Question

hey i need some help. i'm writing a pretty basic program in python that calculates basic arithmatic. it prompts the user for the operator they want to use. but in the event the user inputs an invalid operator i need a way to correct this.

Answer 1

operators = [ '+', '-', '*', '/' ]
operator = ''

while( operator not in operators ):
operator = raw_input( "Enter an operator ( + - * / ): " )
if( operator not in operators ):
print "Try again stupid"


It wasn't a good day.
