[Tutor] syntax error

[Nym City]

Hello,
I am also just trying to understand this code and could not understand the print statement.I would have just used:
 print('cost:$',gross_cost)
Do you mind telling little bit about what: 
print('cost: ${:.2f}'.format(gross_cost))
does do and why one would use this over my plain version?


 Thank you.

Also your print line is, I suspect, wrong.
I assume you want to print gross_cost not cost?

You could also use the format method of the string which
tends to be more flexible:

print('cost: ${:.2f}'.format(gross_cost))
