moon? if not, do it and re,ad he,r story. you’ll unde,rstand what i am trying to say. late,r on, programme,rs we,re, able, to use, he,xade,cimal code,s. still, the, e,ntire, proce,ss was ve,ry complicate,d.

      As a de,monstration of how comple,x and le,ngthy the, coding proce,ss was in machine, language,, he,re,’s the, binary code, conve,rsion of the, two-word phrase, he,llo unive,rse,!

      Asse,mbly language,

      Asse,mbly language,s we,re, the, first one,s to pave, the, way for proble,m solving using compute,rs on a comme,rcial scale,. long binary code,s we,re, re,place,d with short alphanume,ric code,s that we,re, e,asie,r to input and store,. digital input de,vice,s like, ke,yboard be,came, mainstre,am, so punch cards e,nde,d up be,ing obsole,te,.

      High-le,ve,l language,s

      All mode,rn programming language,s are, high-le,ve,l. the,y give, you fre,e,dom from hardware, conside,rations to e,xe,cute, a program. programme,rs focus on achie,ving re,sults while, the, programming platform doe,s the, re,source, manage,me,nt, which is not re,quire,d in most case,s due, to the, advance,d compute,r syste,ms that we, have, nowadays.

      Proble,m-orie,nte,d language,

      Programming language,s like, java, pe,rl, and python are, proble,m-orie,nte,d. the,y e,nable, programme,rs to focus on solving the, task at hand and forge,t about the, hardware, re,source,s. it’s all about the, final product. coding has be,come, e,asie,r and the,re, are, so many re,source,s available, that you don’t ne,e,d to do e,ve,rything from scratch. you can pick re,ady-made, module,s and re,purpose, the,m to fit your re,quire,me,nts.

      Natural programming language,

      We, alre,ady have, de,vice,s that proce,ss human language,s on a limite,d scale, and e,ve,n de,te,ct diffe,re,nt voice,s and acce,nts. furthe,r progre,ss is happe,ning rapidly in the, fie,ld of artificial inte,llige,nce, (ai) with the, obje,ctive, of giving human-le,ve,l inte,lle,ct and fre,e,dom of choice, to compute,rs and e,nabling the,m to make, inde,pe,nde,nt de,cisions. at the, he,art of this are, the, natural programming language,s that’ll allow de,vice,s to se,amle,ssly unde,rstand human language,. have, you se,e,n a scie,nce,-fiction movie, about a human-like, robot who live,s and participate,s in the, socie,ty like, the, re,st of us? this is whe,re, we, are, he,ade,d.

      Inte,rpre,te,rs and compile,rs

      In all high-le,ve,l language,s, the, programs are, e,ithe,r inte,rpre,te,d or compile,d for the, compute,r to unde,rstand what ne,e,ds to be, done,.

      In inte,rpre,te,rs, e,ach line, of code, is translate,d to machine, language, and e,xe,cute,d as soon as it’s e,nte,re,d. inte,rpre,te,r language,s are, use,ful for te,sting and le,arning. an e,xample, of such language, is ruby.

      In compile,rs, the, e,ntire, program is conve,rte,d to machine, language, calle,d obje,ct code, and save,d for future, e,xe,cutions. if the, original program isn’t change,d, compile,r ignore,s the, conve,rsion ste,p and e,xe,cute,s the, obje,ct code,, which make,s the, proce,ss faste,r. this te,chnique, is good for large, software, that strain available, re,source,s. an e,xample, of this language, is c.

      Python is basically an inte,rpre,te,r language, but also offe,rs compile,r option for large, programs. it highlights the, ve,rsatility of the, language, once, again.

      Important de,finitions

      Syntax

      Syntax is the, se,t of rule,s that gove,rns how to write, code, in a programming language,. just like, re,al-life, language,s, it’s e,sse,ntial to follow the, spe,cific syntax to avoid une,xpe,cte,d re,sults.

      Writing algorithms is an age,-old me,thod of solving proble,ms
