### 1. Common fucntions
https://docs.python.org/3/library/turtle.html
### 2. for loop , while loop
### 3. Control flow , if / else
### 4. Operatpr
### 5. Function / def , return type

import turtle

### 1. random class

import turtle
import random
colors =['red','purple','blue','green','yellow','orange']
cody = turtle.Turtle()
for x in range(360):
    cody.pencolor(colors[random.randrange(1,6)])
    cody.width(x/100+1)
    cody.forward(x)
    cody.left(59)


### 2. random class

import turtle
import random
cody = turtle.Turtle()
for n in range(60):
    cody.penup()
    cody.goto(random.randint(-400, 400), random.randint(-400, 400))
    cody.pendown()

    red_amount   = random.randint( 0,  30) / 100.0
    blue_amount  = random.randint(50, 100) / 100.0
    green_amount = random.randint( 0,  30) / 100.0
    cody.pencolor((red_amount, green_amount, blue_amount))

    circle_size = random.randint(10, 40)
    cody.pensize(random.randint(1, 5))

    for i in range(6):
        cody.circle(circle_size)
        cody.left(60)


3. Advance use of random class

import random 
  
print("Number guessing game") 
  
# randint function to generate the  
# random number b/w 1 to 9 
number = random.randint(1, 9) 
  
# number of chances to be given  
# to the user to guess the number  
# or it is the inputs given by user 
# into input box here number of   
# chances are 5 
chances = 0
  
print("Guess a number (between 1 and 9):")  
  
# While loop to count the number 
# of chances 
while chances < 5: 
      
    # Enter a number between 1 to 9  
    guess = int(input()) 
      
    # Compare the user entered number   
    # with the number to be guessed  
    if guess == number: 
          
        # if number entered by user   
        # is same as the generated   
        # number by randint function then   
        # break from loop using loop  
        # control statement "break" 
        print("Congratulation YOU WON!!!") 
        break
          
    # Check if the user entered   
    # number is smaller than   
    # the generated number  
    elif guess < number: 
        print("Your guess was too low: Guess a number higher than", guess) 
  
    # The user entered number is   
    # greater than the generated  
    # number              
    else: 
        print("Your guess was too high: Guess a number lower than", guess) 
          
    # Increase the value of chance by 1 
    chances += 1
          
          
# Check whether the user   
# guessed the correct number  
if not chances < 5: 
    print("YOU LOSE!!! The number is", number)

### if and else

answer = input("Is Python an interpreted language? Yes or No >> ")

if answer == "yes" :
    print("You have cleared the test.")
else :
    print("You have failed the test.")

print("Thanks!")

### for loop exercises

1.

for i in range(5):
    print("I will not chew gum in class.")

2.

for i in range(5):
    print("Please,")
print("Can I go to the mall?")

3.

for i in range(5):
    print("Please,")
    print("Can I go to the mall?")

4.

for i in range(10):
    print(i)

5.

# What does this print? Why?
for i in range(3):
    print("a")
for j in range(3):
    print("b")

6.

for i in range(3):
    print("a")
    for j in range(3):
        print("b")
print("Done")

### while loop

quit = "n"
while quit == "n":
    quit = input("Do you want to quit? ")
