You should use 'is' for comparing boolean values ;)

suggestion: handle condition that user call GetTime without StartTimer will be more robust. Reset timer

Narendra Sisodiya (author) 11 years, 7 months ago  # | flag

@Leon -- Actually, StartTimer is needed because user can start timer at any time. So we can have precise starting point in our code. Also, Did you noticed, that if you call StartTimer again, it will behave like a ResetTimer. Let me know, what you think on this, may you write code what changes you want to have ?

Leon means if the user call t.GetTime() without calling t.StartTimer() first, your program will get an error

Can somebody submit code to handle this ?? I am noob to python coding..
