the goal of program when user clicks start, timer start, printing label, , shown letters randomly chosen (q,w,e,r), must type fast possible. program time them , give them score based on errors @ end, , stop timer.
i wondering if guys find other errors in code causing that, , if how it. realize code bad, i'm starting in tkinter, , i'm not entirely sure how works yet.
any general comments how improve coding appreciated, comments on how write program want, feel current method not practical/functional.
command= expect function name - without () , parameters.
using command=self.usertypetest(0) run self.usertypetest(0)
, result assigned command=.
but self.usertypetest(0) use self.entry wasn't defined yet.
self.entry defined after tkinter.button(...command=self.usertypetest(0)...)
if need assing function parameters use lambda
command=lambda:self.usertypetest(0) and works.
edit:
full working version:
(i changed variable names)
