# Doing Ex. 2 
# 2.a and checking my answer
a,b=5,3
print a
print b

# 2.b and checking my answer
c='test'
print a
print b
print c

# 2.c and checking my answer
a=a%b
print a
print b
print c

# 2.d, trying print for more variables at once andcallable() checking my answer
b*=b
print a, b, c
print b
print c

# 2.e and checking my answer
a=c[1]
print a, b, c

# 2.f and checking my answer
c=a=b=True
print a, b, c

# 2.g and checking my answer
c=not(a or b)
print a, b, c

# 2.h and checking my answer
a=b or c
print a, b, c

# 2.i and checking my answer
b=str(a) + "Love"
print a, b, c

#Exercise 3
# creating the 3 variables according to slide
#breakingDistance = (V/10)*(V/10)
#reactionDistance = (V/10)*3
#stoppingDistance = reactionDistance + breakingDistance

# trying to run stoppingDistance like a function as on slide 11
# stoppingDistance(80) Failed
# stoppingDistance(V=80) Failed

# googled making functions: http://docs.python.org/release/1.5.1p1/tut/functions.html & and using exercise3.py 
def car_stopping_dist(v): 
	breakingDistance = (v/10)*(v/10)
	reactionDistance = (v/10)*3
	stoppingDistance = reactionDistance + breakingDistance
	print stoppingDistance

car_stopping_dist(80.0)
#Yay!

car_stopping_dist(50.0)
car_stopping_dist(100.0)

# Exercise 4 using exercise4.py
import math
print math.pi

def cone_volume(r, h):
	SurfaceArea= math.pi * r * h + math.pi * r * r 
	Volume= 1.0/3.0 * math.pi * r * r * h 
	print SurfaceArea
	print Volume

# checking function
cone_volume(2.0,5.0)
cone_volume(2.7,12.5)

# Exercise 5 using exercise5.py

def celsius_to_fahrenheit(C):
	F= C * 1.8 + 32
	print F
	print C

# checking funchtion without input variable
celsius_to_fahrenheit(-10)

# checking function with input variable
input = -10
celsius_to_fahrenheit(input)

# Exercise 6 using exercise6.py

def indian_takeaway(menu_number):
	x=int(menu_number) - 1
	menu = ['Pizza','Sushi','Rice','Stamppot','Shoarma','Chocolate Cake']
	print menu[x]
	
    
# checking function    
indian_takeaway(2)

# Exercise 7

# just running to see what happens
#x = (5==6)
#y = str(x)    
#print y + [1]

# printing in between to check wat really happens    
x = (5==6)
print x  
y = str(x)    
print y   
''' print y + 1 gives an error 
because you can not put an integer and a string together,
print y + [1] gives an error 
because you can not put an list and a string together'''  
print y + 'kaas'
