python - How to make 'seat' in user input returned as a float -


so in short python program, wrote:

print "welcome receipt program!" while true:      seat = raw_input('enter value seat: ["q quit"] ')     if seat not seat.isdigit():         print "i'm sorry {} isn't valid. please try again.".format(seat)     if seat == 'q':         break     else:         continue  print "*****" total = seat.count('$') print total

how set so, whenever user enters number (a float specifically) seat (currently not possible in snippet), continues code , adds user inputs? beginner apologies if it's obvious answer.

print "welcome receipt program!" seats = [] while true:      seat = raw_input('enter value seat: ["q quit"] ')     if seat == 'q':         break     try:         seats.append(float(seat))     except valueerror:         print "i'm sorry {} isn't valid. please try again.".format(seat)  print "*****" print '$', sum(seats)

note order in check values of input important (checking 'q' first before trying convert float)

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
