[Tutor] a code question, but don't know question's name

Dear all- I am writing a function as follows. def getdata(varlist): eventually I have a variable called "data", which have exactly the same number of columns as the name of variables in varlist. Say varlist=['var1','var2','var3']. I want to assign var1=data[:,0], var2=data[:,1], var3=data[

Re: [Tutor] random number generator

I'm tempted to suggest using a hack to avoid floating point errors. Anyway, it isn't choosing a number to ten decimal places. It's actually out to 11 in both examples you gave. And it evaluates to correct because your guesses were to at least 10 places, which is as far as you account for in the

Hi, i'm actually stuck with a stupid syntax problem. here is a a piece of code i can't debug: kx = (neighbor[1]+agent[1])/(dx-(neighbor[1]+agent[1])) in this line, 'neighbor[1]' and 'agent[1]' are both integers and 'dx' is a float so it gives me the following error: 'ZeroDivisionError: float div

Hi Alan, Thanks for the suggestion, but I am not sure it is what I am after. From your dictionary, for example, I wanted to have a list as: "what is your name?" "where do you live?" then the next time I run the program I will get: "who are you? "what is your address? etc... rather then, what
