csv file comparison using python -


I tried this script to compare two CSV files: 

  import Csv file1 = open ("1.ccv", "r") reader 1 = csv Reader (File 1) Reader 1. Xx () file2 = open ("2.ccv", "r") reader2 = csv Reader (file2) Reader 2.Entax () File3 = open ("file3.txt", "w") file4 = open ("file4.txt", "w") file1.seek (0, 0) file2.seek (0, 0) list1 = file1.readlines () List2 = file2.readlines () for I in list1: j to list2: if i == j: file3.write (i) file3.write (j) else : File4.write (i) file4.write (j) Continue   
 and output that I'm getting with the header and repeating the mismatched files as well. For example, if my  1.csv  contains  
  name pay 20000 b 15000 c 10000   
  2. CSV  in  
  Name 40000D 10000B15000C9000   
 should be output  
  file 3: b 15000 b 15000 file 4: 20000 a 40000 c 10000 c 9000 ------ (1.csv no d) d 10000    
 
 
 Would not it be easier to compare dictionaries with keywords as keywords and values? There may be a way to populate  dict :  
  import csv csv.register_dialect ('spaces', delimiter = '') Pay 1 = {} open ( 'L1. CCV') L1: Reader 1 = CSV. Reader 1.next () # Skip header salary as reader (L1, Dielect = 'blank space') = 1 line {0]: line [1] for print in line [1] Print pay 1

c - Mpirun hangs when mpi send and recieve is put in a loop -

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...
