# You can form an arbitrarily complex expression using operators available
# in Python.  I will try to give you a flavor of them here.  You can find
# other operators and form more complex expressions.

# Note: As you can see, each new example in this tutorial uses the concepts
# that we have already studied.  So, you need to read the tutorial in the
# order it is presented.  For example, the examples below assumes that you
# understand values, types, variables, assignments, etc.

print 22 + 33 - 10


# Create a few variables with a value assigned to each:

hour = 5
minute = 30 

print hour - 2

print hour*60 + minute

print (3+4)*(40/10)+100

this = "Ham"

that = " and cheese"

more = " for breakfast!"

# The '+' operator has different meaning depending on what type of operands
# it deals with.  If it is dealing with numbers, it will just add as usual.
# If the operands are of string type, it will concatenate the operands.

print this+that+more

# '==' is the operator that tests if its two operands are equal or not
# The result will be True or False

issame = this == that


# If you are not sure of operator precedence between two operators, use
# a pair of parentheses to indicate your intention like this.
# 'not' is the negation operator.

isequal = (not (this == that))

print issame

print isequal
