Mundarija kirish I. Bob pythonning o'ziga xosligi va modullar modullarni skriptlar sifatida bajarish Modul qidirish yoʻli standart modullar 1 II.

Ro’yxatlar bilan ishlash
Ro‟yxatlar bilan ishlash uchun random modulida ikkita funksiya aniqlangan:
shuffle() funksiyasi ro‟yxatni tasodifiy ravishda aralashtiradi; choice() funksiyasi
ro‟yxatdan tasodifiy bitta elementni qaytaradi. ( 2.1.4-rasm)

numbers = [1, 2, 3, 4, 5, 6, 7, 8]

random.shuffle(numbers)

print(numbers) # 1

random_number = random.choice(numbers)

print(random_number)

2.2 math moduli

Ichki math moduli Pythonda matemetik, trigonometrik va logarifimik
amallarni bajaruvchi funksiyalarni o‟zida jamlaydi. Quyida ulardan bir nechtasi
sanab o‟tilgan:

• 
  pow(num, power) – num sonnini power darajaga ko‟taradi;
  
• 
  sqrt(num) – num sonini kvadratik ildizga oladi;
  
• 
  ceil(num) – soni eng yaqin katta butun songacha yaxlitlaydi;
  
• 
  floor(num) – soni eng yaqin kichik butun songacha yaxlitlaydi;
  
• 
  factorial(num) – sonning faktorialini hisoblaydi;
  
• 
  degrees(rad) – radiandan gradusga o‟tkazadi;
  
• 
  radians(grad) – gradusdan radianga o‟tkazadi;
  
• 
  cos(rad) – radianda burchak kosinusini hisoblaydi;
  
• 
  sin(rad) – radianda burchak sinusini hisoblaydi;
  
• 
  tan(rad) – radianda burchak tangensini hisoblaydi;
  
• 
  acos(rad) – radianda burchak arkkosinusini hisoblaydi;
  
• 
  asin(rad) – radianda burchak arksinusini hisoblaydi;
  
• 
  atan(rad) – radianda burchak arktangensini hisoblaydi;
  
• 
  log(n, base) – base asosga ko‟ra n ning logorifimini hisoblaydi;
  
• 
  log10(n) – n sonning o‟nli logorifimini hisoblaydi.
  

Bir qancha funksiyalarni qo‟lash bo‟yicha misol. (2.2.1-rasm)

import math

# 2 ni 3 darajasi

n1 = math.pow(2, 3)

print(n1) # 8

# yuqoridagi amalni quyidagicha bajarsa ham bo’ladi

n2 = 2 ** 3

print(n2)

# kvadrat ildizga olish

print(math.sqrt(9)) # 3

# yaqin katta butun son

print(math.ceil(4.56)) # 5

# yaqin kichik son

print(math.floor(4.56)) # 4

# radiandan gradusga o’tish

print(math.degrees(3.14159)) # 180

# gradusdan radianga o’tish

print(math.radians(180)) # 3.1415.....

# kosinus

print(math.cos(math.radians(60))) # 0.5

# sinus

print(math.sin(math.radians(90))) # 1.0

# tangens

print(math.tan(math.radians(0))) # 0.0

#logorifm

print(math.log(8, 2)) # 3.0

print(math.log10(100)) # 2.0

2.2.1-rasm
math modulida bir qator o‟zgarmas sonlar ham aniqlangan, PI va E. (2.2.2-rasm)

Import math

radius = 30

# 30 radiusli doira yuzasi

area = math.pi * math.pow(radius, 2)

print(area)

# 10 sonnining natural logarifmi

number = math.log(10, math.e)

print(number)
