Printing:
print()
write()
str() returns representations of values
repr() generates representations read by the interpreter

s = 'Hello, world.'
str(s)
'Hello, world.'
repr(s)
"'Hello, world.'"

a = 10
b = 20
c = a + b

# Keeping it simple
print("sum of", a , "and" , b , "is" , c) 

#convert variable into str
print("sum of " + str(a) + " and " + str(b) + " is " + str(c)) 

# print in tuple way
print("Sum of %s and %s is %s: " %(a,b,c))  

#New style string formatting
print("sum of {0} and {1} is {2}".format(a,b,c)) 

# use repr()
print("sum of " + repr(a) + " and " + repr(b) + " is " + repr(c))

# Use .format:
print("Total score for {0} is {1}".format(name, score))
Or:
print("Total score for + name + " is " + score)
