Storing user input into hash RUBY -

-

im trying store of user's input hash , loop through hash , display results. input: first name, last name, age, city visited(user input multiple cities until input "exit".

here's got far..and looks except being able separate cities multiple values when multiple cities entered. 

result = "" print "enter first name " first = gets.chomp print "enter last name " last = gets.chomp print "enter age " age = gets.chomp  while true print "enter city" city = gets.chomp if city == "exit"   break end result = result + " " + city end  user_data = { first: first, last: last, age: age, city: result}  puts "#{user_data}"

it's better use array purpose, this:

cities = []  loop   print "enter city: "   city = gets.chomp   if city == "done"     break   end   cities << city end  user_data = { first: first, last: last, age: age, city: cities}

and after can make string representation joining elements of array, example 

cities.join(' ')

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i'm getting error seems occur on machines running windows server 2012 . application written .net 4.0 environment. hypothesis in .net 4.5 isn't playing nicely application. have no other ideas. the application designed create pdf files. calling multiple instances of itself. main application call exe file set of parameters indicate pdf files create. in way can call multiple exe files, speeding process. testing purposes, can disable calls outside programs changing setting create pdf files same program, more slowly. the pdf files saved onto local hard drive. user should have access local drives , administrator privileges. there no hidden folders. as main application goes call new instance of itself, crash. see picture below. either can't use exe file, or can't write local drive. i'm not sure which; if need create log will, can determine if application can't call exe file or if application can't write local drive. however, if run same application adm...
