2.3.Python dasturlash tilida takrorlanuvchi masalalarni yechish.

Misol:

Takrorlanuvchi algoritmning blok sxemasi

S=0

“N ni kiriting”

BOSHLASH









i=2



I<=100

Tamom

S=s+i*(4+math.log(i))

i=i+1

“S=”,S

Ha

Yoq

3.AMALIY QISM

3.1.Masalaning qo’yilishi.

Ushbu kurs ishida O’zgarmas elektr tokning ishi formulasidan foydalandim. O’zgarmas elektr tokning ishi formulasi dasturini tuzdim.

3.2.Dastur uchun nazariy qism.

O'ZGARMAS ELEKTR TOKI ISHI

A=I*U*t

A____Bajarilgan Ish

I_____Tok kuchi

U_____kuchlanish

T_____vaqt

3.3.Kerakli kutubxonalar

Ushbu kurs ishini bajarishda Python dasturlash tilida Tkinter, math kabi kutubhonalardan foydalaniladi.

Tkinter – ushbu kutubxonani o’rnatish uchun win+R ni bosib,cmd buyrug’i yoziladi va OK bosiladi.

7-rasm.Buyruqlar qatorini ochish

Keyin esa hosil bo’lgan oynada pip instal tkinter yoziladi va ENTER bosiladi.

8-rasm.Tkinterni o’rnatish

Tkinter - bu  Python kutubxonasi bo'lib  unda Tk kutubxonasidan foydalaniladi.. Tk kutubxonasida Tcl dasturlash tilida yozilgan grafik foydalanuvchi interfeysi (GUI) komponentlari mavjud.

Grafik interfeys (GUI) - bu dasturni ochishda ekranda ko'riladigan barcha oynalar, tugmachalar, matn maydonlari, skrollerlar, ro'yxatlar, radio tugmalari, tasdiqlash knopkalari va boshqalarni yaratish mumkin . Ular orqali siz dastur bilan o'zaro aloqada bo'lib, uni boshqarasiz. Ushbu barcha interfeys elementlari vidjet deb nomlanadi.

Ko'pgina GUI kutubxonalari mavjud, ulardan Tk eng ommabopi emas , garchi undan foydalanib juda ko'p loyihalar yozilgan. Bu  Python uchun avtomatik ichiga joylashtirilgan kutubxona .

3.4.Dastur kodi

from tkinter import* oyna=Tk() oyna.title("O'zgarmas tokning ishi") oyna.geometry("500x500") ent=Entry(bg="yellow",font=("Impact",11)) ent.place(x=90,y=0,width=120, height=20) lab1=Label(text="I tok kuchi",bg="#199",font=("Impact",11)) lab1.place(x=0,y=0,width=90, height=20) ent1=Entry(bg="yellow",font=("Impact",11)) ent1.place(x=90,y=40,width=120, height=20) lab2=Label(text="U kuchlanish",bg="#199",font=("Impact",11)) lab2.place(x=0,y=40,width=90, height=20) ent2=Entry(bg="yellow",font=("Impact",11)) ent2.place(x=90,y=80,width=120, height=20) lab3=Label(text="t vaqt",bg="#199",font=("Impact",11)) lab3.place(x=0,y=80,width=90, height=20) lab=Label(text="P",bg="#199",font=("Impact",11)) lab.place(x=0,y=120,width=90, height=20) def a(): lab.config(text=(int(ent.get())*float(ent1.get())*int(ent2.get()))) return tugma=Button(text="Hisobla",bg="#199",command=a,font=("Impact",11)) tugma.place(x=90,y=120,width=122,height=22) oyna['bg']='#001' oyna.mainloop()

4.XULOSA

Ushbu kurs ishida O’zgarmas elektr tokning ishi formulasidan fodalanildi. O’zgarmas elektr tokning ishini topish uchun tuzulgan dastur.Ushbu kurs ishida pythonda qanday ishlashni o’rgandim.Python dasturlash tilidan tkinter,math kutibhonalaridan fodalanib tayyorlangan.
