tkinter - Update label content on click using Python -


I am trying to update the content of a button, in Python, by clicking on a button For each click, a counter will be raised and the value of the label will be updated with the current value of the counter (J). Here is the code: 

  Import time import import import imported from MySQLdb Tkinter import * j = 0 def PrintNumber (): global JJ + = 1 print j returns mgui = Tk ( ) Mgui.geometry ('200x200') mgui.title ('cue system') st = button (mgui, text = "next customer", command = print number) st.pack () f = PrintNumber () label = label ( Mgui, text = f) label. Pack () mgui.mainloop ()   
 Please kindly, I'm new in Python :)   
 
 
 You can use a tincynt instance to keep a value. If you assign the  textvariable  option to the variable  label  widget for the variable class, it will automatically update as the value of the example changes. Here is an example: Setting the Twinter import * root = Tk () var = IntVar () # from IntVar variable class var.set (0) # as the starting value # Button command is a lambda expression set on var Method calls, logic button (root, text = "next customer", command = lambda: var.set (Var.get (+ 1)) with 1 with # var value (var.get). The TextWire label of the Pack () # label is set to the variable class example label (root, text variable = var). Pack () Menloop ()

But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
