print()

# operator + when given two string operands produces their concatenation;
# i.e., a new string that is formed by running the two operands together

print( '### operator + performs concatenation' )

a = 'fire'
b = 'fighter'
c = a + b     # c = 'firefighter'  no spaces because we didn't put it there

print( 'a =', a )
print( 'b =', b )

print()

print( 'a + b =', c )

print()

# operator * when one of its operands is a string and the other is an integer,
# produces a new string that is a repeated concatenation of string operand
# indicated by the integer

print( '### * operator produces repeated concatenation' )

m  = '\tWahoo-Wah!\n'
# m string here will include a tab in front of 'Wahoo-Wah' and include a new line
n  = 3

# \ is called an escape character. You must use it in '' to indicate a special character immeidiately after
# '\t' = tabs character
# '\n' = newline character
# '\'' = ' after \ is a regular character and not the end of the string
# '\\' = the second \ is a regular character and not a special \
#   print( 'you can print a backslash like this \\' )

# we can use * between a string (m) and a number (n) to get n copies of the same string (m)
# concatenated together
mn = m * n
nm = n * m

print( 'm = ', m, 'read me' )
# m as it currently stands has a tab character in front of Wahoo-Wah and has a newline
# newline starts a new line --> gives you that space between m =... and then n = 3
print( 'n = ', n )

print( 'm * n =', nm )
print( 'n * m =',     nm )
