python - Does tuple sort itself when looped through -


I have a tube that has many values ​​that I use to search for some files. I found this method as an input method. I try to search for that value (text) in a file and remove the related result. But I have a requirement that if that text is not found, then search for the 'unknown' value in that file and return the corresponding values. To achieve this, I am planning to add Tupal to 'Unknown' so that if it does not get anything, then it will be something like the 'Unknown' Will return But my question is, if I suppress 'unknown' at the end, looping is used in the same sequence while looping through this tube, in which the elements have been added? I tried to open the python and saw that it hides through it in the same order. But I do not want to accidentally search my code for the 'unknown' value before the intended ones. help please.

Looping on Tupless always goes from the first element to the last. 

  & gt; & Gt; & Gt; In x ('asdf', 5, none): ... print x ... asdf 5 none

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. 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...
