Question

I wrote a simple program to calculate tax for some electrical parts, it goes like this:

print "How much does it cost?",    
price = raw_input()    
print "Tax: %s" % (price * 0.25)    
print "Price including tax: %s" % (price * 1.25)    
raw_input ("Press ENTER to exit")

And I keep getting this error:

Traceback (most recent call last):
  File "moms.py", line 3, in <module>
    print "Tax: %s" % (price * 0.25)
TypeError: can't multiply sequence by non-int of type 'float'

Answer 1

You need to convert the string that’s returned by raw_input() to a float first:

price = float(raw_input("How much does it cost?")) # no need for extra print
