Here are the cheat sheet / notes

🏗️ Data Structures

🔠 Variables

Basic method to assign values to a variable 👇🏻

name = 'Rafeh Qazi'
age = 25


>>> print(name)
>>> print(age)

Rafeh Qazi
25

More ways to assign values to variables 👇🏻

width, height = 400, 500

>>> print(width)
>>> print (height)

400
500

📥 Taking Inputs

You have to assign the value of your input directly to a variable.

your_name = input('Please enter your name:')
print('Hi ' + your_name)

>>> Please enter your name:
>>> Rafeh 

Hi Rafeh

🐍 Data Types

🪢 Strings

Strings can be etither words or sentences (and even numbers somtimes)

name = 'Rafeh'
country = 'USA'
city = 'Los Angeles'

💯 Numbers

There are two number data types 👇🏻

🧱 Integers

age = 28
weight = 146

🏖️ Float

temperature = 65.3
longBeachToLAX = 20.7

💡 Booleans

Indicates whether somethin is true or false.

isMyNameQazi = true
doIHaveAPlaystation = false

📝 Lists

Similar to array in JavaScript, but Python uses the word 'Lists'.

fruits = ['🍎', '🍊', '🍌', '🍇', '🍑']

👨🏻‍🔬 Math Operators

Math Operators are used to do mathematical calculations within your application.

➕ Addition

Adding two or more numbers.

print(5 + 5)
>>> 10

num1 = 6
num2 = 7

print(num1 + num2)
>>> 13

➖ Subtraction

Subtracting two or more numbers.

print(6 - 2)
>>> 4

num1 = 8
num2 = 3

print(num1 - num2)
>>> 5

✖️ Multiplication

Multiplying two or more numbers.

print(6 * 2)
>>> 12

num1 = 8
num2 = 3

print(num1 * num2)
>>> 24

➗ Division

Dividing two or more numbers.

print(6 / 2)
>>> 3

num1 = 24
num2 = 6

print(num1 / num2)
>>> 4

🌫 Floor Division

Rounds the result down to the nearest whole number

print(5 // 2)
>>> 3

📈 Exponentiation

Multiplies the first number with an exponent equal to the second number.

print(6 ** 2) 
# similar to 6*6
>>> 36

num1 = 2
num2 = 6

print(num1 ** num2) 
# similar to 2*2*2*2*2*2
>>> 64

🍪 Modulus

Gives the remainder from the division.

print(5/2)
>>> 1

print(14/3)
>>> 2

🤔 Comparison Operators

Comparison Operators are used to compare variables, etc. within your application.

1️⃣ Is Equal to '=='

Compare if two values are equal and return a boolean.

qaziAge = 28
davidAge = 23

print(qaziAge == davidAge)
>>> False

internetSpeedInLA = 100
internetSpeedinDubai = 100

print(internetSpeedInLA == internetSpeedinDubai)
>>> True

2️⃣ Is Less than '<'

qaziAge = 28
davidAge = 23

print(davidAge < qaziAge)
>>> True

longBeachWeather = 66
sanFranciscoWeather = 57

print(longBeachWeather < sanFranciscoWeather)
>>> False

3️⃣ Is Greater than '>'

qaziAge = 28
davidAge = 23

print(davidAge > qaziAge)
>>> False

longBeachWeather = 66
sanFranciscoWeather = 57

print(longBeachWeather > sanFranciscoWeather)
>>> True

4️⃣ Is Less Than or Equal '<='

print(5 <= 5)
>>> True

print(4 <= 5)
>>> True

print(6 <= 5)
>>> False

5️⃣ Is Greather Than or Equal '>='

print(6 >= 6)
>>> True

print(7 >= 6)
>>> True

print(5 >= 6)
>>> False

📚 Dictionaries

def introducer():
  person = {
    'name': 'Qazi', 
    'shirt': 'Black', 
    'laptop': 'Apple',
    'phone_number': '224-123-3456',
    'assets': 100,
    'debt': 50,
    'favoriteFruits': ['🍎', '🍌', '🍊'],
    'netWorth': lambda: person['assets'] - person['debt']
  }
  
  person['shirt'] = 'Orange'
  person['assets'] = 1000
  print(f"👋 Hi my name is {person['name']}, 
  \n👕 I am wearing a {person['shirt']} shirt, \n👨‍💻 and the laptop I use to code is an {person['laptop']}, \n💰and my net worth is ${person['netWorth']()} USD, \n🥝My favorite fruits are {person['favoriteFruits']}")
  
>>> introducer()

`👋 Hi my name is Qazi, 
👕 I am wearing a Orange shirt, 
👨‍💻 and the laptop I use to code is an Apple, 
💰and my net worth is $950 USD, 
🥝My favorite fruits are ['🍎', '🍌', '🍊']`

🤔 Conditionals (if else)

def weather_to_emoji(weather: str) -> None:
  if weather == 'rain':
    print('☔')
  elif weather == 'cloudy':
    print('🌩️')
  elif weather == 'thunderstorm':
    print('⛈️')
  else:
    print('😎')
  
>>> weather_to_emoji('rain')
'☔'

🍬 For Loops

Example #1: Double Numbers in a List

def double(numbers: list) -> list:
  result = []
  for number in numbers:
    result.append(number * 2)
  return result

>>> double([1, 2, 3, 4, 5])
[2, 4, 6, 8, 10]

Example #2: Find the Max in a List

def find_max(numbers):
  current_max = numbers[0]
  for number in numbers:
    if number > current_max:
      current_max = number

  return current_max

>>> find_max([1, 2, 3, 10, 17, 4, 5, 6])
17

Example #3: Find the Frequency of Words in a Phrase

def word_frequency(phrase):
  result = {}
  words = phrase.split()
  for word in words:
    if word not in result:
      result[word] = 1
    else:
      result[word] += 1

  return result

>>> word_frequency('I love Batman because I am Batman')
{'I': 2, 'love': 1, 'Batman': 2, 'because': 1, 'am': 1}

SPECIAL BUILT-IN FUNCTIONS with Python

>>> sum([1, 2, 3])
6
>>> len([1, 2, 3])
3
>>> max([1, 2, 3])
3
>>> max([1, 2, 3, 10, 5, 7])
10
>>> min([1, 50, -7, 337])
-7

🏗️ Functions

1️⃣ Basic Function without any arguement.

def say_my_name():
    print('Rafeh Qazi')
    print('John')
    print('Kara')
    print('Sam')

say_my_name()
>>> Rafeh Qazi
>>> John
>>> Kara
>>> Sam

2️⃣ Function with one arguement.

def say_my_name(name):
    print(name)


say_my_name('Rafeh')
>>> Rafeh

3️⃣ Function with multiple arguements and a default arguement

def greeting(name, greet='aloha'):
  # Function greeting() takes in 2 arguments, 'name' & 'greet' and it greets the user.

>>> greeting('aloha', 'Qazi')
"👋 aloha Qazi!"
    
print(f"👋 {greet} {name}!")

# Positional arguments 👇🏻
# greeting('Qazi', 'hello')

# Named arguments 👇🏻
# greeting(greet='Hi', name='Qazi')
