python - Write a very basic copy from one file into another using command line arguments -

-

I am new to Python and am trying to create one file of the original file in another file program. My code now 

  import sys if len (sys.argv)! = 3: Print 'Usage: File Source Source Destination' Otherwise: Try: infile = open (sys.argv [1]) Outfile = open (sys.argv [2], 'w') except for IOError: print 'source File does not exist 'getline (infile, line) infile.close () outfile.close ()

As you can expect that I am trying to output that if the program If the tries to misuse, then why the program will not work.

I have just written a C ++ program, and it worked fine, but now I have to transfer the same logic to a different syntax.

I am trying to write a line of infile in the string line and then output it I write in the file.

Do not try "c ++" to write in Python. For work in hand: 

  import sys if len (sys.argv)! = 3: print ('use: filecopy source destination') else: try: open with (sys.argv [1], 'r') as inf, open (sys.argv [2], 'w') For outf: inf in line: except for outf.write (line) IOError: print ('{} does not exist or not' read.format (sys.argv [1]))

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
