# String Concatenation works with ONLY STRINGS

# operator + when given a string and non-string operands throws up - doesn't work!
#water = 'H' + 2 + 'O' # You can't concatenate a string and a number! You can only concatenate strings!

#print( water )

# built-in function str() returns a text representatiom of its argument
water = 'H' + str( 2 ) + 'O' # This one will work because you're concatenating 3 strings! 'H' + '2' + 'O' -> 'H2O'

print( water )

# To highlight Professor Cohoon's point about printing with + vs. commas
# + - strings
# , - different types

# Code                  # Console
# print('H'+'2'+'O') -> H2O # Concatenated strings
# print('H', 2, 'O') #-> H 2 O # Commas for different types (strings and number) - items are separated by spaces
                              #  when printed
# This is just an example ^
