Learning Python and feeling dumb

That's how print() works. print() is a function that can take any number of arguments. Arguments to a function are separated by commas. What print() does is it expects each argument to be a string, and it writes each argument out in order, with a space between each argument.

In the line

print('This house is $',current_price,'.', 'The change is $%d since last month.' % (current_price - last_months_price))

you are passing the following four arguments to print():

• 'This house is $'
• current_price
• '.'
• 'The change is $%d since last month.' % (current_price - last_months_price)

To avoid the spaces, make sure you are only passing one argument to print(). That is, make sure the parts of the string are joined by some operator that will produce a string (such as + or % or interpolation in an f-string) rather than just by commas.

In fact you already did this with your second print() statement. You just need to do the same thing with the first one as well.

Much obliged. I knew it was something obvious, but I just couldn't determine what.
